Special issue: Human-machine collaboration in plant biology
Plant Science Research WeeklyThis is an excellent article to wrap up this year and lead us into the future. Introducing a special issue of Plant Cell Physiology, Nakajima et al. summarize an exciting collection of papers that look at diverse ways that plant biology can be enhanced through “human-machine collaborations”. Some…
A novel way to conduct genome wide association studies for secondary metabolites
Plant Science Research WeeklyPlants produce many specialized metabolites that are often associated with increased plant fitness. Metabolic genome wide association studies (mGWAS) identify enzymes involved in specialized metabolite biosynthesis. However, this relies on identifying metabolites from mass spectrometry data which is…
Breakthrough in the identification of photosynthesis genes in green algae
Plant Science Research WeeklyImagine the everyday delights of foods like bread, ramen, or sushi. Central to these culinary staples is starch, a product of the photosynthesis process in plants. Despite its critical role, people still do not fully understand the regulation and biogenesis of the photosynthesis machinery. In this study,…
Guanylate cyclase activity of TIR1/AFB auxin receptors in rapid auxin responses
Plant Science Research WeeklyAuxin is a pleiotropic plant hormone with diverse functions, many of which are mediated through transcriptional reprograming. However, some auxin responses occur extremely rapidly, ruling out changes in transcription as a mechanism. In 2022, one of the components of an auxin receptor, F-box protein TIR1/AFB,…
Tree or bush? It’s all in the hormones
Plant Science Research WeeklyMuch of our understanding of the molecular underpinning that control shoot architecture comes from studies of annual plants such as Arabidopsis, pea, and rice. This new work by Su et al. investigates shoot branching in a long-lived tree, silver birch (Betula pendula). They started with a naturally occurring…
Diurnal switches in diazotrophic lifestyle increase nitrogen contribution to cereals
Plant Science Research WeeklyUnlike legumes, which form symbiotic associations with nitrogen-fixing bacteria (diazotrophs), high-yielding cereal crops are usually supplemented with inorganic fertilizers that are both energetically and environmentally problematic. Some non-legumes can obtain nitrogen from associations with free-living…
Engineering wheat to reduce the immunoreactivity of gluten
Plant Science Research WeeklySome people cannot eat wheat because they are sensitive to gluten, which is a proteinaceous network of glutenins and gliadins. Gliadins are divided into four classes, ω, γ, α, and β, with ω- and γ-gliadins being the most toxic to gluten sensitive individuals. Hence, there is interest in reducing…
Volatile methyl jasmonate from roots triggers host-beneficial soil microbiome biofilms
Plant Science Research WeeklyVolatile molecules released from plant roots (root VOCs, rVOCs) can diffuse over long distances, thereby increasing the sphere of plant influence. However, their influence on complex soil microbial communities (or microbiomes) and ecological implications are poorly understood, mainly due to technical…
Old reserves and ancient buds fuel regrowth of coast redwood after catastrophic fire
Plant Science Research WeeklyIn recent years we have witnessed catastrophic fires throughout the world, including the redwood forests of California. Although these huge ancient trees are fire resistant, many have died due to the extreme heat generated by these recent fires. Here, Peltier et al. examined patterns of regrowth from…
