Willems et al. establish that meristem organization and development rely on Anaphase Promoting Complex/Cyclosome-mediated breakdown of a cyclin.   Plant Cell https://doi.org/10.1105/tpc.20.00208 By Alex Willemsa,b and Lieven De Veyldera,b aDepartment of Plant Biotechnology and Bioinformatics,…

Because plant cells don’t usually move within an organ, it is possible to trace the developmental program cell by cell, through a technique called clonal analysis. If a single cell can be labeled in some heritable way, then all its progeny will also carry this label. Torres-Martínez et al. randomly…

Greer et al. explore the role of SEIPIN in packaging oils into lipid droplets. Plant Cell https://doi.org/10.1105/tpc.19.00771 By Yingqi Cai, Brookhaven National Laboratory, Department of Biology, Upton, NY 11973 Kent D. Chapman, University of North Texas, BioDiscovery Institute, Denton, TX…

Oldenkott et al. use evolution to their advantage by testing whether independently evolved RNA editors can reciprocally correct the errors of organellar transcripts. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00311. By Bastian Oldenkott and Mareike Schallenberg-Rüdinger, IZMB, University…

Vacuolar-type ATPase (V-ATPase) is a highly conserved enzyme but functionally diverse among eukaryotic cells. V-ATPases couple the energy released by ATP hydrolysis to pump protons across membranes of many cell types. In Arabidopsis, the V-ATPases containing different isoforms of V-ATPase catalytic…

The cambium is a layer of actively dividing cells between xylem and phloem tissues that is responsible for the thickening of primary or lateral roots and stems. Root crops are tightly associated with the cambium regulatory mechanism which is less characterized in root as compared to shoot development.…

Gonzalez Solis et al. describe the metabolic, cellular, and physiological consequences of the complete loss of regulation of sphingolipid biosynthesis. Plant Cell https://doi.org/10.1105/tpc.20.00015  By Ariadna Gonzalez Solis and Edgar B. Cahoon  Background: Glycosphingolipids are molecules…

Classical evolutionary theory states that the probability of a mutation occurring is independent of fitness consequences. However, reassessment of traditional assumptions is warranted with recent discoveries showing that cytogenetic (DNA sequences and epigenetic) features can affect local mutation probabilities.…
