ComBio 2015 was well above my expectation. As a plant physiologist interesting in ion transporter research, I had previosuly attended conferences relevant to my area of expertise and found myself comfortable enjoying the science. ComBio is a combined conference covering multiple fields of science and I had some minor trouble submitting my abstract to the relevant plenary that best aligned with my research topic, which did make me wonder about the scope of science that was to follow. But as the conference began, I realized that the 2015 ComBio was going to provide a big and pleasant experience. Professor Martin Caffrey’s lecture discussed new insights into protein structural biology and how it can effect protein function, which was very interesting from a structural biology perspective. I learn’t that there were new ways to crystallise a protein. Given the current difficulties in crystallizing ion transporters, this new method could potentially be used to solve the structure of ion transporters relevant to my research program. I also learn’t a lot from the epigenetics talks, which could pave new ways for crop biofortification and modification. Overall, ComBio2015 truly broadened my view in science, pushing me to think big.

It’s been a busy start to the year in terms of conferences and workshops relevant to plant research. The bi-annual Plant Reproduction meeting was held from the 18^th to 23^rd of March at the University of Arizona in Tucson. The conference brings together experts from diverse fields stretching all the way from meristem development through to sporogenesis, pollen tube attraction, fertilisation, embryogenesis, endosperm development and fruit growth. The ultimate aim of the conference is to describe fundamental research from model species, such as the discovery of genes, mechanisms and biochemical pathways, which might be used to address current and future challenges in crop reproduction and yield. The conference was well attended with approximately 220 attendees, and the quality of data presented was amazing. Australian attendees included researchers from CSIRO Agriculture, The University of Adelaide and the ACPFG. The highlights were talks from Minako Ueda from the University of Nagoya, who showed stunning videos of fluorescently-tagged Arabidopsis egg cells developing into zygotes, Noni Franklin-Tong from the University of Birmingham, who described her work on transferring the self-incompatibility system from poppy into Arabidopsis, and Li Yuan from UC Davis who won an award for his talk on a histidine kinases that controls central cell development in the Arabidopsis female gametophyte. The discovery of genes controlling or inducing apomixis in maize, Taraxacum and Pennisetum was also a major breakthrough. It was clear from the talks that CRISPR/Cas9 and ChipSeq are now standard techniques in the field, while the capacity to isolate, profile and study previously inaccessible cell types through fluorescence assisted cell sorting (FACS) and microdissection is also rapidly progressing. The next plant Reproduction meeting will be held in Japan in 2018, and I would strongly recommend attending what always proves to be a collaborative, interactive and socially enjoyable meeting.

Another excellent CSIRO workshop was recently held from the 19^th-21^st April in Kiama on the NSW south coast. The workshop, also sponsored by the ASPS, brought together Australian and International researchers from the field of Crop Developmental Genetics to discuss old and new strategies for the improvement of crop yield. Cereal crops such as wheat, barley and sorghum were discussed in addition to research on lupins, canola, tomato and legumes. Talks from international speakers including Jorge Dubcovsky from UC Davis, Junko Kyozuka from Tohoku University, Thorsten Schnurrbusch from IPK Gatersleben and Yuval Eshed from the Weizmann Institute were highlights, while students from CSIRO, ANU, the Universities of Adelaide, Queensland and Monash confirmed that the future of plant developmental genetics in Australia is in good hands. The intention was to use this workshop as a springboard for further collaborative research and meetings; plant developmental genetics is a relatively small field that provides so much promise for translating fundamental discoveries directly into breeding outcomes. As part of this I plan to update the ASPS Plant Development page to include information about the field and the research being undertaken in Australia, hopefully this will act as a useful resource for both students and researchers.

A large majority of the human population depends on rice (Oryza sativa) for survival. Rice production needs to increase by 50% to support a higher demand for food forecasted over the next 35 years due to an increasing human population. Traditional breeding can only increase rice yield by 1% per annum. Switching the less efficient C₃ photosynthetic system of rice to use a more efficient C₄ photosynthesis, would theoretically increase productivity by 50%. The aim of the C₄ Rice Consortium is to add features of C₄ photosynthesis to the C₃ plant, rice. Therefore, it is essential to know whether rice can support the expected increase in metabolite flux between the leaf mesophyll (M) and bundle sheath (BS) cells after all the C₄ biochemistry has been installed. The main pathway for metabolite flux is symplastic, i.e. via the plasmodesmata (PD) connecting M and BS cells. Comparison of the symplastic transport mechanisms between the C₃ monocot crop, rice, and the C₄ plant, Setaria viridis was done by looking at the PD density and pit field distribution between the M and BS cells. Electron microscopy and 3D immunolocalisation showed that Setaria (C₄) has higher PD density and higher pit field area coverage on M/BS cell interface than rice (C₃). Establishing the numerical difference in terms of PD connections between C₃ and C₄ plants is not only relevant for the C₄ Rice Project but also in plant transport and modelling studies.

On behalf of Australian Society of Plant Scientists, I joined Science Meets Parliament (SMP) on the 1^st and 2^nd of March, 2016 in Canberra. The SMP aims to provide scientists unique opportunities to build mutual understanding and connections between scientists and parliamentarians and to better understand the policy making process connecting science and innovation that underpins Australia’s economic, social and environmental wellbeing.

Day 1 of the SMP started with an opening address given by Professor Brian Schmidt (AC, Nobel Laureate and Vice Chancellor of ANU) at the Hotel Realm. Prof Schmidt analysed a broad aspects of Australian Science and offered a few ‘tips’ on how to talk to politicians. This was followed by a vivid discussion and debate on ‘How to turn your science into news’, presented by Kylie Walker (Australian Academy of Science), Paul Bongiorno (Network Ten) and Alison Carabine (ABC radio). The meeting continued with an ‘Interactive session’ on rehearsing for parliamentary meetings and concluded with a Gala dinner at the Great Hall in Parliament House where key note speakers, the Hon Christopher Pyne MP, (Minister for Industry, Innovation and Science) and the Hon Bill Shorten MP (Leader of the Opposition) addressed the audience outlining their policies and visions for the future of Australian science.

Day 2 featured face-to-face group meetings in Parliament House with Ministers, Parliamentary Members and Senators. Their were concurrent sessions on Science and Politics delivered by past and present Federal Chief Scientists, Professors Ian Chubb and Alan Finkel, respectively, as well as Aidan Byrne (ARC CEO Professor) and Senator Kim Carr (Shadow Minister for Higher Education, Research, Innovation and Industry).

The two-day event proved to be a very rewarding experience. It helped to better understand and appreciate the process of formulating science-related policies and decisions developed at the government level. It provided a unique opportunity to network with politicians, journalists and fellow scientists while advocating plant science to the broader community. To the latter, I attached here a photo with the Science Minister Chris Pyne at the Gala diner following his keynote speech and our informal discussion.
