FLOWERING LOCUS C influences the timing of shoot maturation in Arabidopsis thaliana.
Many plant species undergo changes in leaf morphology as the vegetative shoot meristem matures (Poethig, 2003; Telfer et al., 1997). In Arabidopsis, juvenile leaves are produced before shoot maturation and are relatively round and lack trichomes on the abaxial side (underside) of the leaves. Adult leaves formed after the shoot meristem matures are more elliptical and have abaxial trichomes. An ...
متن کاملmiR824-Regulated AGAMOUS-LIKE16 Contributes to Flowering Time Repression in Arabidopsis.
The timing of flowering is pivotal for maximizing reproductive success under fluctuating environmental conditions. Flowering time is tightly controlled by complex genetic networks that integrate endogenous and exogenous cues, such as light, temperature, photoperiod, and hormones. Here, we show that AGAMOUS-LIKE16 (AGL16) and its negative regulator microRNA824 (miR824) control flowering time in ...
متن کاملMultiple paths to similar germination behavior in Arabidopsis thaliana.
Germination timing influences plant fitness, and its sensitivity to temperature may cause it to change as climate shifts. These changes are likely to be complex because temperatures that occur during seed maturation and temperatures that occur post-dispersal interact to define germination timing. We used the model organism Arabidopsis thaliana to determine how flowering time (which defines seed...
متن کاملMajor flowering time gene, flowering locus C, regulates seed germination in Arabidopsis thaliana.
Flowering locus C (FLC) is a major regulator of flowering responses to seasonal environmental factors. Here, we document that FLC also regulates another major life-history transition-seed germination, and that natural variation at the FLC locus and in FLC expression is associated with natural variation in temperature-dependent germination. FLC-mediated germination acts through additional genes ...
متن کاملPolycomb-Group Proteins and FLOWERING LOCUS T Maintain Commitment to Flowering in Arabidopsis thaliana.
The switch from vegetative to reproductive growth is extremely stable even if plants are only transiently exposed to environmental stimuli that trigger flowering. In the photoperiodic pathway, a mobile signal, florigen, encoded by FLOWERING LOCUS T (FT) in Arabidopsis thaliana, induces flowering. Because FT activity in leaves is not maintained after transient photoperiodic induction, the molecu...
