abscisic acid - 2024 PLAYTIME

Question

Sean Cutler has shown how this molecule helps certain organisms deal with drought stress. For 10 points each:

[10m] Name this isoprenoid hormone mimicked by the synthetic sulfon·amide pyrabactin. This hormone causes guard cells to shrink to reduce transpiration, and it works against gibberellin to maintain dormancy.

ANSWER: abscisic acid [or ABA; or abscisin II]

[10e] Abscisic acid inhibits this process, in which water fills the seed through imbibition, and amylase breaks down the endosperm layer. This process results in a plant embryo emerging from the seed.

ANSWER: germination [or word forms like germinating; or sprouting]

[10h] During germination, this part of the plant embryo is the first to emerge. This structure below the hypocotyl grows downward to become the root and is contrasted with the plumule.

ANSWER: radicle
