Abstract The natriuretic peptides (NP) are vertebrate hormones involved in the regulation of ion and water homeostasis in the cell. In plants, natriuretic peptides (PNP) have been identified by molecular and biochemical methods. It has been suggested that PNPs, have similar functions to the PN, since they mediate (1) ion transport through the cell, (2) the opening and closing of Na⁺ and K⁺ channels through the stimulation and synthesis of a second messenger such as cGMP, and (3) the aperture of stomata. In this study, a PNPs gene was partially identified by PCR in garlic (Allium sativum L.), which was called… More >

Abstract Two experiments were performed in 2011-2012 to investigate the response of three oilseed rape cultivars to drought stress, grown under two climate conditions in Iran (cold and hot climates). The experiments were conducted using a randomized complete-block design arranged in split-plot with three replicates. The irrigation treatments (FI: full irrigation; WIF: withholding irrigation at flowering stage, and WIS: withholding irrigation at the silique formation stage until physiological maturity) were allocated to main plots, whereas subplots consisted of the oilseed rape cultivars: early maturating (GKH2005), relatively late maturing (Opera) and late maturing (Okapi). Drought caused a significant reduction in seed number,… More >
