Special Issue Information

Dear Colleagues,

Abiotic stresses like drought, salinity, extreme temperatures, and nutrient deficiencies significantly affect the growth, development, and yield of vegetable crops. These stresses impact plant physiology and interact with soil microorganisms, influencing crop resilience. Understanding the genetic mechanisms behind these interactions is essential for enhancing stress tolerance and improving agricultural sustainability.

Current research focuses on how genetic factors and soil microbes interact to regulate stress tolerance. Key areas of interest include plant responses to stress signals, the role of genes in signaling pathways, osmotic regulation, and antioxidant defense. Soil microorganisms, such as beneficial bacteria and fungi, also alleviate stress by promoting nutrient uptake, modulating stress hormones, and enhancing plant resistance.

This Special Issue invites contributions on several topics, as follows: the molecular mechanisms of abiotic stress perception, the role of soil microorganisms in stress tolerance, the identification of novel genes for stress resilience, microbial-driven mitigation strategies, biotechnological approaches like CRISPR/Cas9 for stress resistance, and the ecological impacts of plant–microbe interactions under stress conditions.

The goal of this Special Issue is to deepen our understanding of the genetic and microbial interactions that help vegetable crops withstand abiotic stresses, aiming to improve crop resilience, productivity, and sustainability in challenging environments.

Excessive use of fertilizers will not only cause the enrichment of soil N nutrients, soil secondary salinization, soil acidification, and an imbalance of the soil microbial community structure, but will also lead to the nitrate content of vegetables and the ground water exceeding the standard. The application of bio-organic fertilizer could reduce the amount of mineral fertilizer used. However, the effects of nitrogen reduced with different bio-organic fertilizers on soil chemical properties, microbial community structure, and the yield and quality of radish are not clear. In a field experiment, we designed six fertilization treatments: no fertilization (CK), conventional fertilization (T1), a total nitrogen reduction of 20% (T2), and a total nitrogen reduction of 20% with “No. 1”, “Seek” or “Jiajiapei” bio-organic fertilizers. The results showed that nitrogen reduction of 20% with Bacillus bio-organic fertilizer (N1) significantly increased the organic matter, pH, total nitrogen content, and the relative abundance of Bacillus and Streptomyce in the soil compared with T1. RDA analysis showed that the pH, organic matter content, invertase and fluorescein diacetate enzyme activity of the soil were significantly correlated with the soil microbial community structure. In addition, the yield and Vc content in radish were increased with the application of bio-organic fertilizers, while on the contrary, the nitrate and cellulose content were decreased, and the N1 treatment showed the best effect. Moreover, the yield had a significant positive correlation with Bacillus. Overall, nitrogen reduction with bio-organic fertilizers, especially full-effective “No. 1” enriched with Bacillus, could alter the soil microbial community structure and effectively improve soil fertility, which in turn enhanced the yield and quality of radish. An application of Bacillus bio-organic fertilizer was an effective strategy to improve soil quality and vegetable safety. Full article
