DELLA degradation by gibberellin promotes flowering via GAF1-TPR-dependent repression of floral repressors in Arabidopsis (Plant Cell)
Plant Science Research WeeklyIn Arabidopsis, flowering is promoted by the activation of the florigen FT in response to long days and by the accumulation of the phytohormone GA under short days (SD). Despite the extensive knowledge of regulatory networks involving FT, the molecular mechanism controlled by GA is still unresolved.…
Pollen PCP-B peptides unlock a stigma peptide–receptor kinase gating mechanism for pollination (Science)
Plant Science Research WeeklyIt’s spring where I live and the air and my eyes are filled with pollen. The lucky few pollen grains that land on the stigmatic surface of a flower might germinate and deliver the sperm to the ovule, but there are many checkpoints even after their safe landing. Here, Liu et al. uncover one of the earliest…
SeedQuant: A deep learning-based tool for assessing stimulant and inhibitor activity on root parasitic seeds (Plant Physiol.)
Plant Science Research WeeklyParasitic plants can completely wipe out a farmer’s harvest. The seeds can lie dormant in soil until they perceive signals from potential host plants, which stimulate germination. Therefore, germination stimulants applied to fields before the crops are planted can cause the parasitic seeds to germinate…

WWR Full PostReview: Ageing beautifully: can the benefits of seed priming be separated from a reduced lifespan trade-off?
Seed priming is a family of presowing techniques that control water uptake in seeds, so they are dehydrated once metabolic activities have restarted but before the end of germination. Primed…

How algae adjust light harvesting efficiency to the prevailing supply of CO2
The Plant Cell: In a NutshellOlga Blifernez-Klassen and colleagues identify a minimal NAB1 promoter that confers responsiveness to low CO2 supply and the transcription factor LCRF that mediates NAB1 upregulation.
