Far-red light counteracts ZTL activity by decreasing ZTL abundance, increasing GI levels, and negatively affecting formation of the ZTL-GI complex in the morning.
Quoted textsource-backed
Far-red light counteracted ZTL activity by decreasing its abundance (possibly via phytochrome A (phyA)) while increasing GIGANTEA (GI) levels and negatively affecting the formation of the ZTL-GI complex in the morning.
ZTL interacts with TOEs and thereby represses morning FT expression in natural environments.
Quoted textsource-backed
Here, we demonstrate that ZEITLUPE (ZTL) interacts with the FT repressors TARGET OF EATs (TOEs), thereby repressing morning FT expression in natural environments.
Under natural long-day-mimicking conditions with simulated sunlight and daily temperature cycles, the ztl mutant shows high FT transcript levels specifically in the morning, and this pattern is mirrored in the toe1 toe2 double mutant.
Quoted textsource-backed
Under LDs with simulated sunlight (R:FR = 1.0) and daily temperature cycles, which are natural LD-mimicking environmental conditions, FT transcript levels in the ztl mutant were high specifically in the morning, a pattern that was mirrored in the toe1 toe2 double mutant.
Low night-to-morning temperatures increase the inhibitory effect of ZTL on morning FT expression by increasing ZTL protein levels early in the morning.
Quoted textsource-backed
Low night-to-morning temperatures increased the inhibitory effect of ZTL on morning FT expression by increasing ZTL protein levels early in the morning.
ZTL and LKP2 are not required for blue light-dependent CRY2 degradation.
