Soil salinity and drought are the two most common and frequently co-occurring abiotic stresses constraining crop growth and productivity. Greenhouse pot experiments were conducted to investigate the tolerance potential and mechanisms of Tibetan wild barley genotypes (XZ5, drought-tolerant; XZ16, salinity/aluminum tolerant) during anthesis compared with(More)
To reveal grain physio-chemical and proteomic differences between two barley genotypes, Zhenong8 and W6nk2 of high- and low-grain-Cd-accumulation, grain profiles of ultrastructure, amino acid and proteins were compared. Results showed that W6nk2 possesses significantly lower protein content, with hordein depicting the greatest genotypic difference, compared(More)
A hydroponic experiment was carried out to study the physiological mechanisms of N-acetyl cysteine (NAC) in mitigating cadmium (Cd) toxicity in two barley (Hordeum vulgare L.) genotypes, Dong 17 (Cd-sensitive) and Weisuobuzhi (Cd-tolerant). Addition of 200 μM NAC to a culture medium containing 5 μM Cd (Cd + NAC) markedly alleviated Cd-induced growth(More)
Aluminum (Al) toxicity is a major limiting factor for plant production in acid soils. Wild barley germplasm is rich in genetic diversity and may provide elite genes for crop Al tolerance improvement. The hydroponic-experiments were performed to compare proteomic and transcriptional characteristics of two contrasting Tibetan wild barley genotypes Al-(More)
Cadmium (Cd) is a severe detrimental environmental pollutant. To adapt to Cd-induced deleterious effects, plants have evolved sophisticated defence mechanisms. In this study, a genome-wide transcriptome analysis was performed to identify the mechanisms of Cd tolerance using two barley genotypes with distinct Cd tolerance. Microarray expression profiling(More)
Greenhouse pot experiments were conducted using Cd-tolerant (Bing97252) and sensitive (Xiushui63) rice genotypes to investigate genotypic differences in yield, Cd accumulation and photosynthesis at different growth stages in response to different Cd levels and as affected by glutathione (GSH). Yield of the two genotypes were impaired when soil Cd levels(More)
A hydroponic experiment was conducted to study the ameliorative effects of separate or combined application of exogenous glutathione (GSH), selenium (Se) and zinc (Zn) upon 20 μM cadmium (Cd) plus 20 μM chromium (Cr) heavy metal stress (HM) in rice seedlings. The results showed that HM caused a marked reduction in seedling height, chlorophyll content (SPAD)(More)
Greenhouse hydroponic experiments were performed to investigate the effect of the foliar application of betaine on the growth and physiological traits of maize seedlings in a setting of cadmium (Cd) toxicity. The foliar application of 500 μM betaine for maize exposed to culture medium containing 50 μM Cd significantly alleviated Cd-induced growth inhibition(More)
Tobacco (Nicotiana tabacum L.) is more acclimated to cadmium (Cd) uptake and preferentially enriches Cd in leaves than other crops. MicroRNAs (miRNAs) play crucial roles in regulating expression of various stress response genes in plants. However, genome-wide expression of miRNAs and their target genes in response to Cd stress in tobacco are still unknown.(More)
Combined stress of salinity and heavy metal is a serious problem for crop production; however, physiological mechanisms of tolerance to such condition remain elusive in cotton. Here, we used two cotton genotypes differing in salt tolerance, to understand their response to salinity (NaCl) and cadmium (Cd) either alone or in combination (Cd + Na) via(More)
