Rapid, organ-specific transcriptional responses to light regulate photomorphogenic development in dicot seedlings.
The dicotyledon seedling undergoes organ-specific photomorphogenic development when exposed to light. The cotyledons open and expand, the apical hook opens, and the hypocotyl ceases to elongate. Using the large and easily dissected seedlings of soybean (Glycine max 'Williams 82'), we show that genes involved in photosynthesis and its regulation dominate transcripts specific to the cotyledon, ev...
متن کاملLight-regulated gravitropism in seedling roots of maize.
Red light-induced changes in the gravitropism of roots of Zea mays variety Merit is a very low fluence response with a threshold of 10(-9) moles per square meter and is not reversible by far red light. Blue light also affects root gravitropism but the sensitivity of roots to blue is 50 to 100 times less than to an equal fluence of red. In Z. mays Merit we conclude that phytochrome is the sole...
متن کاملThe Frequencies of Seed and Seedling Abnormalities in Maize.
T HE fact that cross-fertilizing species carry relatively large numbers of deleterious recessives in a heterozygous condition has been demonstrated by various investigators and for several species. The results obtained have been used to make inferences or to provide a critical interpretation relative to population structure and size, types of gene action, mutation rates, selective advantage, an...

متن کاملResponses of Seed Germination, Seedling Growth, and Seed Yield Traits to Seed Pretreatment in Maize (Zea mays L.)
A series of seed priming experiments were conducted to test the effects of different pretreatment methods to seed germination, seedling growth, and seed yield traits in maize (Zea mays L.). Results indicated that the seeds primed by gibberellins (GA), NaCl, and polyethylene glycol (PEG) reagents showed a higher imbibitions rate compared to those primed with water. The final germination percenta...
