Review: Nuclear Ca2+ signaling in endosymbiosis

The Common Symbiosis Signaling Pathway (CSSP) conveys the perception of endosymbionts (rhizobia or mycorrhizal fungi) at the plasma membrane to the nucleus to initiate transcriptional responses. Calcium oscillations are core to the CSSP, whether the endosymbiont is fungal or bacterial. Barker et al. review the molecular players involved in the CSSP, with a focus on […]

Review: Physics of pollinator attraction

Flowers use a variety of strategies to attract pollinators and ensure successful pollination, including color and scent. Moyroud and Glover review some of the less familiar strategies including physical alterations to reflected light. As one example, conical epidermal cells on snapdragon flower petals focus and scatter light, enhancing petal coloration. Other petals appear glossy due […]

A dephytylase involved in chlorophyll turnover

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 activity, Lin et al. have now identified an enzyme, CLD1, that directly […]

Review: The Plant Microbiota: Systems-Level Insights and Perspectives ($)

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 surfaces), etc. Müller et al. review various aspects of plant microbiota research. Phylogenetic […]

Review: Volvox as a developmental model

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 in cell fate. They conclude with a summary of genetic […]

It was a Great, Green Year: Identification of a Chlorophyll Dephytylase That Functions in Chlorophyll Turnover

IN BRIEF by Jennifer Mach jmach@aspb.org 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 chlorophyll degradation, including its regulatory mechanisms. For example, […]

Best of 2016: Top Topics in The Plant Cell journal

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.
