}Cytokinins are involved in many aspects of plant growth and development, and physiological evidence also indicates that they have a role in floral transition. In order to integrate these phytohormones into the current knowledge of genetically defined molecular pathways to flowering, we performed exogenous treatments of adult wild type and mutant Arabidopsis plants, and analysed the expression of candidate genes. We used a hydroponic system that enables synchronous growth and flowering of…

Elevated Levels of MYB30 in the Phloem Accelerate Flowering in Arabidopsis through the Regulation of FLOWERING LOCUS T
- Environmental SciencePloS one

Increased levels of MYB30, which was reported to be induced in response to the perception of pathogens, can accelerate flowering and MyB30 may be a candidate to mediate cross-talk between gene networks involved in biotic stress perception and flowering time.

It is shown that the pep1 mutant exhibits an elongated-stem phenotype, similar to that caused by treatment with exogenous GA, consistent with PEP1 repressing GA responses, and the down-regulation of PEP2 likely increases GA sensitivity, and GA responses contribute to determining the length of vernalization required for flowering and reproduction.

By transposon tagging, late flowering agl20 mutants are identified and it is shown that AGL20 is involved in flowering time control and integrates signals of different pathways of floral induction and might be a central component for the induction of flowering.

It is shown that FT and the closely related TSF are not essential for flowering, but that the double mutant is photoperiod-insensitive, and that TSF and FT have similar biochemical functions by showing that they interact in yeast with the same bZIP transcription factors.

It is proposed that FT functions through partner-dependent transcriptional activation of these and as-yet-unknown genes and that this occurs at several sites and that organ fate may depend on both degree of activation and the developmental stage reached by the organ before activation occurs.

It is found that the failure of gibberellin-deficient ga1-3 mutants to flower in short days was paralleled by the absence of LEAFY promoter induction, and a causal connection between these two events was confirmed by the ability of a constitutively expressed LEAFy transgene to restore flowering to ga1 -3 mutants in shortDays.
