Guest Editor : Suresh Damodaran I am a postdoctoral research associate in Dr. Lucia Strader’s lab at WUSTL. My primary area of interest is understanding the role of plant hormones in development. I completed my graduate degree in Dr. Sen Subramanian’s lab at SDSTATE.  Twitter: @SureshDamod   Design…

Phytochromes are a family of red/far-red light photoreceptors, which positively regulate photomorphogenesis upon red-light perception. Photomorphogenesis is driven by light-induced global transcriptional reprogramming, of which phytochromes are one of the most important regulators. In addition to transcriptional…

CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) is one of the best characterized E3 ubiquitin ligases with broad roles as a central repressor of light signaling in plants to cancer biology in mammals. In plants, COP1 interacts with SUPPRESSOR OF PHYA-105 1 family members (SPA1-SPA4) and forms a stable COP1/SPA…

Lateral roots are secondary root organs arising through the dedifferentiation of inner cell layers in the primary root. Nodules arise through symbiosis with rhizobia bacteria in a certain clade of land plants and they also arise through dedifferentiation. Both lateral roots and nodules are part of the…

Lignin makes up to 27% of the dry weight of wood and is important structurally as well as serving as an effective carbon sink. Lignin is produced from monolignol precursors that are released into the apoplast and then polymerized. Previous studies have suggested that the monolignols are produced not…

Adventitious roots typically develop from non-root tissue like shoots either naturally in some species or upon induction by stress in most species. The key roles of auxin signaling in lateral root development are well known but the role of these regulators in adventitious roots with their high phenotypic…

Plants constantly grow post embryonically through shoot and root apical meristems. Multiple transcriptional factors and other regulators fine-tune such growth. Leaf growth from the apical meristem is well studied in the model plant Arabidopsis where two main transcription factors, namely HD-ZIP III (Class…

Plant peptide patterning is popping up everywhere! Now Kawamoto et al. show that a pair of peptides, interacting with receptor proteins, coordinates the placement of ovules in Arabidopsis. They started with a natural variation analysis, which highlighted that several varieties with mutations in the ERECTA…
