Potato StCONSTANS-like1 Suppresses Storage Organ Formation by Directly Activating the FT-like StSP5G Repressor
The CONSTANS-FT pathway defines a core module for reproductive transition in both long-day (LD) and short-day (SD) plants. Changes in the transcriptional function of the CONSTANS (CO) protein have been proposed to mediate differential SD activation of FLOWERING LOCUS T (FT) orthologs in SD plants. Potato Andigena genotypes have an obligate SD requirement for tuber formation, and this photoperio...
متن کاملFlower Development: From Bud to Bloom
In many commercial cut flowers, particularly those with spike or compound inflorescences, postharvest life and quality are highly dependent on the continued development of small buds to open blooms. Buds may be separated into two major types – those enclosed by a calyx, where petal growth is largely complete before the calyx opens or is shed, and those where the petals are naked and expand rapi...
متن کاملThe Multiple Signals That Control Tuber Formation1[OPEN]
Under optimum environmental conditions, tuberization in potato (Solanum tuberosum) is activated by signals that either function in the leaf or arise in this organ and move down into stolon tips to induce tuber formation. Three major signals have been identified: CYCLING DOF FACTOR1 (StCDF1) for earliness and StBEL5 mRNA and SELF-PRUNING6A (StSP6A) protein as mobile signals originating in the le...
متن کاملGraft-transmissible induction of potato tuberization by the microRNA miR172.
The photoreceptor phytochrome B (PHYB) and the homeodomain protein BEL5 are involved in the response of potato tuber induction to the photoperiod. However, whether they act in the same tuberization pathway is unknown. Here we show the effect of a microRNA, miR172, on this developmental event. miR172 levels are higher under tuber-inducing short days than under non-inductive long days and are upr...
متن کاملControl of photoperiod-regulated tuberization in potato by the Arabidopsis flowering-time gene CONSTANS.
Photoperiod controls several responses throughout the plant life cycle, like germination, flowering, tuber formation, onset of bud dormancy, leaf abscission, and cambium activity. From these processes, flowering has been most extensively studied, especially in Arabidopsis thaliana. Photoperiod sensing by the function of photoreceptors and the circadian clock appears to regulate flowering time v...
