Submergence and drought are major constraints to rice (Oryza sativa) production in rain-fed farmlands, both of which can occur sequentially during a single crop cycle. SUB1A, an ERF transcription factor found in limited rice accessions, dampens ethylene production and gibberellic acid responsiveness during submergence, economizing carbohydrate reserves and significantly prolonging endurance. He...

supplementary irrigation is a key factor in dryland production of lentil (lens culinaris medik.). in order to study the effects of supplementary irrigation on phenological and morphological characters of three lentil (lens culinaris medik.) cultivars, a trial carried out as split block based on randomized complete block design with three replications at research field of agricultural college, f...

in order to further understand the emergence and germination of sugar beet monogerm cultivars under moisture stress, the current study was carried out at three stages. at the first stage, the quality of germination of three monogerm cultivars (rizofort, rasoul and zarghan) were studied under five moisture stress levels (0, -2, -4, -6 and -8 bars) in germinator at 15°c by between-paper method. a...

the possible alleviating effects of salicylic acid on protection of cowpea (vigna unguiculata) cv. parastu under water stress conditions were investigated in the university of zanjan agriculture research station during 2008. water stress was imposed by withholding irrigation at 50% flowering (flowering water stress, fws) and when 50% of the pods grew 2-3cm (pod-formation water stress, pfws). sa...

some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...

Plants have evolved to have sophisticated adaptation mechanisms to cope with drought stress by reprograming transcriptional networks through drought responsive transcription factors. NAM, ATAF1-2, and CUC2 (NAC) transcription factors are known to be associated with various developmental processes and stress tolerance. In this study, we functionally characterized the rice drought responsive tran...

range forage of vicia variabilis, astragalus spp., medicago sativa, prangos uloptera and sanguisorba minor was sampled during three phenological stages from the controlled rangeland stations in chaharmahal and bakhtiari province, iran. samples were analyzed for the determination of crude protein (cp%), ether extract (ee), crude fiber (cf), total ash, neutral detergent fiber (ndf), acid detergen...

Thymus hyemalis L. and Spanish Thymus vulgaris L. shrubs are characterized by a large chemical intraspecific variability among he plants. This fact makes it difficult to detect real changes occurring in their essential oil composition during the vegetative cycle. ased on this, the clones of T. hyemalis and Spanish T. vulgaris were used in this present work to monitor seasonal variations in the ...
