By Dolf Weijers In 2022, The Plant Cell will publish a Focus Issue on Plant Cell Biology. This will only be the second Focus Issue (FI) to be published in the journal, after the inaugural FI on the Biology of Plant Genomes, to appear in 2021. (Many years ago, the journal occasionally published Special Issues, […]
Review: Organelles-nucleus-plasmodesmata signaling, and roles in plant physiology, metabolism and stress responses Plasmodesmata (PD) are pores that connect plant cells and allow the flow of small molecules and information but also viruses. This traffic is tightly regulated, in large part by the deposition or removal of callose that impedes movement. Azim and Burch-Smith review a […]

Plantae Presents – Carlos Ballaré and Haim Trebes Recorded Wednesday November 25 10am EST, 4pm CET Carlos Ballaré: Phytochrome, jasmonate, and the balance between growth and defense Prof. Carlos L. Ballaré studies the mechanisms by which plants obtain environmental information. Carlos graduated as Ingeniero Agrónomo and MSc (University of Buenos Aires, 1984, 1989) and PhD […]
In a rosette-forming plant like Arabidopsis, leaf radial angle is optimized to prevent self-shielding. By contrast, in a plant such as sorghum, leaf vertical angle affects self-shading. A “smart canopy” model has been proposed in which upper leaves have a more upright orientation to allow more light to reach the lower leaves. Mantilla-Perez looked at […]
Within the bacterial genus Xanthomonas there are many plant pathogens, some of which colonize living cells within leaves, and others of which are vascular pathogens that colonize and spread through vascular tissues. Gluck-Thaler et al. looked at genomes from sets of closely related bacteria that are either vascular or nonvascular plant pathogens. They identified a […]
During the Triassic and Jurassic periods (approximately 250 – 140 million years ago), Earth was dominated by gymnosperms including conifers. Today, the number of species and individuals is greatly reduced from their heyday, and instead Earth is dominated by angiosperms. Although it is widely stated that angiosperms outcompeted gymnosperms and pushed them to the harsher […]
