Why does telomere length vary in plants?

Choi et al. uncover the association between telomere length and flowering time variation in Arabidopsis, rice, and maize. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab022   Background: Telomeres are DNA-protein complexes found at the ends of eukaryotic chromosomes that protect the…

TERMINAL FLOWER 1-FD complex target genes and competition with FLOWERING LOCUS T (Nat. Commun.)

The onset of reproductive development is tightly regulated in response to environmental cues as early and delayed flowering greatly affects seed production. In Arabidopsis, the timing of flower formation is controlled by members of the Phosphatidyl Ethanolamine-Binding Protein (PEBP) family: TERMINAL…

Exploring variation in a key maize regulator of floral form

María Jazmín Abraham-Juárez, Amanda Schrager-Lavelle et. al. explore how variation in a key floral regulator affects floral development, downstream gene expression and protein complex assembly in maize. Plant Cell https://doi.org/10.1105/tpc.20.00300  by Jazmin Abraham-Juarez, Biology Department,…

Cuscuta australis (dodder) parasite eavesdrops on the host plants’ FT signals to flower (PNAS)

Plants sense environmental cues, such as day length, to induce flowering and successfully reproduce. An important mobile regulator of flowering is FLOWERING LOCUS T (FT). Upon floral induction, FT is transported from the leaves to the shoot apical meristem where it triggers flower development. Dodders…
