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…
Best of 2016: Top Topics in The Plant Cell journal
Blog, Research, Research Blog, The Plant CellWe’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.

The Power of Plasticity in Polyploid Persimmon
Research, The Plant Cell, The Plant Cell: In BriefIN 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…

Evolutionary origins of stomata ($)
Plant Science Research Weekly, ResearchQuestions remain about the evolutionary origins and functions of stomata. They are absent from liverworts, present to a limited extent in mosses, and are found on 410 million year-old fossils of Cooksonia, a leafless plant. Chater et al. show that orthologs of two key transcription factors that control…
Review: Evolutionary perspective on auxin’s role in shoot branching
Plant Science Research Weekly, ResearchShoot branching increases the photosynthetic surface area and the points at which reproductive structures can form. In angiosperms, auxin (specifically, auxin depletion) has been shown to be involved in the initiation and outgrowth of shoot branches. For example, in apical dominance the primary shoot…
Review: Endosperm and Imprinting
Plant Science Research Weekly, Research"The endosperm is often viewed as a complicated and rather strange tissue" begins this review by Gehring and Satyaki. They go on to describe that the endosperm is the site of expression of imprinted genes, which are genes that are expressed soley when inherited from the mother or father. The authors…
Review: Plasmodesmata, pores between cells ($)
Plant Science Research Weekly, ResearchThe cytosol of most plant cells are connected by plasmodesmata, tiny channels that form bridges between adjoining cells (guard cells notably lack plasmodesmatal connections). Water, ions, small molecules, proteins and viruses can move through plasmodesmata. Upon wounding or infection, plasmodesmatal…
Molecular basis for plant growth responses in shade and under competition for light ($)
Plant Science Research Weekly, Research
The wavelenghts of light perceived by a plant are information-rich, and plants integrate information from photoreceptors tuned to different wavelenghts to optimize their growth and development. Because plants absorb red light but not far-red light, a low ratio of red to far-red light indicates vegetative…
