WebAbstract. Many plants use information about changing day length (photoperiod) to align their flowering time with seasonal changes to increase reproductive success. A … WebMay 4, 2024 · The chemical nature of florigen has been sought for decades. The most recent evidence suggests that at least one component is the protein encoded by the gene FLOWERING LOCUS T (FT). Due to florigen signaling, the entire plant will bloom even if only a part of one leaf is exposed to the correct photoperiod (Figure \(\PageIndex{3}\)).

WebJun 2, 2024 · Adjustment of flowering phenology to photoperiod-based seasonal cues in particular growth environments may have been a driving force for the expansion of cultivation areas toward higher and lower latitudes. To adapt to the northern parts of China, Korea, and Japan, soybean required reduced photoperiod sensitivity and early … WebFeb 13, 2004 · CO activity can be followed indirectly by measuring FT mRNA levels. The 35S::CO plants, which overexpress CO mRNA at constant levels independently of the circadian clock or exposure to light, contain FT mRNA at higher abundance during the photoperiod than in the dark (7, 8).A fusion of FT regulatory sequences to luciferase … The annual fluctuations in daylength that occur over much of the surface of our planet provide a reliable environmental cue regarding the time of year. It is not surprising, therefore, that the pathways that detect and promote flowering in response to photoperiod are among the most ancient and … See more Vernalization is defined as the process by which exposure to the cold of winter renders plants competent to flower (Kim et al., 2009).
