ˌphotomorphoˈgenesis Bot.
[f. photo- 1 + morphogenesis.]
(See quots. 1964.)
1959A. W. Galston in R. B. Withrow Photoperiodism ii. 139 Further knowledge of this substance..will help elucidate the details of photomorphogenesis. 1964Biol. Rev. XXXIX. 87 By the term photomorphogenesis we designate the control which may be exerted by visible radiation over growth, development and differentiation of a plant, independently of photosynthesis. Ibid. 506 Photomorphogenesis concerns the regulation of plant growth and morphology by light. 1975Nature 10 Jan. 94/2 Profound changes in the activity of many plant enzymes occur during photomorphogenesis, the response of dark-grown plants to light.
So ˌphotoˌmorphogeˈnetic, -ˈgenic adjs., of or pertaining to the effects of light on plants; ˌphotoˌmorphogeˈnetically, -ˈgenically advs.
1956Plant Physiol. XXXI. 279/1 This same reversible photoreaction was also established for the control of flower initiation of Xanthium..and photomorphogenic effects such as leaf expansion. 1959A. W. Galston in R. B. Withrow Photoperiodism ii. 139 We have been concerned with the photomorphogenic reaction and auxin metabolism. Ibid. 153 Certain experiments have suggested that the cofactor is transformed, by photomorphogenically active light, into the inhibitor. 1960Chem. Abstr. LIV. 25090 Some expts. indicated that V..is converted to I by photomorphogenetically active light. 1962Plant Physiol. XXXVII. 142 (heading) Photomorphogenetic responses of sporelings of Marsilea vestita. 1971Nature 27 Aug. 602/1 Acetylcholine, when given to dark grown seedlings, mimicked the effect of red light in certain photomorphogenic responses. 1975D. Vince-Prue Photoperiodism in Plants iv. 119 Some experiments suggest that..the photomorphogenetic response occurs because Pfr operates via a threshold type of mechanism. |
