R.N. Robertson Travelling Fellowship
Xiaoyang Wei, University of Newcastle
After 3 years of my HDR candidature at the University of Newcastle as a China Scholarship Council student, I returned to China in January 2020 for a two-week holiday to visit my parents who live near Wuhan in Hubei Province. As we all know now, I unwittingly flew into the disaster of the Covid-19 pandemic. Due to the initial lockdown in China, and then the border closures and Australian travel restrictions, I have been stuck in China since then, unable to return to Newcastle. Because of the Covid-19 breakout, all the academic institutes and Universities in China applied tight controls to address the challenge from Covid-19. Consequently, I had no access to any laboratory to conduct my PhD research. Luckily, quick and decisive actions were taken by Chinese government, and the pandemic was totally under control in March and life in China, particularly in Wuhan, gradually came back to normal after a two month-long nation-wide lockdown.

In July 2020, university campuses in China gradually reopened, which provided me a chance to work as a visiting scholar in a biological laboratory. Dr Lu Wang at The University of Newcastle introduced me to Dr Yuan Huang from the Huazhong Agricultural University (HZAU) in Wuhan, China. Dr Huang had previously worked as a visiting scholar in Professor Sergey Shabala’s lab at the University of Tasmania for one year (2017-2018) and now is an associate professor at HZAU. A major focus of his lab’s work is on vascular reconnection mechanisms in grafted cucurbit species. With support from the Core Facilities and Service Centre of the College of Horticulture & Forestry Science of HZAU, his lab has access to a full set of facilities for cell biology research, such as a several Leica fluorescence microscopes, vibratome, freezing microtome, ultra-thin semiautomatic microtome, etc. Access to Dr Huang’s lab enabled me to continue my PhD research overseas, and this was possible, to a large degree, because I received an R.N. Robertson Travelling Fellowship from the Australian Society of Plant Scientists (ASPS). This assisted with research costs, and allowed me to continue and then complete my PhD project in Dr Hunag’s laboratory at HZAU in Wuhan. Working at HZAU has given me an opportunity to gain new experiences in using different facilities particularly in handling with fluorescent microscopes and microtomes, which not only enriched my skills but also broadened my insight in plant cell biology research. However, working with Dr Huang’s group at HZAU has also allowed me to transfer many of the skills that I learned while at Newcastle to colleagues in China.
At HZAU, my PhD research mainly involved in investigating the fine-scale spatial relations between the wall ingrowth deposition in phloem parenchyma (PP) transfer cells (TCs) and other types of phloem cells in leaf minor veins in Arabidopsis. Confocal imaging of Vibratome cross sections and orthogonal reconstruction of minor veins was used to survey the leaves of the Col-0 accession, and also in the transgenic lines pAtSWEET11::AtSWEET11-GFP and pAtSUC2::AtSTP9-GFP which mark the PP and companion cells (CC) respectively. This analysis revealed, unexpectedly, that wall ingrowth deposition was more abundant in PP TCs positioned abaxially in the phloem compared to those positioned adaxially, implying differing contributions to phloem loading across minor veins within the leaf. This arrangement would, however, match recent studies in maize which have suggested that phloem loading occurs more from the lower side of the vascular bundle. Wall ingrowths in PP TCs were initiated exclusively at the interface adjacent to sieve elements (SEs), and the deposition of wall ingrowths adjacent to SEs was more abundant than that seen along PP TC/ CC interfaces in mature minor veins. Furthermore, only PP cells that were adjacent to SEs had wall ingrowths. As AtSWEET11-GFP levels were significantly higher in PP TCs with wall ingrowths, compared to PP cells without these structures, this further supports the role of wall ingrowths in facilitating phloem loading. These results constitute a major section of Chapter 3 of my thesis (submitted December 2021) and the work is now being prepared for publication.

I have also conducted bioinformatics analysis using recently published single cell RNA-seq datasets and unpublished RNA-seq datasets from our Newcastle group, and then generated a list of candidate genes that are potentially involved in wall ingrowth deposition. A role for a sub-set of these genes in PP TC development was then assessed using relevant T-DNA insertional mutants. It is worth mentioning that seed lines for all tested T-DNA insertional mutants were obtained from the Arabidopsis stock centre in China called ‘AraShare’, which saved me considerable time in getting access to T-DNA lines, rather than sourcing them from ABRC. Results from this bioinformatics study which I completed while at HZAU has become Chapter 5 of my thesis.
I give my sincere acknowledgements and thanks to the ASPS for funding my project and I am grateful to the legacy of Professor R.N. Robertson for this opportunity. In a large part, this Fellowship allowed me to continue my PhD research while exiled in China. Many thanks to Dr Yuan Huang and all the students in his lab for their help and friendship at HZAU.
Jan Anderson 2021
Kim Johnson, La Trobe University
I almost didn’t apply for the Jan Anderson Award in 2021. Melbourne had experienced 6-months worth of lock-downs in 2020, home schooling had managed to destroy any semblance of work-life balance and I hadn’t had time to reflect on my academic achievements. With encouragement from mentor and collaborator Professor Tony Bacic, I took stock and realised that, by maintaining strong relationships (remotely!) with my research team, national and international collaborators, we had made significant progress in understanding the role of a group of plant cell wall proteins called hydroxyproline-rich glycoproteins, or HRGPs. I have been fascinated with wall (glyco)proteins for most of my career and have sought to understand how they play such important multifunctional roles in cell wall structure, wall integrity sensing and signalling during development and in response to stress. It is a privilege to work with people who share your scientific passion and to have the recognition of ASPS for these achievements was a real honour. I was delighted to be able to accept the award in person in Melbourne and felt the amazing support of the ASPS community linking in. The Jan Anderson award is a positive way for the society to show its commitment to improving equity, diversity and inclusion now and into the future.
Education and Outreach 2021
Kim Johnson and Monika Doblin, La Trobe University
What will you be eating in 2050 when the world’s population reaches 10 billion? Fake meat? Insects? Gene-edited crops?
These were the types of questions we posed to students, teachers and the public during ‘A taste of tomorrow’, a series of education and outreach activities held in August 2020 hosted by La Trobe University for National Science Week. Activities included live online events with audience participation through polls and Q&A, a ‘future food box’, social media videos, and a website providing educational resources (https://www.tastetomorrow.edu.au).
The main aims of the project were to show that sustainable agriculture and nutrition are essential goals of human endeavour and their delivery is complex, that there are multiple stakeholders, no single correct policy and there is a need for compromise. Involvement of researchers from a range of disciplines aimed to show that science is a human endeavour, scientists are approachable and everyday people just like the audience, and learning about plants and animals is fun for its own sake.
To raise awareness of the events, the La Trobe communications team posted fourteen videos, articles and profiles of researchers and students within the areas of biology, ecology, nutrition, physiology and agronomy, that were viewed over 15,000 times. A website was established to provide authenticity and community resources. The website was the point of contact for attendee registrations and supporting information such as future food ‘fact files’, blogs written by La Trobe students that include researcher interviews, recipes, experiments and school activities.

