Consistently, these three families of TFs appear to play important roles in drought stress signalling [35–37].. Comparison of lncRNA transcripts under drought stress Similarly, (2XDR_vs._2XCK) vs. 1, 69 DE lncRNAs were specific to drought-stressed 4× leaves (Fig. Table 2 Changes in differentially expressed genes involved in photosynthesis in 2× and 4× cassava leaves under drought stress conditions.

In addition, the results showed a decrease in the mean values of stomatal. length in the sugarcane cultivars under stressed conditions compared to the control. Similar results were observed by Meng et al. Zhou (2008) in which stomatal density was negatively correlated with stomatal length under different drought stress conditions. However, Yang et al.

In case of heat stress photosynthetic rate of Russet Burbank wild type plants decreased up to 39% and a 70% decrease of heat and drought stress after 12 days compared to their control plants at the same time point, while transgenic Novel_105 Russet Burbank plants showed a 13% increase in response to heat stress and a 55% decrease with the exposure of combined heat and drought stress conditions in the same comparison.

Moreover, soluble sugar (SS) substan- tially increased after simulated drought stress and then gradually decreased from 6 h to 12 h, but the SS contents at 6 and 12 h were still higher than those in the control (Fig. 3 The MA plot to display the different expressed genes in leaves of Pterocarya stenoptera after 3 h (a) and 12 h (b) exposure to drought stress conditions when FC ≥ 1.5.

A similar trend in both white clover cultivars to drought stress or thiamin was observed for this attribute.. A significant reduction (P ≤ 0.001) was observed in total soluble proteins in both white clover cultivars under both water deficit conditions. Foliar applications of thiamin had a negligible effect on the accumulation of total soluble proteins in both white clover cultivars under drought stress conditions.

In total, 2044 genes were transcriptionally affected by the MtPHD6 transgene or drought treatment (Additional file 3: Table S3).. under control and drought stress conditions, respect- ively. In WT plants, drought stress treatment modulated expression of 1231 genes, including 950 up-regulated and 281 down-regulated genes. Comparatively, signifi- cantly fewer DEGs were identified by drought stress treatment in MtPHD6 OE lines, with 683 up-regulated genes and 465 down-regulated genes (Fig.

After the shoots were grown in the climate chamber for 4 weeks, their responses to the stress conditions were examined.. The effects of drought stress treatments on the number of shoots and chlorophyll contents in the 15 different genotypes were presented in Table 1. In the study, it was. determined that the number of shoots in all genotypes decreased significantly as compared to the control treatment in response to the increase in the level of drought stress.

The performance of T1, T2, and T3 genotypes against drought stress were evaluated to determine whether the BADH expression enhances drought tolerance of white clover. After drought stress, the BADH transcript levels in T1, T2, and T3 genotypes significantly increased (Figure 4a). Moreover, after the drought stress, GB contents of the leaves of T1, T2, and T3 genotypes significantly increased, compared to nonstress conditions.

Principal component analysis (PCA) showed that the first two PCs with eigenvalues >1 had more than 50% of the total variability among the mutant lines under normal and water limited conditions. Cluster analysis depicted that considerable variations existed among all mutant lines. Using drought tolerance indices (Stress tolerance index and geometric mean productivity), high yielding mutant lines under drought stress were selected.

response to drought stress. Background: Drought is one of the most adverse environmental factors limiting crop productions and it is important to identify key genetic determinants for food safety. In our previous study, abundance of the wheat CPK34 (TaCPK34) protein was remarkably upregulated in wheat plants suffering from drought stress, inferring that it could be involved in this stress. Therefore, here we further detected its function and mechanism in response to drought stress..
