Dark Reversion of Phytochrome in Sinapis alba L.
Phytochrome in Sinapis alba L. (white mustard) seedlings undergoes both decay and reversion after an exposure to red light. This is typical of other crucifers and of dicotyledons in general. In the presence of sodium azide, decay is inhibited, and reversion continues at about the same rate as in buffer alone. The reversion has been demonstrated both in cotyledon plus hypocotyl hook and in hypoc...

متن کاملExperimental insights on the function of ancillary pollen and stigma polymorphisms in plants with heteromorphic incompatibility.
Most heterostylous plants possess a reciprocal arrangement of stigmas and anthers (reciprocal herkogamy), heteromorphic self-incompatibility, and ancillary polymorphisms of pollen and stigmas. The topographical complementarity hypothesis proposes that ancillary polymorphisms function in the rejection of incompatible pollen thus promoting disassortative pollination. Here, we test this hypothesis...
متن کاملSelf-incompatibility in the Iranian Almond Cultivar ‘Mamaei’ Using Pollen Tube Growth, Fruit Set and PCR Technique
Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...
متن کاملInteraction Between Cadmium Stress and Sulphur Nutrition Level on Macronutrient Status of Sinapis alba L.
This study evaluated the possibility of improving the macronutrient status of Cd-stressed white mustard 'Rota' using intensive S nutrition. Three S-SO4 (2, 6, 9 mM S) and four CdCl2 doses (0, 0.0002, 0.02, 0.04 mM Cd) in the Hoagland's nutrient solution were conducted for 14 days. High S supply (6 or 9 mM) appears, to some extent, to affect positively the macronutrient status of Cd-stressed mus...
