“…Li screened transcription factors related to grapevine downy mildew, including ERF, MYB, WRKY and bHLH. MYB44, isolated from grapes, was significantly induced in response to the defense expressed in grapes after S. cinerea infection, interacting with the salicylic acid-responsive transcriptional coagulant NPR1 for defense expression [104]. In this study, the expression levels of transcription factor genes of the MYB family were also different among different samples, but the expression levels of the high-resistance group were significantly higher than those of the immune group.…”

Intraspecific recurrent selection in V. vinifera is an effective method for grape breeding with high quality and disease resistance. The core theory of this method is the substitution accumulation of multi-genes with low disease resistance. The discovery of multi-genes for disease resistance in V. vinifera may provide a molecular basis for breeding for disease resistance in V. vinifera. In this study, resistance to downy mildew was identified, and genetic analysis was carried out in the interspecific crossing population of V. vinifera (Ecolly × Dunkelfelder) to screen immune, highly resistant and disease-resistant plant samples; transcriptome sequencing and differential expression analysis were performed using high-throughput sequencing. The results showed that there were 547 differential genes (194 up-regulated and 352 down-regulated) between the immune group and the highly resistant group, and 103 differential genes (54 up-regulated and 49 down-regulated) between the highly resistant group and the highly resistant group, there were 199 differential genes (50 up-regulated and 149 down-regulated) between the two groups. KEGG analysis of differentially expressed genes in the immune versus high-resistance group. The pathway is mainly concentrated in phenylpropanoid biosynthesis, starch and sucrose metabolism, MAPK signaling pathway–plant, carotenoid biosynthesis and isoquinoline alkaloid biosynthesis. The differential gene functions of immune and middle-resistant, high-and middle-resistant combinations were mainly enriched in plant–pathogen interaction pathway. Through the analysis of disease resistance-related genes in each pathway, the potential minor resistance genes in V. vinifera were mined, and the accumulation of minor resistance genes was analyzed from the molecular level.

Banana Fusarium wilt caused by Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4) is one of the most destructive banana diseases in the world, which limits the development of the banana industry. Compared with traditional physical and chemical practices, biological control becomes a promising safe and efficient strategy. In this study, strain Y1-14 with strong antagonistic activity against Foc TR4 was isolated from the rhizosphere soil of a banana plantation, where no disease symptom was detected for more than ten years. The strain was identified as Streptomyces according to the morphological, physiological, and biochemical characteristics and the phylogenetic tree of 16S rRNA. Streptomyces sp. Y1-14 also showed a broad-spectrum antifungal activity against the selected 12 plant pathogenic fungi. Its extracts inhibited the growth and spore germination of Foc TR4 by destroying the integrity of the cell membrane and the ultrastructure of mycelia. Twenty-three compounds were identified by gas chromatography–mass spectrometry (GC-MS). The antifungal mechanism was investigated further by metabolomic analysis. Strain Y1-14 extracts significantly affect the carbohydrate metabolism pathway of Foc TR4 by disrupting energy metabolism.

Banana Fusarium wilt, which is known as Panama disease and caused by Fusarium oxysporum f. sp. cubense (Foc), is a destructive disease that can lead to plant death and complete loss of banana plantations. For obtaining resistant varieties against Fusarium wilt, research is required to elucidate the mechanisms of genetic resistance to Foc. In this research, the banana plants infected with banana bunchy top virus (BBTV) showed resistance to Foc. RNA-seq results showed that the infection with Foc upregulated many resistance-related genes in BBTV-positive plants, especially genes related to ROS production. It was also found that more H2O2 in BBTV-positive plants was induced during Foc infection. The movement protein (MP) of BBTV could increase H2O2 levels by promoting the accumulation of MaSGT1a (suppressor of the G-two allele of SKP1) via direct interaction. Thus, the resistance to Foc induced by BBTV may attribute to MP increasing MaSGT1a protein levels to induce ROS production. MaSGT1a could promote the accumulation of R proteins MaRPM1 and MaRPP8, and increase H2O2 levels in Nicotiana benthamiana. The expression of R proteins in Nicotiana benthamiana caused an increase in H2O2 levels and promoted resistance to Foc. Thus, the MP of BBTV could induce plant defense through interaction with MaSGT1a. We speculate that MaSGT1a is likely involved in R gene-mediated resistance and thereby promotes the resistance of banana against Foc.
