Plant Physiology

For each of the following, indicate the appropriate hormone (auxin, gibberellin, ABA, cytokinin, ethylene). There may be more than one correct answer for some questions.

	amounts that stimulate shoot growth inhibits roots
	delays senescence
	derived from a catabolic pathway
	diterpene
	fattens cells
	first detected in foolish seedling disease
	first observed because of aberrant growth of rice
	forms bound complexes with glucose or other compounds
	found in commercial rooting preparations
	benzyladenine has a similar activity
	basipetal transport
	associated with crown gall formation
	active in phototropism and gravitropism
	first discovered by Frits Went in bending of oat coleoptiles
	gas
	important in embryogenesis
	involved in leaf abscission
	planar ring with 0.5 nm charge separation polar transport
	promotes fruit ripening
	promotes senescence
	obtained from coconut milk
	more than 100 types known
	maintains dormancy
	involved in witches broom formation
	involved in thigmomorphogenesis
	related to the climacteric
	responsible for epinasty
	silver ions inhibit actions
	some think they may be made by bacteria rather than plants
	split pea curvature test
	stimulates conversion of etioplasts into chloroplasts
	stimulates dicot cotyledon expansion
	stimulates ethylene synthesis
	used in malting industry
	stimulate root initiation
	associated with the anticodon region of tRNA
	derived from Greek word meaning "to grow"
	2,4-D is a synthetic version
	tri-iodobenzoic acid (TIBA) inhibits transport of this hormone
	results in short, fat and stupid seedlings
	helps provide embryo with desiccation tolerance

	controls morphogenesis of plant tissue cultures
	derived from carotenes (tetraterpenes)
	dioxin is a byproduct of the manufacture of these hormone analogs
	apples are a rich source of this hormone
	closes stomata
	chemically similar to nucleotide in DNA
	causes loosening of the cell wall
	carbon dioxide inhibits many actions
	occurs as free base, nucleoside, nucleotide
	breaks dormancy in seeds and buds
	bolting
	biosynthesized from tryptophan
	coconut milk is a rich source
	coded by two genes on the Ti plasmid
	indole ring
	involved in apical dominance
	promotes flowering of pineapples
	prevents vivipary
	promotes stem elongation in intact plants
	parthenocarpic fruit development
	often antagonistic to effects of ABA
	napthalene acetic acid has similar activity
	molecule with 4 or 5 rings
	methionine is the amino acid precursor
	HCN produced during biosynthesis
	reverses dwarfing in some plants
	reverses juvenility in ivy
	stimulates a membrane-bound proton pump
	stimulates amylase production in cereal grains
	stimulates cell elongation
	stimulates seed germination
	synthesis is stimulated by wounding
	terpene
	triple response
	stimulates coleoptile/shoot elongation but inhibits root growth
	used to increase size and spacing in grapes
	sesquiterpene
	affects sex expression in plants
	about 40 different structures are known
	AMO1618 inhibits synthesis
	one bad apple spoils the whole bunch
