Transcriptional networks controlling plant development.
The rise of developmental biology to the fore of modern biology can be traced back to the efforts of three people: Ed Lewis, Christiane Nüsslein-Volhard, and Eric Wieschaus. Lewis had been studying the homeotic Bithorax gene complex in fruitfly (Drosophila melanogaster) for several decades and came to the conclusion that the genes in this complex control body pattern along the anterior-posterio...
متن کاملLight control of plant development.
To grow and develop optimally, all organisms need to perceive and process information from both their biotic and abiotic surroundings. A particularly important environmental cue is light, to which organisms respond in many different ways. Because they are photosynthetic and non-motile, plants need to be especially plastic in response to their light environment. The diverse responses of plants t...
متن کاملEthylene, light, and anthocyanin synthesis.
Ethylene control of anthocyanin formation functions only through light-initiated synthesis pathways of the rapid synthesis phase. Treatment with ethylene in the dark had no effect on dark anthocyanin synthesis in red cabbage (Brassica oleracea L.). Pretreatment of both red cabbage and sorghum (Sorghum vulgare L.) with ethylene for 24 hours in the dark did increase the rate of synthesis when the...
متن کاملEthylene Signaling Influences Light-Regulated Development in Pea.
Plant responses to light involve a complex network of interactions among multiple plant hormones. In a screen for mutants showing altered photomorphogenesis under red light, we identified a mutant with dramatically enhanced leaf expansion and delayed petal senescence. We show that this mutant exhibits reduced sensitivity to ethylene and carries a nonsense mutation in the single pea (Pisum sativ...
متن کاملAbscission: ethylene and light control.
The role of ethylene in light control of leaf abscission im mung bean, Vigna radiata (L.) Wilczek cv Jumbo, cuttings was examined. While red light inhibits and far-red light promotes loss of break strength in abscission zones as compared with dark controls, changes in the rate of abscission could not be associated with changes in the rate of ethylene production. Reducing ethylene synthesis in t...
