Campilho et al. have written an interesting review about the molecular basis of periderm development. During secondary growth (increase in girth) of most gymnosperms and dicots, the outer epidermal layer is gradually replaced by the periderm, which facilitates gas exchange and defense. Periderm is composed…

Plant vascular tissues continue to proliferate post-embryogenesis via the cambium, a lateral meristem. Until recently the transcription factors regulating meristem maintenance and promoting differentiation were still unknown. In this paper, Zhang et al. identified multiple transcription factors using…

Auxin plays a major role in plant development and can alter the developmental program following the stress response. In this paper, Yamauchi et al., have identified the auxin signaling cascade involved in the development of aerenchyma and regulators of this auxin signaling might also be involved in lateral…

Auxin plays multiple developmental roles from embryogenesis to seed development. To understand the mechanism of auxin response in plants, researchers utilize the early-diverging land plant models, Physcomitrella patens and Marchantia polymorpha. In this paper, Thelander et al., have identified a…

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…
