Special Issue Information

Dear Colleagues,

Grapevine (Vitis vinifera L.) is one of the main crops worldwide. It has been cultivated since ancient times and its susceptibility to many different pests and diseases is well known. Potential disease-producing agents are many and very diverse, including viruses, fungi, nematodes, bacteria, and phytoplasmas.

Reducing the damage caused by these biotic agents is a priority to maintain the productivity and profitability of this crop. Traditionally, integrated control methods (IPM) have been used, by combining the effects of chemical treatments, cultural management techniques, tolerant cultivars, and biological control. Although much research has been conducted on grapevine diseases in the past, the arrival of new knowledge, new methods, and new techniques (higher resolution molecular techniques, massive genome sequencing, image analysis, sensors, risk assessment models, etc.) opens the door to innovative control strategies.

Research articles, review articles, as well as short communications are invited. The aim of this Special Issue is to share new knowledge and scientific-based methods focused on any aspect related to the understanding and optimization of grapevine disease control.

Induced resistance (IR) based on elicitors application aims to strengthen plant defenses, rather than directly targeting pathogens. These compounds are less toxic than conventional pesticides and are useful in reducing their use. Strategies based on COS–OGA, Swinglea glutinosa, and low copper doses were tested in this three-year (2021–2023) field investigation against grapevine downy (DM) and powdery (PM) mildew. Their effectiveness was compared to copper, sulfur, untreated, and water-sprayed plants in a naturally infected vineyard. Combined treatments provided higher levels of protection. COS–OGA at 2 L ha−1 combined with low copper doses and an adjuvant protected canopy and production from both DM and PM at the same level as copper and farm application (based on copper and sulfur). In favorable seasons, 2023 for DM and 2022 for PM, this strategy reduced the DM McKinney Index compared to untreated plants by 74% and 39% on leaves and bunches, respectively. Reductions observed for PM were 85% on leaves and 46% on bunches. S. glutinosa showed reductions only in one assessment against PM on bunches. This work validates IR-based DM and PM management strategies under field conditions and paves the way toward concrete reduction in copper and sulfur use in vineyards. Full article

Grapevine (Vitis vinifera L.) varieties are particularly susceptible to the pathogens downy mildew Plasmopara viticola and powdery mildew Erysiphe necator. Conventional methods for identifying and classifying spores rely on time-consuming microscopic examinations susceptible to human error and requiring qualified personnel. The aim of the present work has focused on the establishment of a protocol for the rapid molecular detection of the fungal species P. viticola and E. necator from adhesive tapes used to trap spores in airborne inoculum collector cyclones. Four DNA extraction methods were tested. Subsequently, molecular detection of both pathogens was performed by validating some of the specific molecular markers available in the literature. PCR with the primers Nad9 cob-F/Nad9 cob-R and Uncin144/Uncin511 showed specific results for P. viticola and E. necator, respectively, and the best results were obtained with the T-CTAB method. The methodology developed in this work could be of great help for relating direct measurement of P. viticola and E. necator airborne inoculum to disease risk and detection of pathogens, which could be integrated into the early diagnosis of these grapevine pathogens, improving existing warning systems such as Decision Support Systems.

This article emphasizes the crucial importance of yeast Meyerozyma guilliermondii (Patent CECT13190) as a biological control agent (BCA) in eliciting defensive responses in vine plants, and is supported by comprehensive physiological, proteomic, and transcriptomic analyses. The results demonstrate that the BCA M. guilliermondii can induce enhanced defensive responses, as reflected in the regulation of key proteins. Notably, the upregulated expression of calmodulin and pathogenesis-related protein 10 (PR-10) are indicative of a complex interplay between calcium signalling, salicylic acid accumulation, and the elicitation of plant defence responses against pathogens. Furthermore, changes in microtubule dynamics and proteins related to protein synthesis and folding are observed, confirming the elicitation of defence responses. The correspondence between proteomic and transcriptomic analyses for genes codifying pathogenesis-related proteins, such as Vcgns1, VviTL1, and Vcchit1b, reinforces the empirical robustness of our findings. Collectively, our research explores the modulation of plant defences by the BCA, opening promising avenues for innovative agricultural strategies that enhance crop resilience and productivity.

To obtain effective biocontrol strains for downy mildew of grape, 38 endophytic bacteria were isolated from fruits, seeds, and old stems of six grape varieties. Using spot inoculation mixtures of sporangial suspensions of Plasmopara viticola and biocontrol bacterial suspension, this screen yielded three strains (G1, G5, and G9) with good antagonistic effects against P. viticola. The growth inhibition rate was 100%, which was comparable to the effect of the positive control Bacillus subtilis strain CN181. The enzyme activity and the metabolites of strain G1 were examined on casein hydrolysate medium, sodium carboxymethyl cellulose agar plates, and chrome azurol sulfonate (CAS) agar plates. The antifungal protein component was identified by liquid chromatography–mass spectrometry (LC–MS). The results showed that strain G1 was more effective against Plasmopara viticola after two field trials, and the inhibition rates of strain G1 on the seventh day of the two field trials were 47.5% and 36.9%, respectively. Strain G1 was identified as Bacillus amyloliquefaciens based on morphological examination and 16S rDNA sequence analysis. It produced proteases, cellulases, and siderophores. Crude protein of the strain mainly included the putative segregation protein SpoVG, which inhibited P. viticola. Full article
