Gibberellins (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,…

Ananya Mukherjee ORCID ID: 0000-0003-1802-1806 amukherjee3@unl.edu University of Nebraska Lincoln Lincoln, NE 68588   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…

Contrary 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…

Liu, Ren et al. discover how a natural allele of tRNA-modifying GTPase gene PDD leads to pleiotropic developmental defects in rice. Plant Cell https://doi.org/10.1105/tpc.19.00660.  By Hui Liu and Pingli Lu Fudan University and Henan University  Background: Transfer RNAs (tRNAs) are components…

Linking 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…
