Tao et al. identify the transporter for beta amino acids that induce priming in plants. https://doi.org/10.1093/plcell/koac271 By Jurriaan Ton & Chia-Nan Tao, University of Sheffield Background: Specific chemicals can induce long-lasting disease resistance in plants. These chemicals act by…

Microalgae are small, photosynthetic algae that have emerged as important contributors to food and nutrient production. This review describes the many ways they can be grown (e.g., autotrophic, with sunlight or artificial light; heterotrophic, with sugar inputs; or mixotrophic, a combination of both)…

Seeds not only carry the embryo that will germinate and give rise to a new individual, but they are also the vector to the next generation for microorganisms from the mother plant and the environment. Consequently, seeds link the microbiome between plant generations. In this thorough review, Abdelfattah…

Chloroplasts divide by binary fission driven by a protein ring, the position of which is regulated by the Min system (derived from the system in bacteria). The inner envelope membrane protein PARC6 (PARALOG OF ARC6) is a key component. Here Sun et al. generated crystal structures showing that PARC6 interacts…

Generally, light inhibits hypocotyl elongation. Like red and blue light, green light was previously reported to inhibit hypocotyl elongation in several plants. Here, Hao et al. discovered that the inhibition of hypocotyl growth by green light is due to wavelength impurities in the green lights used.…

Unanticipated flooding conditions challenge the survival and overall growth and development of a plant, for example stomatal development is suppressed under submerged conditions. Stomata are microscopic pores on the surface of leaves of a plant that play an important role in the exchange of gases between…

The brassinosteroid (BR) signaling pathway is essential for plant growth and development. BRASSINOSTEROID-INSENSITIVE2 (BIN2) is a GSK3-like kinase, serving as a repressor of the BR signaling pathway. In the absence of BR, BIN2 phosphorylates BRASSINAZOLE-RESISTANT1 (BZR1) family transcription factors…

Floral development has been the object of decades of plant research, yet many fundamental questions remain. One of these is the mechanism by which LEAFY (LFY), the master transcription factor of floral development, works with UNUSUAL FLORAL ORGANS (UFO), an F-box protein, to regulate petal and stamen…
