Special Issue Information

Dear Colleagues,

According to the last Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC), the anthropogenic greenhouse gas emissions have increased since the pre-industrial era, with CO2 as one of the main contributors. As a consequence, the warming of the climate system is unequivocal. Surface temperature is projected to rise over the 21st century under all assessed emission scenarios, and an increase in the frequency of extreme temperature events, such as heatwaves, is also very likely. Projected changes in rainfall patterns may involve a decrease in soil water availability in mid-latitude and subtropical dry regions, as well as increases in soil salinity. Abiotic stress factors associated with climate change exert adverse effects on crop physiology, such as limitation of growth and development, and alterations in plant phenology and crop quality. Within this context, the knowledge of the physiological responses of plants to multiple changing stress factors associated with climate change will help to the development of successful adaptation strategies to mitigate the impact of future environmental conditions on crops.

This Special Issue of Plants will analyze, from a multidisciplinary approach (ecophysiology, metabolomics, proteomics, transcriptomics, etc.) the impact of abiotic stresses associated with climate change on plant performance and crop quality. Contributions about adaptation strategies to climate change in agricultural crops and forest (from leaf to plant and canopy organizations levels) are also welcome.

The inexorable process of climate change in terms of the rise in minimum (nighttime) temperature delineates its huge impact on crop plants. It can affect the yield and quality of various crops. We investigated the effect of high night temperature (HNT) (+2.3 °C over ambient) from booting to physiological maturity on the yield parameters, grain growth rate (GGR), starch content, composition, and flour rheological properties in early (HI 1544, HI 1563) and late-maturing (HD 2932) wheat genotypes. The change in yield under HNT was highly correlated with grain number per plant (r = 0.740 ***) and hundred-grain weight (r = 0.628 **), although the reduction in grain weight was not significantly different. This was also reflected as an insignificant change in starch content (except in HI 1544). Under HNT, late-sown genotypes (HI 1563 and HD 2932) maintained high GGR compared to the timely sown (HI 1544) genotype during the early period of grain growth (5 to 10 days after anthesis), which declined during the later phase of grain development. The increased rheological properties under HNT can be attributed to a significant reduction in the amylose to amylopectin (AMY/AMP) ratio in early-maturity genotypes (HI 1544 and HI 1563). The AMY/AMP ratio was positively correlated to flour rheological parameters (except setback from peak) under HNT. Our study reports the HNT-induced change in the amylose/amylopectin ratio in early maturing wheat genotypes, which determines the stability of flour starches for specific end-use products.

Triticum aestivum L. cv. Gazul is a spring wheat widely cultivated in Castilla y León (Spain). Potted plants were grown in a scenario emulating the climate change environmental conditions expected by the end of this century, i.e., with elevated CO2 and high temperature under two water deficit regimes: long (LWD) and terminal (TWD). Changes in biomass and morphology, the content of proline (Pro), ascorbate (AsA) and glutathione (GSH), and enzymatic antioxidant activities were analyzed in flag leaves and ears. Additionally, leaf gas exchange was measured. LWD caused a decrease in biomass and AsA content but an increase in Pro content and catalase and GSH reductase activities in flag leaves, whereas TWD produced no significant changes. Photosynthesis was enhanced under both water deficit regimes. Increase in superoxide dismutase activity and Pro content was only observed in ears under TWD. The lack of a more acute effect of LWD and TWD on both organs was attributed to the ROS relieving effect of elevated CO2. Gazul acted as a drought tolerant variety with anisohydric behavior. A multifactorial analysis showed better adaptation of ears to water deficit than flag leaves, underlining the importance of this finding for breeding programs to improve grain yield under future climate change.
