Special Issue Information

Dear Colleagues,

Some of the main challenges of present and future agriculture are the deterioration of the environmental conditions in many areas of the world and the uncertainty of climate. Therefore, improving crop tolerance to different types of abiotic stress is a priority to ensure a stable food supply for a growing human population. The nature of different abiotic stresses is very diverse, and so are plants' responses to them.

This Special Issue will focus on the "Physiological and Molecular Characterization of Crop Resistance to Abiotic Stress". We invite novel research articles, reviews, and opinion papers covering all aspects of plant responses and mechanisms of tolerance to abiotic stresses such as salinity, drought, extreme temperatures, flooding, nutrient deficiencies, high radiation levels, toxic compounds (heavy metals, pesticides), ozone, etc. Physiological, biochemical, and molecular studies of crop responses to abiotic stresses, as well as papers describing the function of stress-responding genes, the development of stress-tolerant varieties, marker-assisted screening of stress-tolerant genotypes, and genetic engineering and other biotechnological approaches to improve crop tolerance will be welcomed.

For improving lodging resistance and increasing grain yield in wheat in the Yellow-Huai River Basin in China, different sowing modes have been investigated. Conventionally, the small-flat-plot sowing mode has been adopted in wheat cultivation. However, this sowing mode leads to heavy lodging and low land use efficiency. In this study, a new sowing mode, high-low-plot sowing mode with two more rows sowed on the high plot, was investigated. Two cultivars, Hengguan 35 and Jimai 44 were used for two seasonal field experiments from 2018 to 2020. The results showed that grain yield improved with the high-low sowing mode by as much as 25% since more spikes per unit area were observed concomitant with reduced stem lodging. The grain yield increase was mainly due to the enhanced spike number per m2, while the lodging resistance was improved through the lowered plant height and the center of gravity height. This research proves that the high-low-plot sowing mode is an improved sowing mode for producing greater grain yield with better lodging resistance in the wheat production area in northern China.

Soil salinity and the indiscriminate use of agrochemicals has significantly reduced the productivity of the ‘Chinampas’ agroecosystem in Mexico City. Crop improvement under these stressful conditions may be achieved by soil bioremediation. In this study, we checked the effects of the organochlorine pesticide endosulfan and bioremediation with Penicillium crustosum or a citric waste on the growth of Phaseolus leptostachyus plants in saline soil from the Chinampas area. Biochemical markers associated with specific stress responses were also determined after one month of growth in the different substrates. Plant growth was stimulated by bioremediation of the soil. Both biostimulants reduced the degree of stress affecting the plants, as shown by the increase in photosynthetic pigments and the reduction of proline, malondialdehyde (MDA), and H2O2 contents, and the activation of antioxidant systems. However, the biostimulants appeared to mitigate oxidative stress through different mechanisms. Endosulfan contamination inhibited seed germination—which was reverted to control values in the presence of the biostimulants—and further decreased plant growth. No clear patterns of variation of biochemical stress markers were observed combining endosulfan and the biostimulants. In any case, bioremediation with P. crustosum and/or citric waste is recommended to improve the germination and growth of P. leptostachyus plants. Full article

Sugarcane (Saccharum spp.) is one of the most important industrial cash crops, contributing to the world sugar industry and biofuel production. It has been cultivated and improved from prehistoric times through natural selection and conventional breeding and, more recently, using the modern tools of genetic engineering and biotechnology. However, the heterogenicity, complex poly-aneuploid genome and susceptibility of sugarcane to different biotic and abiotic stresses represent impediments that require us to pay greater attention to the improvement of the sugarcane crop. Compared to traditional breeding, recent advances in breeding technologies (molecular marker-assisted breeding, sugarcane transformation, genome-editing and multiple omics technologies) can potentially improve sugarcane, especially against environmental stressors. This article will focus on efficient modern breeding technologies, which provide crucial clues for the engineering of sugarcane cultivars resistant to environmental stresses. Full article
