The impact of climate change on endangered plants and lichen
Plant Science Research WeeklyAs global CO2 emissions continue to rise, wildlife faces new challenges due to climate change. The biotic and environmental factors impacted by the rising temperature and sea level pose unprecedented threat to the plants and lichens listed on the Endangered Species Act (ESA). In this paper, the tolerance…
Shifting microbial communities can enhance tree tolerance to changing climates
Plant Science Research WeeklyLike all of Earth’s lifeforms, plants are already experiencing hardships due to the changing climate, and these stresses will get more extreme. Much effort has gone into breeding crops for climate resilience, less on trees which are both more diverse and less genetically tractable. Here, Allsup et…
Review: Climate change impacts on plant pathogens, food security, and paths forward
Plant Science Research WeeklyMuch of what is written about the impacts of climate change on food production is focused on the abiotic stresses that plants will experience, but biotic stresses will be equally impactful, as discussed in this fine review by Singh et al. The challenges in predicting climate impacts on plant disease…
Review. Climate change impacts on seed production and quality
Plant Science Research WeeklyAs the effects of climate change become increasingly severe and evident, there is growing concern about the future of food production. However, unlike its impact on crop yields, there is little clarity on the effects of climate change on the foundation of most agricultural systems: seed production and…
One hundred important questions facing plant science: An international perspective
Plant Science Research WeeklyIn 2011, a group of scientists published an article called “One hundred important questions facing plant scientists”. Now, Armstrong et al. have provided an updated version of this, with an additional effort to draw on contributions from the global community, including non-specialists, to identify…
More warm-adapted species in soil seed banks than in herb layers
Plant Science Research WeeklyClimate change profoundly impacts plant communities, for example, by changing the geographic range of some species and locally extinguishing others. Yet these changes take time, maybe a few years, to be observed. This lag between climate and plant communities changes could result from the soil seed bank…
Plant Cell Focus Issue on climate change and plant abiotic stress biology
Plant Science Research WeeklyThe January 2023 issue of The Plant Cell includes a focus issue on “Climate change and plant stress: From genes to ecosystems”. This timely focus issue has in it commentaries, reviews, and research articles on the topic. I particularly enjoyed reading the two reviews that include short perspectives…
Hormone distribution via hydraulic flux determines root branching
Plant Science Research WeeklyClimate change affects rain patterns and hydrological cycles all over the world, exacerbating water scarcity issues. Root branching is altered by local spatial differences in soil moisture. Indeed, when root tips temporarily lose contact with moisture, root branching stops until the appropriate moisture…
Simulated climate warming decreases fruit number but increases seed mass
Plant Science Research WeeklyThere is a growing number of studies showing the effects of rising temperatures on different aspects of plant life cycles and ecological dynamics. However, little is known about how a warmer world would affect plants' reproductive performance; in other words, how many resources they invest in reproduction…
