What quantity of photosystem I is optimum for safe photosynthesis? ($) (Plant Physiol)
Plant Science Research WeeklyPhotosynthesis is one of the most vital and complex processes carried out by plants. During photosynthesis, Photosystem I and II (PSI and PSII) undergo photo-excitation. Excessive photo-excitation can damage and deactivate the PSI by generating reactive oxygen species (ROS). This kind of photoinhibition…
Leaf age dictates abiotic versus biotic stress signalling in Arabidopsis (PNAS)
Plant Science Research WeeklyPlants sense and respond to various external stimuli throughout their lifespan. During stress responses brought forth by abiotic or biotic factors, molecular and physiological adjustments mediated by distinct yet interconnected hormone pathways play critical roles in plant survival. Berens et al. investigate…
Rubisco condensate formation by CcmM in β-carboxysome biogenesis (Nature) ($)
Plant Science Research WeeklyCyanobacterial carbon-dioxide concentrating mechanisms elevate intracellular inorganic carbon as bicarbonate, and then concentrate it as carbon-dioxide around the enzyme Rubisco in specialized protein micro-compartments called carboxysomes. The formation of B-carboxysomes involves an aggregation between…
Plant Science Research Weekly: February 8th
WWR Full PostOpinion: To learn inclusion skills, make it personal
This is a great essay by David Asai, Senior Director for science education at the Howard Hughes Medical Institute. David describes his journey from feeling annoyed at having to attend a multicultural forum to embracing their merit. He describes…
How a Cyst Nematode Alters Plant Host Gene Expression
Research, The Plant Cell, The Plant Cell: In a NutshellVijayapalani et al. find a sugar beet cyst nematode protein effector that epigenetically regulates plant rRNA gene dosage, which is a crucial requirement to promote cyst nematode parasitism. Plant Cell https://doi.org/10.1105/tpc.18.00570.
Background: Cyst nematodes are plant-parasitic animals that…

A Receptor-like Pseudokinase in Stomatal Closure
Research, The Plant Cell, The Plant Cell: In a NutshellSierla et al. show that GHR1 is a receptor-like pseudokinase that acts in stomatal closure through its scaffolding functions rather than by directly phosphorylating its target proteins. Plant Cell https://doi.org/10.1105/tpc.18.00441.
