Special Issue Information

Dear Colleagues,

The diseases and pests of vegetable and fruit crops generate a huge annual loss of production worldwide. Policy choices and the awareness of farmers and consumers in many parts of the world have led to significant changes in the use of chemicals in agricultural production. Thus, the number of pesticides used for the fight against fungal diseases and insects has been reduced considerably. It therefore appears necessary to research, test, and validate new solutions that will enable farmers to fight, regulate, and protect their crops against diseases and pests.

Plants have means of protection and/or ways to fight off microorganisms or insect attacks. Many of these means are secondary metabolites (essential oils, glucosinolates, alkaloids, etc.). In recent years, new strategies based on the use of these molecules have been proposed as natural means to protect crop production. By considering the expression “from the plant to products for the plant”, this Special Issue is open to all studies on molecules, resulting from primary and/or secondary metabolisms, to fight against diseases and pests of vegetables and fruit crops. This Issue aims to cover a wide array of research, ranging from the prospection of natural active molecules, and their actions against pests and diseases; modes of action; experiments in agricultural conditions (greenhouse, in the field, or during storage); and formulation tests and performances in agronomic situations; to the effect on the environment (life in the soil, crop auxiliaries, etc.), plants, and humans (health and residues in food).

This Special Issue is open to contributions on the following topics: 

- Active molecules (sources, compositions, productions, etc.)

- Secondary metabolites

- Lipids

- Vermicompost

- Biostimulants

- Effects on pests and crop diseases

- Effects on crops

- Contributions of adjuvants and formulations on the activity

- Economic studies of the use of these molecules

- Environmental impact (soil, plants, auxiliaries, persistence, etc.)

Fusarium wilt results in undesirable effects on the quality and production of chieh-qua (Benincasa hispida Cogn. var. Chieh-qua How). Fusaric acid (FA), a secondary metabolite of biotin produced by pathogens of genus Fusarium, induced resistant responses in chieh-qua; however, the physiological and molecular mechanism(s) of FA resistance remains largely unknown. In our study, ‘A39’ (FA-resistant cultivar) exhibited decreased malondialdehyde (MDA) content and increased superoxide dismutase (SOD) enzyme activity when exposed to FA compared with ‘H5’ (FA-susceptible cultivar). More apoptosis cells existed in ‘H5’ than ‘A39’ after 2 days of FA treatment. RNA-seq results revealed that a total of 2968 and 3931 differentially expressed genes (DEGs) were detected under normal conditions (1562 up-regulated and 1406 down-regulated) and FA treatment (2243 up-regulated and 1688 down-regulated), respectively. Interestingly, DEGs associated with pathogen-related protein and ethylene (ET) biosynthesis and signal pathways were most significantly changed during FA stress. Notably, several crucial genes encoding pathogenesis-related protein (CL4451.Contig2, CL2175.Contig4), peroxidase (Unigene49615 and CL11695.Contig2), and ET-responsive transcription factors (TFs) (CL9320.Contig1, CL9849.Contig3, CL6826.Contig2, CL919. Contig6, and CL518.Contig7) were specifically induced after FA treatment. Collectively, the study provides molecular data for isolating candidate genes involved in FA resistance, especially ET related genes in chieh-qua. Full article
