Life is Sweeter with Trehalose 6-Phosphate
Research, The Plant Cell, The Plant Cell: In BriefBesides making our daily lives sweeter, sugars are the most important energy source in all organisms. Balancing their availability and regulating their partitioning between tissues are major determinants for growth and development. In plants, sucrose is the main product of photosynthesis and is transported…

The Basis of Glyphosate Resistance in Palmer Amaranth
Research, The Plant Cell, The Plant Cell: In a NutshellMolin et al. describe the sequence and gene organization of an extrachromosomal circular DNA element, the eccDNA replicon, that confers resistance to the herbicide glyphosate in amaranths. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00099

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,…
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…
A Chloroplast tRNA-Modifying Enzyme Functions in Plant Development
Research, The Plant Cell, The Plant Cell: In a NutshellLiu, 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.

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…
Seed-Specific Saponin Biosynthesis in Medicago
Research, The Plant Cell, The Plant Cell: In a NutshellRibeiro, Lacchini et al. discover a seed-specific transcription factor that helps determine the composition of the defense compounds saponins in developing Medicago truncatula seeds. Plant Cell https://doi.org/10.1105/tpc.19.00609
