#flowering genes

4 public questions tagged with this topic.

Before vernalization, FLC expression is:

C fits best: High. Keep the VERNALIZATION & FLOWERING basics straight and High stands out as the precise answer. Avoid: A) Low; B) Absent; D) Oscillatory. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

LEAFY (LFY) gene is involved in:

Go with B — Floral meristem identity. Under PSS-Sec-E-Sensory biology, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Root meristem identity; C) Photomorphogenesis; D) Seed dormancy. When two options sound similar, choose the one that matches the textbook definition most tightly.

The FT–FD complex activates genes related to:

That points to B: Floral meristem identity. Compared with the other options, Floral meristem identity is the one that correctly describes the PSS-Sec-E-Sensory biology concept. The wrong ones are A) Root development; C) Leaf senescence; D) Phototropism. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

FT gene product functions as:

Pick B: Florigen. Thinking through PHOTOPERIODISM step by step rules out the lookalikes and leaves Florigen. Skip these: A) Photoreceptor; C) Repressor of flowering; D) Growth inhibitor. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.
