Drought is one of the most frequent abiotic stresses limiting the productivity and geographical distribution of sugarcane culture. The use of drought-tolerant genotypes is one approach for overcoming the effects of water stress. We conducted a comparative study to identify gene expression profiles under water stress in tolerant sugarcane roots. Two different cultivars, 1 drought tolerant (RB867...

Drought is an important factor limiting crop production in arid and semi-arid conditions. Drought indices which provide a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions. Ten barle...

Cd-tolerant and Cd-sensitive rice cultivars were used to study the role of NH4 + accumulation in Cd-induced toxicity. NH4 + accumulation seems to be involved in regulating the toxicity of rice seedlings caused by CdCl2. This conclusion was based on the observations that (a) on treatment with CdCl2, NH4 + content increased rapidly in the leaves of the Cd-sensitive cultivar (cv. Taichung Native 1...

Involvement of 26S proteasomal subunits in plant pathogen-interactions, and the roles of each subunit in independently modulating the activity of many intra- and inter-cellular regulators controlling physiological and defense responses of a plant were well reported. In this regard, we aimed to functionally characterize a Solanum lycopersicum 26S proteasomal subunit RPT4a (SlRPT4) gene, which wa...

The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘S...

a breeding program was started in safiabad agricultural research center in 1999, to produce an improved maize hybrid with a relative heat stress tolerance. consequently at 2005 a few s6 lines with having moderately tolerance to high temperature were obtained. these combinates were then evaluated for three consecutive years in three sub-tropical regions of the country includes khzestan, ilam and...

BACKGROUND AND AIMS Soil phosphorus (P) solubility declines sharply when a flooded soil drains, and an important component of rice (Oryza sativa) adaptation to rainfed lowland environments is the ability to absorb and utilize P under such conditions. The aim of this study was to test the hypothesis that rice cultivars differ in their P responses between water regimes because P uptake mechanisms...

Plant salt tolerance is associated with a high rate of root growth. Although growth governed by cell wall and apoplastic pH, the relationship between these factors in elongation zone under salinity stress remains unclear. Herein, we assess pH- expansin-dependent extensibility, expansin expression salt-sensitive (Yongliang-15) -tolerant (JS-7) cultivars stress. A six-day 80 mM NaCl treatment sig...
