Special Issue Information

Dear Colleagues,

Plants growing under field conditions are constantly exposed, either sequentially or simultaneously, to more than one abiotic or biotic stress factors. Plants have developed unique strategies to respond to ever-changing environmental conditions, which enable them to perceive changes in their surroundings and adjust their metabolic systems to maintain homeostasis accordingly. Recently, priming-mediated stress and cross-stress tolerance (i.e., greater tolerance to a second stronger stress after exposure to a different or similar mild primary stress) have attracted considerable interest from the scientific community as a potential means of stress management and also for producing stress-resilient crops in order to aid with sustaining global food security. Since then, many studies dealing with a range of crop species under different conditions have focused on priming-mediated stress and cross-stress tolerance in crop plants, and recent results have indicated that plants have a “memory” process where a past stress exposure enables them to be better prepared for exposure to stress in the future. Because it is known that the induction of cross-tolerance in crop plants often involves common factors, an in-depth understanding of the biochemical and molecular mechanisms associated with the development of cross-stress tolerance in plants is still lacking. Hence, there is an urgent need to improve our understanding of the complex mechanisms involved in priming-mediated stress and cross-stress tolerance in order to help develop modern varieties of crop plants that are more resilient to environmental stress. We invite original and review articles on the latest understanding of the physiological, biochemical, and molecular basis of priming-mediated stress tolerance and cross-stress tolerance in crop plants. This would help researchers to devise strategies for enhancing crop productivity under stressful conditions. It would have further importance for improved utilization of natural resources in advanced plant breeding and genetic engineering, contributing to future food security.

Topics appropriate to this Special Issue include, but are not limited to, the following:

  • Salt priming and abiotic stress tolerance in crop plants
  • Cold priming and abiotic stress tolerance in crop plants
  • Heat priming and abiotic stress tolerance in crop plants
  • Reactive oxygen species (ROS) priming and abiotic stress tolerance in crop plants
  • Chemical priming and abiotic stress tolerance in crop plants
  • Comparative effectiveness of chemical priming in abiotic stress tolerance in crop plants
  • ROS metabolism, endogenous protective chemicals, and abiotic stress tolerance in crop plants
  • Proteomic analysis, chemical priming, and abiotic stress tolerance in crop plants
  • Chemical priming and stress responsive gene expression
  • Breeding for endogenous chemical compounds and abiotic stress tolerance in crop plants
  • Signaling roles of chemical compounds and cross stress tolerance in crop plants

The brown planthopper, Nilaparvata lugens (Stål)[BPH], is a damaging pest of rice in Asia. Insecticides and rice varietal resistance are widely implemented BPH management practices. However, outbreaks of BPH have been linked to excessive insecticide use—challenging the compatibility of these two management practices. IR62 is a variety with resistance against BPH, the whitebacked planthopper, Sogatella furcifera Horváth [WBPH], and the green leafhopper, Nephotettix virescens (Distant)[GLH]. We compared BPH responses to IR62 and to the susceptible variety IR64 treated with buprofezin, carbofuran, cartap hydrochloride, cypermethrin, deltamethrin, fipronil, or thiamethoxam + chlorantraniliprole. In greenhouse bioassays, cypermethrin, fipronil and thiamethoxam + chlorantraniliprole reduced egg laying on both varieties, and, together with buprofezin, reduced nymph survival to zero. Buprofezin, carbofuran, and cartap hydrochloride stimulated egg laying, and carbofuran increased nymph biomass, but these effects were reduced on IR62. Planthopper populations were ten times higher on deltamethrin-treated rice than untreated rice in a screenhouse experiment. Host resistance failed to buffer against this insecticide-induced resurgence in BPH and WBPH. However, IR62 reduced the effect in GLH. Rice treated with cypermethrin and fipronil had reduced yields compared to untreated controls, suggesting possible phytotoxic effects. We found little evidence of synergies between the two management practices; but host resistance did buffer against the undesirable effects of some insecticides. Full article

Seedling vigor and regrowth ability are important traits for the forage production of winter wheat. The objectives of this study were to map quantitative trait loci (QTL) associated with seedling vigor and regrowth vigor traits using a genome-wide association mapping study (GWAS). Seedling vigor and regrowth vigor were evaluated with shoot length, the number of shoots per plant and shoot dry weight per plant 45 days after planting and 15 days after cutting. A large phenotypic variation was observed for all the traits studied. In total, 12 significant QTL for seedling vigor and 16 for regrowth vigor traits were detected on various chromosomes. Four QTL on chromosomes 2B, 4B, 5A and 7A for seedling vigor co-localized with QTL for regrowth vigor due to significant correlations between corresponding traits of the initial growth and regrowth. A BLAST search using DNA sequences of the significant loci revealed candidate genes playing roles in vegetative and reproductive development in different crop species. The QTL and single-nucleotide polymorphism (SNP) markers identified in this study will be further validated and used for marker-assisted selection of the traits during forage wheat breeding.

Treating plants with elevated carbon dioxide (eCO2) can increase their drought tolerance. Increased atmospheric CO2, a fundamental factor in climate change, may compensate for the drought-induced reduction in crop growth and yield. Basil, being moderately sensitive to drought stress (DS), experiences several morphological changes under DS. Thus, we designed an experiment that addresses how DS and different levels of CO2 affect the overall morphological growth patterns during basil’s early and late-season growth. The experiment was conducted under four different growth conditions: two water treatments, (1) a full-strength Hoagland’s solution was added to the basil plants at 120% of the evapotranspiration each day, and (2) 50% of the full-strength Hoagland’s solution was added to basil plants for the drought treatment, alongside two levels of CO2 application [ambient 420 ppm (aCO2) and elevated 720 ppm (eCO2)]). The DS had a severe impact on the morphological traits of the shoot and root systems. Compared to control, DS reduced the marketable fresh mass (FM) by 31.6% and 55.2% in the early and late stages of growth. FM was highest under control + eCO2 (94.4–613.7 g) and lowest under DS + aCO2 (67.9–275.5 g). Plant height under DS + aCO2 and DS + eCO2 reduced by 16.8% and 10.6% during the late season. On the other hand, dry mass percent (DM%) increased by 31.6% and 55.2% under DS + eCO2 compared to control in the early and late stages of growth, respectively. This study suggested that eCO2 during DS significantly impacts basil morphological traits compared to aCO2. Besides, anthocyanin decreased by 10% in DS + aCO2 and increased by 12.6% in DS + aCO2 compared to control. Similarly, nitrogen balance index, a ratio of chlorophyll and flavonoids, was recorded to be the highest in DS + aCO2 (40.8) compared to any other treatments. Overall, this study indicates that the suppression of basil’s morphophysiological traits by DS is more prominent in its later growth stage than in the earlier stages, and eCO2 played an important role in alleviating the negative effect of DS by increasing the DM% by 55%.