An important part of our events was a free mystery box of ‘future foods’ containing alternative food snacks delivered in advance to registrants. This engaged a wide variety of audiences with 1,000 boxes sent all over Australia. The boxes were particularly popular with teachers who could see the attraction for engaging students and using future food as a talking point for many areas of the curriculum. Three events were held during Science Week (15-23 Aug) and a launch event on the 5 August, attended by approx. 3000 people. Each involved 5-6 panellists from different disciplines (agriculture research, ecology, psychology, nutrition, sports, farming), and an MC who took the audience through a series of hypothetical future scenarios and food tastings. Feedback from the project showed that the events led to changing attitudes about food and sustainability and the importance of research to our future food security.
We sincerely thank ASPS for recognising our efforts to innovatively engage with the next generation of Australian researchers to raise awareness of the necessity to undertake multi-disciplinary research to solve complex societal issues such as meeting the nutritional requirements of the world’s growing population.
Pasture research funding opportunities now on offer
A fresh suite of grants, awards and scholarships are now on offer through the AW Howard Memorial Trust Inc.
The Trust’s various awards encourage and promote research and investigation in the fields of natural science and social science (including economics) which relate to the development, management and use of pastures.
Established in 1964 to commemorate the unique contribution of Amos Howard in the discovery and use of subterranean clover as a pasture plant in Australia, the Trust twice a year seeks grant applications from the research and academic community.
Applications are currently being sought for AW Howard Memorial Trust Early-Career Research Grants, Grants-In-Aid, Honours and Masters Scholarships, Study Awards, and Pastoral Industry Extension Awards:
- Early-Career Research Grants support research activities that improve the development, management and use of pastures. Grants are limited to $15,000 each.
- Grants-In-Aid, limited to $5000 each, are awarded to projects that: commemorate important contributions to pastoral sciences or industry; distribute scientific innovations to develop pasture use within Australia’s regions; invite prominent overseas pasture scientists to Australia to deliver keynote addresses at relevant conferences or visit regional scientists and community groups involved in pastoral industries; or need essential equipment for pastoral scientific research and development.
- Honours and Masters Scholarships are for projects that facilitate pasture research. Each scholarship offers a stipend of $5000 and operating expenses of $3000. Eligible recipients must be intending to commence approved Honours or Masters tertiary studies with any Australian university.
- Study Awards of up to $5000 are awarded to scientists to undertake overseas study tours or participate in national or international conferences. Tours and conferences must be related to pasture research and within the aims of the Trust.
- The Pastoral Industry Extension Study Awards, worth up to $20,000 each, aim to support study tours that examine successful grazing systems and practices and have the potential to benefit Australian pastoral industries and rural communities.
Applications for all the afore mentioned awards close on March 31.
Former Early-Career Research Grant recipient Dr Beth Penrose strongly encourages others to apply for the funding on offer.
“The funds received through the Trust allow recipients to test their research ideas, build grant track records, be the foundation for larger projects, and help farmers at the same time,” said Dr Penrose, who is a Lecturer in Pasture Science at the University of Tasmania.
Dr Penrose used her grant, awarded in 2020, to investigate the effect of soil nutrients on nodulation of white clover and the status of the white clover seed bank of Tasmanian dairy pastures.
The Grant enabled Dr Penrose to engage Honours student Will Coad who worked closely with farmers during the investigation and has since found employment as a pasture agronomist in Tasmania.

Originally from the United Kingdom, Dr Penrose said attracting funding for research without an Australian funding record was difficult, so the support provided through the Howard Trust had been invaluable.
“It allowed me to undertake preliminary research and has been the catalyst for other pasture-related grants.
“It is fantastic that the Howard Trust is focused on pasture-related studies as there aren’t many funding opportunities focused just on pasture.”
The not-for-profit AW Howard Memorial Trust has awarded more than 400 grants of various descriptions since it was established in 1964 by the then Australian Institute of Agricultural Science (now Ag Institute Australia) through donations from benefactors.
The Trust is managed by a committee drawn from Ag Institute Australia, The Australian
Agricultural and Resource Economics Society, the University of Adelaide, the South
Australian Research and Development Institute which is a division of the SA Department of Primary Industries and Regions (PIRSA) and scientists experienced in crops and pastures including tropical pastures.
Application forms are available on the Trust’s website, https://bit.ly/3f3Pxkw. More information is available via the Trust’s executive officer, email firstname.lastname@example.org.
