Cucurbitaceae, the gourd family of flowering plants, is a very large and diverse family, order Cucurbitales, contains 95 genera 950–980 species food ornamental wild weedy mostly with high genetic diversity. This review focused on most important cucurbit crops (Cucumis sativus, Cucumis melo, Cucurbita spp., Citrullus lanatus, Momordica charantia, Lagenaria siceraria, Luffa acutangula) some their relatives as hosts powdery mildews (CPM). Powdery (PM) (Ascomycota, Erysiphales) are one frequently encountered easily visible groups plant pathogenic fungi > 900 species. They obligate biotrophs, they colonize above-ground tissues, leaves, though may also stems, petioles, flowers fruits, usually debilitators, not killers. These parasitic have been problematic cucurbits for long time world-wide, causing serious economic losses in yield quality. All economically host CPM.

Wheat Chromatin Remodeling Protein TaSWP73 Contributes to Compatible Wheat–Powdery Mildew Interaction

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(6), С. 2590 - 2590

Опубликована: Март 13, 2025

Wheat powdery mildew disease caused by the obligate biotrophic fungal pathogen Blumeria graminis forma specialis tritici (B.g. tritici) seriously threatens global wheat production. Although improved resistance is an aim in breeding, regulatory mechanism underlying wheat–B.g. interaction remains poorly understood. In this study, chromatin remodeling protein TaSWP73 was identified as a negative regulator of post-penetration against B.g. tritici. The transient overexpression attenuates tritici, while silencing potentiates salicylic acid (SA) biosynthesis and activates Importantly, promoter regions TaSARD1, activator gene SA biosynthesis, marked high nucleosome occupancy TaSWP73-silenced leaves. TaSARD1 could suppress attenuate with lack TaSWP73. addition, TaICS1 characterized essential component biosynthetic machinery. Potentiated increased be suppressed expression. These results collectively support hypothesis that contributes to compatible wheat–powdery presumably via suppression TaSARD1-TaICS1-SA pathway.

Genetic Dissection of the Powdery Mildew Resistance in a Cultivated Emmer Wheat Accession

Agronomy, Год журнала: 2025, Номер 15(4), С. 980 - 980

Опубликована: Апрель 18, 2025

Blumeria graminis f. sp. tritici (Bgt), the causal agent of wheat powdery mildew, poses a significant threat to global production. In this study, we identified and characterized broad-spectrum mildew resistance gene, PmL709, in resistant cultivated emmer (Triticum dicoccum) accession: L709. Using bulked segregant RNA sequencing (BSR-Seq) analysis molecular markers, PmL709 was mapped 1.7 cM interval on chromosome arm 2BS, flanked by markers Xdw05/YTU95-04/YTU95-06/YTU95-08/Xdw10/Xdw11 YTU692B-094, corresponding 21.82–25.94 Mb physical (cv. Svevo), using segregated population crossed L709 susceptible durum cultivar, Langdon. Referring origin, spectra, position with known genes likely be an allele Pm68. Transcriptomic revealed 3923 differentially expressed (DEGs) between bulks, enriched pathways such as phenylpropanoid biosynthesis, MAPK signaling, plant–pathogen interactions. qRT-PCR validated differential expression nine candidate within interval, highlighting their potential roles disease resistance. The flanking could accurately trace presence from accession survey 46 accessions. These findings provide valuable insights into genetic mechanisms offer practical tools for marker-assisted breeding develop cultivars.

The yield and quality of cultivated food crops are frequently compromised by the prevalent threat from fungal pathogens that can cause widespread damage in both pre-harvest post-harvest stages. This paper investigates challenges posed to sustainability essential crops, leading significant economic security repercussions. critiques long-standing reliance on synthetic fungicides, emphasizing environmental health concerns arising their occasionally inappropriate use. In response, explores potential biological control agents, specifically endophytic fungi advancing sustainable agricultural practices. Through diverse symbiotic relationships with host plants, these exhibit strong antagonistic capabilities against phytopathogenic producing various bioactive compounds promoting plant growth. review elaborates direct indirect mechanisms antagonism, such as antibiosis, mycoparasitism, induction resistance, competition for resources, which collectively contribute inhibiting pathogenic consolidates crucial role fungi, i.e.,

Wheat Susceptibility Genes TaCAMTA2 and TaCAMTA3 Negatively Regulate Post-Penetration Resistance against Blumeria graminis forma specialis tritici

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(12), С. 10224 - 10224

Опубликована: Июнь 16, 2023

Blumeria graminis forma specialis tritici (B.g. tritici) is the airborne fungal pathogen that causes powdery mildew disease on hexaploid bread wheat. Calmodulin-binding transcription activators (CAMTAs) regulate plant responses to environments, but their potential functions in regulation of wheat-B.g. interaction remain unknown. In this study, wheat CAMTA factors TaCAMTA2 and TaCAMTA3 were identified as suppressors post-penetration resistance against mildew. Transient overexpression enhanced susceptibility B.g. tritici, while knockdown expression using transient- or virus-induced gene silencing compromised tritici. addition, TaSARD1 TaEDS1 characterized positive regulators Overexpressing confers enhances Importantly, we showed expressions potentiated by TaCAMTA3. Collectively, these results implicated Susceptibility genes contribute compatibility might via negative expression.
