Special Issue Information

Dear Colleagues,

Fresh fruits and vegetables are essential components of a healthy diet. However, a wide range of fruit and vegetable diseases negatively affects their quality and nutritional value. The causes of fruit and vegetable diseases mainly include 1) invasion by pathogenic microorganisms, such as fungi, bacteria, and viruses; 2) abiotic factors, such as climate change, sick soil syndrome, soil degradation, improper irrigation; and 3) weak resistance of many fruit and vegetable varieties. Various strategies have been proposed, including physical control (regulating temperature, light, air, heat, etc.), chemical control (using various chemical agents), and biological control (utilizing plant extracts, biological preparations, etc.). However, with the continuous increase in the human population and higher standards of living, the rise in intensive agricultural production systems, the extensive use of pesticides and chemical fertilizers, and the unrestrained utilization of soil have led to the development of resistance in plant pathogens to traditional treatment methods and a concomitant increase in soil-borne diseases. To meet the increasing demand for fruit and vegetable production and to meet quality requirements, it is necessary to conduct in-depth research on the mechanisms of fruit and vegetable diseases and develop more efficient and practical control methods.

This Special Issue welcomes original and review articles in (but not limited to) the following areas:

  • New emerging fruit and vegetable pathogens and their control;
  • New methods for detecting fruit and vegetable pathogens;
  • The mechanism of fruit and vegetable diseases reducing nutritional quality;
  • The mechanism of fruit and vegetable nutrition interacting with soil microorganisms;
  • New strategies and methods for eliminating fruit and vegetable viruses;
  • The mechanism and control methods of fruit and vegetable diseases caused by environmental stress;
  • Fruit and vegetable breeding and disease control.

Red raspberry fruit is highly perishable, and raspberry plants are sensitive to drought and low-temperature stress because of their shallow root system, which limits production and postharvest utilization in cold regions. In this study, RiACO1 was cloned from red raspberry (‘Polka’) and analyzed by bioinformatics, subcellular localization, tissue-specific expression, heterologous overexpression in Arabidopsis thaliana, and transient overexpression in white-stage raspberry fruit. The full-length RiACO1 coding sequence was 963 bp and encoded a 320-amino-acid protein that localized to the cytoplasm and nucleus. RiACO1-overexpressing Arabidopsis lines showed higher survival rates under drought and low-temperature stress, accompanied by increased proline content, chlorophyll retention, and antioxidant enzyme activities, as well as reduced Malondialdehyde (MDA) and Reactive Oxygen Species (ROS) accumulation. In raspberry fruit, transient RiACO1 overexpression increased RiACO1 transcript levels, ACO activity, and ethylene production and was associated with accelerated softening, anthocyanin accumulation, and chlorophyll degradation. These results indicate that RiACO1 is involved in ethylene-associated fruit ripening and may contribute to abiotic-stress responses; however, its direct breeding value in raspberry requires further validation through stable raspberry transformation or targeted loss-of-function approaches.

Under global climate change, cabbage (Brassica oleracea var. capitata), a major vegetable crop, is increasingly exposed to intermittent and fluctuating drought stress. A multi-level investigation of its adaptive strategies under water-deficit conditions is therefore essential for a comprehensive understanding of drought tolerance and for accelerating genetic breeding programs. In this study, the drought-resistant cultivar ‘ZG-628’ and the drought-sensitive cultivar ‘ZG-21’ were selected based on seed germination indices. Integrated physiological measurements, transcriptomic profiling, and metabolomic analyses were conducted to systematically compare their responses to drought stress. The results showed that the drought-resistant genotype ‘ZG-628’ maintained better water status, exhibited higher antioxidant enzyme activities, and accumulated greater levels of osmotic regulators under drought conditions. In addition, ‘ZG-628’ preserved higher chlorophyll content and photosynthetic efficiency than the sensitive genotype. At the molecular level, ‘ZG-628’ primarily responded to drought through key components of the abscisic acid (ABA) signaling pathway, including PYL, PP2C, and SnRK2. Metabolomic analysis further revealed preferential accumulation of flavonoids and ABA-related metabolites ‘ZG-628’, accompanied by specific activation of the “flavonoid and flavonol biosynthesis” pathway. Integrated multi-omics analysis indicated that plant hormone signal transduction was the most significantly enriched pathway among drought-responsive differentially expressed genes. Overall, this study systematically elucidates the coordinated multi-omics mechanisms underlying drought resistance in cabbage and provides both a theoretical basis and potential molecular targets for breeding drought-tolerant cabbage varieties.

Huanglongbing (HLB), primarily caused by ‘Candidatus Liberibacter asiaticus’ (CLas), threatens global citrus production. Deciphering the molecular interplay between citrus and CLas is crucial for successful control. This review synthesizes current understanding of the molecular mechanisms underlying citrus-CLas interactions, providing a comprehensive overview that spans immune signaling, hormonal and metabolic reprogramming, non-coding RNA-mediated regulation, pathogen effector biology, and emerging biotechnological interventions. We detail the hierarchical host response: initial immune recognition via pattern recognition receptors, triggering reactive oxygen species bursts and calcium signaling. Moreover, hormonal network reprogramming and their complex interplay in defense/susceptibility are examined. Transcriptomic studies have revealed key features of metabolic reprogramming, including suppression of photosynthesis and impairment of phloem function. Additionally, long-term strategies like cell wall reinforcement, accumulation of defensive compounds such as flavonoids and terpenoids, and roles of post-transcriptional regulation of microRNAs are discussed. Conversely, CLas counter-defense, notably effector-mediated immunity suppression and host metabolism manipulation, is also considered. Comparative transcriptomics between tolerant and susceptible varieties identifies tolerance or resistance genes/pathways for breeding and engineering. Despite this progress, critical knowledge gaps remain, particularly regarding the precise molecular mechanisms of CLas immune evasion and effector-mediated suppression, the genetic basis of natural tolerance, and the field-level efficacy of defense priming strategies. Future research directions should integrate single-cell omics, CRISPR/Cas9 editing, nano-enabled delivery, and microbiome engineering to bridge these gaps and accelerate HLB-tolerant/resistant citrus development. This review synthesizes how molecular profiling advances understanding of citrus defense mechanisms against HLB, and underscores the imperative for interdisciplinary research and global collaboration.
