Effects of nitrogen and irrigation interval on broomrape (Orbanche aegyptiaca) damage reduction in host plant (Cucumis sativa L.)

In order to study the effects of nitrogen and irrigation interval on broomrape (Orbanche aegyptiaca) damage reduction in cucumber (Cucumis sativa L.), an experiment with two factors, nitrogen (100, 200 and 300 Kg/ha) and irrigation interval (3, 6 and 9 day), in three replications was performed in the greenhouse of Northern Khorasan Agricultural and Natural Resource Research Center. The results obtained show that the...

Effect of lead and nickel toxicity on chlorophyll and proline content of Urd (Vigna mungo L.) seedlings

The effect of Pb and Ni on chlorophyll a, b, carotenoids and proline content of Black gram (Vigna mungo L.) seedlings were evaluated under 10, 50 and 100 µM concentration. These concentrations significantly affected chlorophyll, carotenoid and proline content of Black gram as compared to control. Pb and Ni at 10 µM concentration resulted in less significant effect on chlorophyll, a, b and carotenoids....

Induction of a C-repeat binding factor gene by calcium to resist low temperature stress in rice

Adaptation to stress is an important phenomenon in plants. C–repeat binding factor (CBF), an Apetela 2 domain transcriptional activator, helps the plant in combating cold stress. Here, we cloned and purified a CBF family gene (OsDREB1B) from Oryza sativa. This gene (OsDREB1B) is induced by calcium in absence of cold. The bioinformatics analysis reveals that the induction of OsDREB1B is probably mediated...
