Chlorophyll has an aliphatic phytol side chain that anchors it to light-harvesting complexes. During senescence, chlorophyll is degraded first by the enzymatic removal of Mg to produce pheophytin, which is dephytlated by pheophytinase. Through the identification of a mutant allele with elevated enzymatic…

Terrestrial plants are hosts to diverse types of microbes, predominantly bacteria, that affect plant health and growth in numerous ways. The major types of plant microbiota include plant pathogens, arbuscular mycorrhizal (AM) fungi, endophytes (residing within plant tissues), epiphytes (residing on plant…

Matt and Umen introduce the multicellular green alga Volvox carteri as a model for developmental studies. They provide an overview of embryonic patterning including the role of asymmetric cell divisions, inversion, (a process with some similarities to vertebrate gastrulation), and the role of cell size…

The transition between vegetative and reproductive stages in the plant life cycle implies a change in the developmental program of the shoot apical meristem to stop developing leaves and start developing floral buds. The factors that allow this transition to happen are many and the underlying mechanisms…

IN BRIEF by Jennifer Mach [email protected] Green may have been the Pantone Color of the Year for 2013 (http://www.pantone.com/color-of-the-year-2013), but 2016 was a great year for papers on chlorophyll research, at The Plant Cell and beyond. In this year, we saw a pile of interesting papers examining…

In Plant Physiology Preview you can get a head start on reading the excellent set of articles from a forthcoming special issue on Pollen Biology. Updates and research articles cover all aspects of this crucial part of reproductive biology, from the complex cell biology that underpins polar growth of…

We’ve highlighted some of the Plant Cell papers that were widely shared, liked, blogged, retweeted and otherwise garnered high-levels of attention this year. Perhaps you can use some holiday-season quiet time to catch up on those you missed. Reviews and Perspectives Creating order from chaos: epigenome…

IN BRIEF by Jennifer Lockhart [email protected] Most plants are hermaphrodites, producing perfect flowers with both male and female functions. In roughly 6% of plants, however, male (usually XY) plants produce only male flowers and female (XX) plants produce only female flowers. These dioecious plants…
