Gray blight of tea, caused by several Pestalotiopsis-like species, is one the most destructive foliar diseases in tea cultivation yet characteristics these pathogens have not been confirmed until now. With morphological and multigene phylogenetic analyses, we identified gray fungi as Pseudopestalotiopsis camelliae-sinensis, Neopestalotiopsis clavispora, Pestalotiopsis camelliae. Phylogenetic analyses derived from combined internal transcribed spacer, β-tubulin, translation elongation factor...
Leaf spots are the most damaging and common foliar diseases of tea caused by several species fungi. During 2018 to 2020, leaf spot showing different symptoms (large small spots) were observed in commercial plantations Guizhou Sichuan provinces China. The pathogen causing two sized was identified as same (Didymella segeticola) based on morphological characteristics, pathogenicity, multilocus phylogenetic analysis using combined ITS, TUB, LSU, RPB2 gene regions. Microbial diversity lesion...
Brown blight disease caused by Colletotrichum species is a common and serious foliar of tea (Camellia sinensis). Fungal isolates from several plantations causing typical brown symptoms were identified as belonging to the acutatum complex gloeosporioides based on morphological characteristics well DNA analysis internal transcribed spacer (ITS) glyceraldehyde 3-phosphate dehydrogenase (GAPDH). acutatum, new causal agent associated with C. sinensis, showed high phenotypic genotypic diversity...
In tea (Camellia sinensis) plants, polyphenols are the representative metabolites and play important roles during their growth. Among polyphenols, catechins extensively studied, while very little attention has been paid to other such as gallic acid (GA) that occur in leaves with relatively high content. this study, GA was able be transformed into methyl gallate (MG), suggesting is not only a precursor of catechins, but also can plants. content higher than MG content—regardless cultivar,...
Ganpu is an unique tea product made by Pu-erh and citrus peel. In this study, the non-volatiles changes of during processing were fully analyzed UPLC-ESI-MS/MS. Total 276 significantly differential metabolites in detected (P < 0.05, VIP > 1), their change trend clustered into 8 subclasses K-means analysis. Metabolites present at various processes revealed. 72 1 fold ≥2 or ≤0.5) between any two stages identified fixation was key step with 61 metabolites. 39 flavonoids 2 lignans coumarins...
Blister blight, as one of the most threatening and damaging disease worldwide, mainly infects young organs tissues seriously affecting tea growth quality. In this study, spread pathogen on leaves were examined by toluidine blue staining, scanning electron microscope transmission analysis. The composition abundance fungal community leaf firstly analyzed. Sensory evaluation metabolites analysis indicated that diseased had strong sweet taste soluble sugars contributed significantly to taste,...
Blister blight and small leaf spots are important alpine diseases that mainly attack tender tea leaves, affecting quality. However, there is limited information on the effect of these tea’s non-volatile volatile metabolites. Metabolomic analysis based UHPLC-Q-TOF/MS, HPLC GC/MS was used to reveal characteristic chemical profiles leaves infected with blister (BB) (SS). Flavonoids monolignols were metabolites enriched significantly changed. Six main involved in phenylpropanoid biosynthesis...
Gray blight, caused by Pestalotiopsis-like species, is one of the most serious diseases in tea [Camellia sinensis (L.) O. Kuntze] production. In this study, eight Pestalotiopsis isolates obtained from diseased leaves collected Chongqing, China were identified as P. chamaeropis Maharachch, K.D. Hyde & Crous. a causal agent gray blight disease was clearly distinguished other species genus morphological characteristics and phylogenetic analysis based on combination internal transcribed spacer...
Brown blight, as the most damaging and common foliar disease of tea plant (Camellia sinensis) in China, has been recently reported to be caused by different species genus Colletotrichum. During years 2016 2017, plants commercial cultivation areas Chongqing City that significant incidences brown blight were investigated then analyzed using both morphological characteristics multilocus phylogenetic analysis. The results showed at least five Colletotrichum identified, including four well-known...
Albino tea has attracted increased attention due to its unique flavour. To reveal the difference in key metabolites constituting important quality of different resources, amino acids and flavonoids profiles three albino resources with degrees albinism one green variety were comprehensively investigated. K-means analysis revealed 35 significantly enriched ‘Jibai’ (JBH), while 3 2 specifically accumulated ‘Huangjinya’ (HJY) ‘Anjibaicha’ (AJB), respectively. Based on OPLS-DA models, 40, 31 45...
