Mystery of adventitious root formation in grapevine (Plant Physiol)

Grapevines (Vitis vinifera L.) are clonally propagated by stem cuttings, which depends on the formation of adventitious (stem-borne) roots. In this paper Chen at al., showed the function of microRNA encoded peptides (miPEPs) in adventitious root formation of cultured grape plantlets. MicroRNA biogenesis involves the transcription of microRNA genes (MIR) by RNA pol II to […]

Self-activation loop of STM maintains the meristematic activity of cells at leaf axil (Curr. Biol.)

Plasticity in plant development comes from the meristematic cells that are maintained throughout plant growth and among other things produce lateral organs such as shoot branches.  In this paper, Cao et al. show that the self-activation loop of SHOOT MERISTEMLESS (STM), a meristem marker gene that encodes a homeodomain transcription factor, is important for the […]

Versatile auto-luminescent luciferase-based reporters for spatiotemporal gene expression studies (eLIFE)

Firefly luciferase constructs are extensively used for gene expression studies but require a reaction with an exogenous substrate, so expression to some extent reflects tissue penetrance. Khakhar et al. designed customizable auto-luminescence constructs based on a fungal bioluminescence pathway (FBP) in which caffeic acid, an intermediate of lignin biosynthesis, is converted into luciferin by the […]

Deubiquitinating enzymes UBP12, 13 are antagonistic to E3 ligases BIG BROTHER and DA2 (eLIFE)

Post-translation modifications like ubiquitination and deubiquitination are important to maintain protein homeostasis and in turn plant growth. DA1, and DA1-RELATED PROTEIN 1, 2 (DAR1, DAR2) are latent peptidases activated upon ubiquitination by E3 ligases BIG BROTHER (BB) and DA2. In this paper, Vanhaeren et al. identified UBIQUITIN BINDING PROTEIN 12, 13 (UBP12, 13) as the […]

Integration of light signaling with endogenous developmental pathway to regulate flowering (Mol. Plant)

Response to changing environmental conditions is key for plant reproductive success. Previous studies have implicated FAR-RED ELONGATED HYPOCOTYL3 (FHY3) and FAR-RED IMPAIRED RESPONSE1 (FAR1) as inhibitors of flowering in phytochrome A signaling pathway. miR156-targeted SQUAMOSA PROMOTER BINDING PROTEIN LIKE (SPL) genes are involved in transition from juvenile to adult phase and promote flowering. In this […]
