APC/CTE Shapes Rice Architecture from Top to Bottom
Research, The Plant Cell, The Plant Cell: In BriefGibberellins (GAs) and abscisic acid (ABA) affect plant development in an opposite manner. GA is generally considered a growth promoting hormone, whereas ABA signaling, triggered in response to stress, counteracts the GA effects and restricts growth under suboptimal conditions (Vanstraelen and Benkova,…

Climate change is expected to make drought far more severe and frequent for plants all over the world (Bartlett et al., 2016). Drought affects yield, growth, and development…
Y keep your X? Insights into the genetic basis of plant sex chromosome evolution
Research, The Plant Cell, The Plant Cell: In BriefContrary to animals, sex chromosomes in flowering plants (angiosperms) have evolved at least hundreds of times independently, providing an opportunity to unravel the mechanisms underlying their repeated evolution.
In the XY system, the Y chromosome dominantly confers male identity: XY individuals…

On the Importance of Variation: A High-Resolution Map of Copy Number Variants in Arabidopsis
Research, The Plant Cell, The Plant Cell: In BriefLinking genotype to phenotype is a major challenge in plant biology. Phenotypic variation observed between individuals of a same plant species is the consequence of a vast array of genetic variation, including Single Nucleotide Polymorphisms (SNPs) and small or large structural variants including Copy…
