Chinese plant science and Journal of Experimental Botany

Jonathan IngramThis week’s post was written by Jonathan Ingram, Senior Commissioning Editor / Science Writer for the Journal of Experimental Botany. Jonathan moved from lab research into publishing and communications with the launch of Trends in Plant Science in 1995, then going on to New Phytologist and, in the third sector, Age UK and Mind.

 

In this week of the XIXth International Botanical Congress (IBC) in Shenzhen, it seems appropriate to highlight outstanding research from labs in China. More than a third of the current issue of Journal of Experimental Botany is devoted to papers from labs across this powerhouse of early 21st century plant science.

Collaborations are key, and this was a theme that came up time again at the congress. The work by Yongzhe Gu et al. is a fine example, involving scientists at four institutions studying a WRKY gene in wild and cultivated soybean: in Beijing, the State Key Laboratory of Systematic and Evolutionary Botany at the Institute of Botany in the Chinese Academy of Sciences, and the University of the Chinese Academy of Sciences; and in Harbin (Heilongjiang), the Crop Tillage and Cultivation Institute at Heilongjiang Academy of Agricultural Sciences, and the College of Agriculture at Northeast Agricultural University. Interest here centers on the changes which led to the increased seed size in cultivated soybean with possible practical application in cultivation and genetic improvement of such a vital crop.

 

Crops and gardens

Botanic gardens are also part of the picture. In another paper in the same issue, Yang Li et al. from the Key Laboratory of Tropical Plant Resources and Sustainable Use at Xishuangbanna Tropical Botanical Garden in Kunming (Yunnan) and the University of the Chinese Academy of Sciences in Beijing present research on DELLA-interacting proteins in Arabidopsis. Here the authors show that bHLH48 and bHLH60 are transcription factors involved in GA-mediated control of flowering under long-day conditions.

IBC 2017

Naturally, research on rice is important. Wei Jiang et al. from the National Key Laboratory of Crop Genetic Improvement, Huazhong Agricultural University (Wuhan) describe their research on WOX11 and the control of crown root development in the nation’s grain of choice, which will be important for breeders looking to increase crop yields and resilience.

The other work featured is either in Arabidopsis or plants of economic importance: Fangfang Zheng et al. (Qingdao Agricultural University, also with collaborators in Maryland) and Xiuli Han et al. (Beijing); Yun-Song Lai et al. (Beijing/Chengdu – cucumber), Wenkong Yao et al. (Yangling, Shaanxi – Chinese grapevine, Vitis pseudoreticulata), and Xiao-Juan Liu et al. (Tai-an, Shandong – apple).

 

Development of plant science

Shenzehn has grown rapidly and is now highly significant for life science as home to the China National GeneBank (CNGB) project led by BGI Genomics. The vision as set out by Huan-Ming Yang, chairman of BGI-Shenzhen, is profound – from sequencing what’s already here, often in numbers per species, to innovative synthetic biology.

Shenzehn is also home to another significant institution, the beautiful and scientifically important Fairy Lake Botanic Garden. At the IBC, the importance of biodiversity conservation for effective, economically focused plant science, but also for so many other reasons to do with our intimate relationship with plants and continued co-existence on the planet, was a central theme.

The research highlighted in Journal of Experimental Botany is part of the wider, positive growth of plant science (and, indeed, botany) not just in China, but worldwide. The Shenzehn Declaration on Plant Sciences with its seven priorities for strategic action, launched at the congress, will be a guide for the right development in coming years.

A taste of CRISPR

Dr Craig CormickThis week’s blog was written by Dr Craig Cormick, the Creative Director of ThinkOutsideThe. He is one of Australia’s leading science communicators, with over 30 years’ experience working with agencies such as CSIRO, Questacon and Federal Government Departments.

So what do you think CRISPR cabbage might taste like? CRISPR-crispy? Altered in some way?

Participants at the recent Society for Experimental Biology/Global Plant Council New Breeding Technologies workshop in Gothenburg, Sweden, had a chance to find out, because in Sweden CRISPR-produced plants are not captured by the country’s GMO regulations and can be produced.

Professor Stefan Jansson, one of the workshop organizers, has grown the CRISPR cabbage (discussed in his blog for GPC!) and not only had it included on the menu of the workshop dinner, but also had samples for participants to take away. Some delegates were keen to pick up the samples while others were unsure how their own country’s regulatory rules would apply to them.

