Recognizing featured Plant Cell first authors, December 2016

Recently, we’ve been profiling first authors of Plant Cell papers that are selected for In Brief summaries. Here are the first-author profiles from the December issue of The Plant Cell. Yao-Pin Lin, featured author of Identification of Chlorophyll Dephytylase Involved in Chlorophyll Turnover in Arabidopsis Current Position: Postdoctoral fellow in Agricultural Biotechnology Research Center, Academia […]

Review: Nitrogen sensing in legumes ($)

As a consequence of their ability to fix nitrogen in symbiosis with bacteria, legumes make key contributions to ecosystems and provide protein-rich foods for humans and other animals. Recent years have uncovered the nature of the signals involved in the cross-kingdom dialogues that occur between plant and bacteria and the systemic signals that optimize nodule […]

Domestication impacts on plant–herbivore interactions: a meta-analysis

It is widely stated that domestication has contributed to a decrease in plant resistance to herbivory, but to what extent is this true? In a contribution to a special issue on “Human influences on evolution”, Whitehead et al. describe results of their meta-analysis. Although their data show a consistent reduction in herbivore resistance associated with […]

Epigenetic regulation of sex determination in polyploid persimmon

Although most flowering plants produce flowers with male and female parts, there are exceptions which are broadly classified as dioecious (two houses; each individual is male or female, usually associated with the presence of a sex chromosome) and monoecious (one house, separate male and female flowers in a single individual). Diploid persimmon plants are dioecious; […]

A PNAS trio: DNA methylation and small RNAs in plant reproduction

Three PNAS papers explore DNA methylation and/or small RNAs in plant reproductive development. In angiosperms, sexual reproduction is accompanied by DNA demethylation in certain tissues, particularly those that have a nutritive or supporting role.  Park et al. (10.1073/pnas.1619047114) show that in the endosperm this demethylation occurs on the chromosomes inherited from the central cell and […]

Plant-permeable trehalose 6-phosphate analogues increase yield and resilience ($)

Trehalose-6-phosphate (T6P) is a sugar signaling molecule that regulates how plants allocate and use sucrose, which in turn affects stress resilience and yields. Griffiths et al. designed a plant-permeable, photo-activated T6P analogue that is converted to T6P in planta. Spraying this compound onto plants (Arabidopsis and wheat) increases stress resilience and yields. These results suggest […]

Opinion Paper: Bandwagons I, too, have known (reflections of a plant breeder) ($)

In this entertaining Opinion article written for the 150th anniversary of Mendel’s seminal work, Bernardo reviews “bandwagons” that have come and gone in plant breeding. Early bandwagons such as induced polyploidy are discussed, as well as more recent trends such as trangenics, molecular markers and QTL mapping, association mapping, and genomewide selection. He also summarizes […]
