CPK32 regulates cellulose biosynthesis through post-translational modification of cellulose synthase
Plant Science Research WeeklyCellulose in one of the most abundant polymers on the planet and is synthesized by plasma membrane-bound cellulose synthases (CESAs). Phosphorylation plays a role in CESA regulation, however the kinases which catalyse the phosphorylation are not well described. Here Xin et al. identified calcium-dependent…
Gravity sensing involves LZY translocation from statoliths to the plasma membrane
Plant Science Research WeeklyIn plants, gravity sensing is orchestrated by specialized cells called statocytes that contain starch-filled plastids (amyloplasts) called statoliths, whose positions are influenced by the direction of gravity. However, the molecular mechanisms of gravity sensing and signaling are poorly understood.…
Membrane lipid phosphoinositides signature the final step of plant cytokinesis
Plant Science Research WeeklyPhosphoinositides (membrane lipids with cytosolic inositol headgroups carrying phosphate residues at various positions) serve as road markings for membrane and membrane/cytoskeleton dynamics. Here, Lebeco et al. add further detail to the map. Previously the authors showed that the plant-specific enzyme…
Jurassic ZAR; Insights from an atypically conserved immune receptor
Plant Science Research WeeklyIt’s a well-established fact that some proteins are highly variable across species, and others such as histones hardly vary at all. Highly conserved proteins such as histones have very little wiggle room in their structure; small changes can lead to a loss of function. However, for some other proteins…
Adaptive evolution of the enigmatic Takakia moss now facing climate change in Tibet
Plant Science Research WeeklyIn this fantastic, engaging paper, Hu et al. carries the reader from the origins of life on land through the dramatic uplift of the Tibetan plateau and into the modern age of climate change, all through the lens of the “enigmatic” Takakia moss. It’s enigmatic because it has features that are more…
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…
Insights from a survey of mentorship experiences
Plant Science Research WeeklyWhat do mentees want and need from their mentors, and are they getting it? How do factors such as gender identity and internationalism affect the quality of mentor/mentee interactions? Results from a survey of more than 2000 mentees (mostly postdocs and graduate students) are reported, along with a thorough…
Additional time demands on non-native English speakers
Plant Science Research WeeklyAs a monolinguist, I’m in awe of people who can write papers and speak at conferences in a language other than their first, but I never thought to quantify the additional burden that’s place on non-native English speakers. Fortunately, Amano and colleagues decided to ask this question, and the results…

WWR Full PostReview: Strigolactones integrate metabolic and nutritional signals
Strigolactones are a class of hormones first identified in the 1960s as components of root exudates that promote germination of parasitic Striga seeds, and later as a promoter of associations with arbuscular mycorrhizal fungi. Strigolactones…