 

 

Regulatory issues

The uncertainty some delegates felt about the legality of taking a CRISPR cabbage sample home was a good demonstration of the diversity of regulations that apply – or may apply – to new breeding technologies, such as CRISPR and gene editing – and there was considerable discussion at the workshop on how European Union regulations and court rulings may play out, affecting both the development and export/import of plants and foods produced by the new technologies.

A lack of certainty has meant many researchers are unable to determine whether their work will need to be subjected to costly and time-consuming regulations or not.

The need for new breeding technologies was made clear at the workshop, which was attended by 70 people from 17 countries, with presentations on the need to double our current food production to feed the world in 2050 and reduce crop losses caused by problems such as viruses, which deplete crops by 10–15%.

The two-day workshop, held in early July, looked at a breadth of issues, including community attitudes, gene editing success stories, and tools and resources. But discussions kept coming back to regulation.

Outdated regulations

Regulations of gene technologies were largely developed 20 years ago or so, for different technologies than now exist, and as a result are not clear enough for researchers to determine whether different gene editing technologies they are working on may be governed by them or not.

The diversity of regulations is also going to be an issue, for some countries may allow different gene editing technologies, but others may not allow products developed using them to be imported.

That led to the group beginning to develop a statement that captured the feeling of the workshop, which, when complete, it is hoped will be adopted by relevant agencies around the world to develop their own particular positions on gene editing technologies. It would be a huge benefit to have a coherent and common line in an environment of mixed regulations in mixed jurisdictions.

CRISPR cabbage

And as to the initial question of what CRISPR cabbage tastes like – just like any cabbage you might buy at your local supermarket or farmers market, of course – since it is really no different.

The State of the World’s Plants 2017 by Bursary Winner Harison Andriambelo

This week’s post was written by Harison Andriambelo, a PhD student at the University of Antananarivo, Madagascar. Harison was the awardee of the Early Career Researcher travel bursary from the Society for Experimental Biology in association with the Global Plant Council, enabling him to attend the State of the World’s Plants Symposium at the Royal Botanic Gardens, Kew. Here’s how he got on!

Attending the State of the World’s Plants Symposium 2017 at the Royal Botanic Gardens, Kew, was a fantastic opportunity for me to get a detailed insight into many aspects of plant conservation, including the latest emerging research. Scientists from all over the world attended the symposium and shared results from several ecoregions, including tropical, boreal, and temperate biomes. It was also great to visit the Gardens, which were looking amazing in the British summertime.

As a botanist from Madagascar, I found the focus session on conservation in my country particularly useful, and I really enjoyed the talks by Pete Lowry and George Schatz, both from Missouri Botanic Garden.

Other sessions in the conference highlighted important issues including fires and invasive species. We heard that fire is not always bad for plants, especially in savannah systems, where plant diversity is maintained by the fire regime. I believe better scientific communication to the public is urgently needed on this issue.

Another great session concerned invasive species. I have worked across all the biomes in Madagascar, from humid forests to the dry spiny forest, and I have seen first-hand the effects invasive plants can have. A detailed assessment of invasive plant species in wetlands and in the western dry forests of Madagascar made me more aware of the potential impacts of these species. By attending this symposium, I learned about several programs and efforts by the Invasive Species Specialist Group and will spread information about invasive species management to colleagues once I return to Madagascar.

For me, the highlight of the session on medicinal plants was a talk by the President of Mauritius. It was inspirational to see that scientists can even become a head of state. Such leadership offers great promise for addressing environmental issues at national scale. I am certain that having an ecologist as President in Madagascar would allow much greater progress on conservation issues in my home country, which has many highly threatened endemic species. Scientists can bring their understanding and ability to analyze complex systems to bear on policy. Good leaders can take a long-term holistic view and accord the appropriate priority to the environment in national plans for development.

This symposium allowed me to present some results of my research activities in Madagascar and get feedback from an international group of scientists. A deep discussion with people working at RBG Kew about how to scale information on tree dispersal processes from the plot to landscape scales was very valuable. As they know the Madagascan context, they were very interested in my results and a possible collaboration is on its way.

Finally, this trip to London allowed me to spend more time with my colleague Dr Peter Long at the University of Oxford and to make good progress for my scientific research activities. I am very grateful to the Society for Experimental Biology for supporting my travel to the UK to participate in this meeting.
