Histological and transcriptomic insights into the interaction between grapevine and .

Introduction: Grape is of high economic value. , a pathogen causing grape ripe rot and leaf spot, threatens grape production and quality.

Methods: This study investigates the interplay between by Cytological study and transcriptome sequencing.

Comprehensive assessment of drought resistance and recovery in kiwifruit genotypes using multivariate analysis.

As global climate change persists, ongoing warming exposes plants, including kiwifruit, to repeated cycles of drought stress and rewatering, necessitating the identification of drought-resistant genotypes for breeding purposes. To better understand the physiological mechanisms underlying drought resistance and recovery in kiwifruit, moderate (40-45% field capacity) and severe (25-30% field capacity) drought stresses were applied, followed by rewatering (80-85% field capacity) to eight kiwifruit rootstocks in this study. We then conducted a multivariate analysis of 20 indices for the assessment of drought resistance and recovery capabilities.

An RxLR effector from Plasmopara viticola suppresses plant immunity in grapevine by targeting and stabilizing VpBPA1.

Grapevine downy mildew, caused by Plasmopara viticola, is one of the most devastating diseases in viticulture. Plasmopara viticola secretes RxLR effectors to modulate immune responses in grapevine. Here, we report an RxLR effector RxLR50253 from P.

VvHDZ28 positively regulate salicylic acid biosynthesis during seed abortion in Thompson Seedless.

Seedlessness in grapes is one of the features most appreciated by consumers. However, the mechanisms underlying seedlessness in grapes remain obscure. Here, we observe small globular embryos and globular embryos in Pinot Noir and Thompson Seedless from 20 to 30 days after flowering (DAF).

Insight Into Function and Subcellular Localization of Putative RxLR Effectors.

Grapevine downy mildew, caused by oomycete fungus , is one of the most devastating diseases of grapes across the major production regions of the world. Although many putative effector molecules have been identified from this pathogen, the functions of the majority of these are still unknown. In this study, we analyzed the potential function of 26 effectors from the highly virulent strain YL.

The Nuclear-Localized RxLR Effector PvAvh74 From Induces Cell Death and Immunity Responses in .

Downy mildew is one of the most serious diseases of grapevine ( spp). The causal agent of grapevine downy mildew, , is an obligate biotrophic oomycete. Although oomycete pathogens such as are known to secrete RxLR effectors to manipulate host immunity, there have been few studies of the associated mechanisms by which these may act.

Transcriptomic analysis of Chinese wild Vitis pseudoreticulata in response to Plasmopara viticola.

Downy mildew, resulted from Plasmopara viticola, is one of most severe fungal diseases of grapevine. Since Vitis vinifera is susceptible to downy mildew, much effort has been focused on improving the resistance of V. vinifera.

Grapevine VpPR10.1 functions in resistance to Plasmopara viticola through triggering a cell death-like defence response by interacting with VpVDAC3.

As one of the most serious diseases in grape, downy mildew caused by Plasmopara viticola is a worldwide grape disease. Much effort has been focused on improving susceptible grapevine resistance, and wild resistant grapevine species are important for germplasm improvement of commercial cultivars. Using yeast two-hybrid screen followed by a series of immunoprecipitation experiments, we identified voltage-dependent anion channel 3 (VDAC3) protein from Vitis piasezkii 'Liuba-8' as an interacting partner of VpPR10.
