Review: An evolutionary history of genes controlling carpel development (COPB)
Plant Science Research WeeklyCarpels, the female reproductive structures in angiosperms, are the most complex organs in plants. Most of the current knowledge about the molecular mechanism underlying carpel development derives from Arabidopsis. In a new review, Becker summarizes recent studies about the reconstruction of ancestral…

Review: Interplay between turgor pressure and plasmodesmata during development (J Exp Bot)
Plant Science Research WeeklyPlasmodesmata, small cytoplasmic channels connecting adjacent cells, allow small molecules to move and redistribute information and resources. Plasmodesmatal aperture is highly regulated, which is crucial to development and defense. Hernández-Hernández et al. review the contribution of turgor pressure…

Review. The development of the periderm: the final frontier between a plant and its environment (COPB)
Plant Science Research WeeklyCampilho 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…

Transcriptional regulatory framework for vascular cambium development in Arabidopsis roots ($) (Nature Plants)
Plant Science Research WeeklyPlant 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…

Fine control of aerenchyma and lateral root development through Aux/IAA- and ARF-dependent auxin signaling ($) (PNAS)
Plant Science Research WeeklyAuxin 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…

Minimal auxin sensing levels in vegetative moss stem cells revealed by a ratiometric reporter ($) (New Phytologist)
Plant Science Research WeeklyAuxin 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…

Coordinated regulation of pre-mRNA splicing by the SFPS-RRC1 complex to promote photomorphogenesis ($) (Plant Cell)
Plant Science Research WeeklyPhytochromes 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…

A phyB-PIF1-SPA1 kinase regulatory complex promotes photomorphogenesis in Arabidopsis (OA) (Nature Communications)
Plant Science Research WeeklyCONSTITUTIVE 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…
