“…The cooperating influences of environmental temperatures on growth and physiological attributes of Pisum sativum were investigated by Martel and Qaderi (2016), and found that higher temperatures and supplemental UV-B radiation significantly reduced the plant growth rate by decreasing stem height, diameter, and leaf area [35]. The findings were in agreement with earlier reports on crops, including canola [36] and peas [37] as well as some higher plants [38].…”

The present study investigated the influences of different day and night temperature regimes on the growth of violet rape (Brassica rapa var. chinensis) and pinpointed the optimal temperature combination for both yield and quality of the plant. For this purpose, the plants were grown under 6 temperature combination conditions: W1 (30/20ºC, 12-h light/12-h dark), W2 (25/15ºC, 12-h light/12-h dark), W3 (20/10ºC, 12-h light/12-h dark), W4 (30/15°C, 12-h light/12-h dark), W5 (25/10ºC, 12-h light/12-h dark), and W6 (30/10ºC, 12-h light/12-h dark), and in addition we measured various morphological, yield, and biochemical traits. Results demonstrated that temperature regimes considerably affected the growth parameters of the violet rape compared with control. The W3 treatment with an average temperature of 20/10ºC displayed the highest plant growth traits, including plant height (12.74±0.24 cm), leaf length (8.20±0.08 cm), leaf width (5.44±0.16 cm), and leaf area (33.46±0.83 cm²). Moreover, a highly significant correlation (p<0.05) was found between temperature and soluble protein, chlorophyll, anthocyanin, nitrate nitrogen contents, and root activity; whereas the vitamin C and soluble sugar contents remained significantly unaffected except in the W1 treatment, under different temperature combinations between day and night. This study concluded that high temperature exerts an adverse effect on plant growth, and therefore a low day and night temperature combination is suggested in order to achieve high yield and quality for irrigated violet rape.

“…These results indicated that it was possible that MBF1c modulates heat tolerance through controlling the SA concentration in grape. In addition, SA was recently proposed to play an important role in thermotolerance in other plant species (Larkindale and Knight, 2002;Martel and Qaderi, 2016). Previous studies have shown that HSFs play an important role in thermotolerance in plants and other organisms, regulating HSPs as well as different acclimation and detoxification proteins (von .…”

Integrating Omics and Alternative Splicing Reveals Insights into Grape Response to High Temperature

Heat stress is one of the primary abiotic stresses that limit crop production. Grape (Vitis vinifera) is a cultivated fruit with high economic value throughout the world, with its growth and development often influenced by high temperature. Alternative splicing (AS) is a widespread phenomenon increasing transcriptome and proteome diversity. We conducted high-temperature treatments (35°C, 40°C, and 45°C) on grapevines and assessed transcriptomic (especially AS) and proteomic changes in leaves. We found that nearly 70% of the genes were alternatively spliced under high temperature. Intron retention (IR), exon skipping, and alternative donor/acceptor sites were markedly induced under different high temperatures. Among all differential AS events, IR was the most abundant up-and down-regulated event. Moreover, the occurrence frequency of IR events at 40°C and 45°C was far higher than at 35°C. These results indicated that AS, especially IR, is an important posttranscriptional regulatory event during grape leaf responses to high temperature. Proteomic analysis showed that protein levels of the RNA-binding proteins SR45, SR30, and SR34 and the nuclear ribonucleic protein U1A gradually rose as ambient temperature increased, which revealed a reason why AS events occurred more frequently under high temperature. After integrating transcriptomic and proteomic data, we found that heat shock proteins and some important transcription factors such as MULTIPROTEIN BRIDGING FACTOR1c and HEAT SHOCK TRANSCRIPTION FACTOR A2 were involved mainly in heat tolerance in grape through up-regulating transcriptional (especially modulated by AS) and translational levels. To our knowledge, these results provide the first evidence for grape leaf responses to high temperature at simultaneous transcriptional, posttranscriptional, and translational levels.Heat stress is one of the main abiotic stresses limiting crop production worldwide. Global warming is predicted to be accompanied by more frequent and powerful extreme temperature events (Lobell et al., 2008). Therefore, a better understanding of the response of plants to heat stress is essential for improving their heat tolerance. In general, heat stress is a complex function of intensity (temperature in degrees), duration, and rate of increase in temperature. At very high temperatures, a catastrophic collapse of cellular organization may occur within minutes, which results in severe cellular injury and even cell death (Wahid et al., 2007). At moderately high temperatures, direct injuries include protein denaturation and aggregation and the increased fluidity of membrane lipids. Indirect or slower heat injuries include inactivation of enzymes, inhibition of protein synthesis, protein degradation, and loss of membrane integrity. These injuries eventually lead to a decline of net photosynthetic rate, reduced ion flux, production of toxic compounds and reactive oxygen species, and inhibition of growth. Actually, plants are not passively damaged by heat stress but respond to temperature changes by r...

“…However, plants have developed sophisticated mechanisms to tolerate abiotic stress, such as plant hormones: these are small organic molecules that act as signals to the plant in its growth, differentiation and development (Davies, 2010). Recently there has been emphasis on new hormonal classes, such as brassinosteroids and SA, both of which have already been explored as potential bioregulators for the attenuation of plant stress by activating protective responses in plants submitted to different abiotic stresses, such as: soil salinity (Misra and Saxena, 2009;Javid et al, 2011), drought (Arivalagan and Somasundaram, 2016;Jangid and Dwivedi, 2017) and temperature (Martel and Qaderi, 2016).…”

The aim of this study was to evaluate the potential use of two bioregulators, 24-epibrassinolide (BR) and salicylic acid (SA), as attenuators of drought stress on common bean plants (Phaseolus vulgaris L.). This was done by subjecting the plants to three different soil moisture levels, and then analyzing: gas exchange by the leaves, enzymes of antioxidant metabolism (superoxide dismutase, catalase and ascorbate peroxidase), total soluble protein content, photosynthetic pigments, relative leaf water content, and biometric parameters. Neither SA nor BR had significant effects on the parameters of gas exchange and photosynthetic pigments, but they helped to regulate the levels of hydrogen peroxide in the plants, by adjusting both ascorbate peroxidase activity and catalase activity. Therefore, SA and BR are considered to be useful treatments for increasing tolerance to water stress in common bean plants, because their use caused improvements in the plants’ protective mechanisms against drought stress, without any detrimental side effects.
