Albino plants lack chlorophyll, which means that they cannot photosynthesize. These kinds of plant are unique and can offer information as to the molecular mechanism of chlorophyll degradation and photosynthesis in plants. Here, Arisha et al. explored the differences in gene expression patterns of seedling…

In plants with sexual reproduction, the male contribution (two sperm cells) is necessary to fertilize two female cells, the egg cell that gives rise to the embryo and the central cell that gives rise to the endosperm. In contrast, apomictic plants (0.1% of flowering plants spread over 120 genera) don´t…

With the rising climatological extremes, heat stress is a major concern towards sustainable crop yield and productivity as it impairs several physiological and developmental processes. Due to the sessile lifestyle of land plants, they undergo various acclimation responses to cope with fluctuating temperatures.…

Posttranscriptional events such as splicing are part of the gene regulation toolbox. Previous studies have demonstrated a role for U-rich small nuclear ribonucleoproteins (snRNPs) such as U1 in the control of splicing. In a recent paper in The Plant Cell, Chang et al. identified a splicing factor, RNA…

In Arabidopsis, NONEXPRESSOR OF PR GENES 1 (NPR1) plays an important role in the antagonistic crosstalk of salicylic acid (SA) and jasmonic acid (JA) signalling. It activates SA-induced genes that protect against biotrophic pathogens and suppresses JA-induced genes that protect against necrotrophic pathogens.…

TT2 controls rice thermotolerance through SCT1-dependent alteration of wax biosynthesis Global warming severely affects agricultural harvests, risking food security. To deal with heat stress, plants show different strategies. Indeed, heat increases intracellular Ca2+ levels to activate a heat shock…

Feng Zhu and colleagues investigate the time-resolved mGWAS of dark-induced senescence.  https://doi.org/10.1093/plcell/koab251 By Feng Zhu and Alisdair R. Fernie Background: In cellular circumstances under which nutrients are scarce, plants must degrade polymers to recycle carbon (C) and nitrogen…
