Which gene is Arabidopsis homolog of Antirrhinum FLO?
Correct option is B, LFY. In ABCE & ABCDE MODEL +Synapdrgon flowering problems like this, the accurate statement is LFY; the others are common mix-ups. Not these: A) AP1; C) AG; D) PI. Tissue transport questions usually turn on xylem vs phloem, living vs dead cells, or source vs sink.
