Flowering time pathway

WebSep 2, 2003 · Flowering time control in plants involves integration of multiple signals. One of the signalling pathways in Arabidopsis involves a negative autoregulatory loop, in which the FCA protein together with FY promotes the choice of an alternative polyadenylation site within the FCA pre-mRNA to produce a transcript that does not encode a functional protein. WebHowever, the regulatory pathway of GI affecting flowering time is unknown in maize. Here, we identified that the zmgi2 mutant flowered earlier than the wild type under long day (LD) conditions, whereas the difference in flowering time was not apparent under short day (SD) conditions. The 24h optimal expression of the gene in the stem apex ...
