Over‐accumulation of abscisic acid in transgenic tomato plants increases the risk of hydraulic failure (Plant Cell Environ.)
Plant Science Research WeeklyABA enhances stomatal closure and so decreases transpiration. Several studies have shown that increasing ABA levels can increase water-use efficiency, so this strategy has been investigated with the goal of obtaining “more crop per drop”. Lamarque et al. investigated physiological and hydraulic effects…
Subdivision of light signaling networks contributes to partitioning of C4 photosynthesis (Plant Physiol)
Plant Science Research WeeklySome plants such as Zea mays partition different components of the photosynthetic pathway in mesophyll cells (MC) and bundle sheath cells (BSC) in a process known as two-cell C4 photosynthesis. For example, light-harvesting reactions carried out by photosystem I and II (PSI and PSII) occur only in the…

Blog, WWR Full PostReview: The nanoscale organization of the plasma membrane and its importance in signaling – a proteolipid perspective
Ample evidence shows that rather than being homogenous, plasma membrane lipids and proteins form distinct nanodomains. Jallais and Ott review plant plasma membrane nanodomains, and…
