The Way Out: A Transcriptionally Unique Group of Endosperm Cells Implicated in Nutrient Export to the Embryo
Research, The Plant Cell, The Plant Cell: In BriefSuccessful development of the maize (Zea mays) kernel requires proper nutrient transport and signaling among its genetically distinct components: the embryo that gives rise to the next generation, the endosperm that nourishes the embryo, and the maternal tissues that surround the embryo and the endosperm…

The R-loop: An Additional Chromatin Feature for Gene Regulation in Arabidopsis
Research, The Plant Cell, The Plant Cell: In BriefR-loops are three-stranded nucleic acid structures composed of a DNA-RNA hybrid and a displaced single-stranded DNA. R-loops are stable structures as they form an intermediate A/B conformation of the RNA-DNA hybrid that is more stable than the B form of dsDNA or A form of the dsRNA. Recent evidence reveals…

A Closer Look at Acyl-ACPs in Lipid Metabolism
Research, The Plant Cell, The Plant Cell: In BriefAcyl lipids are a wide range of compounds that have diverse functions in membrane synthesis, energy storage, and signal transduction. Fatty acids are key building blocks of acyl lipids that are synthesized by the fatty acid synthase complex via sequential condensation of two-carbon units to reach lengths…
