Litchi ( chinensis ) pepper spot disease results in black spotting symptoms on litchi fruits. This was first observed cultivar Guiwei, Guangzhou, China, 2009, and then found widespread other litchi‐growing regions of China. Colletotrichum isolates were consistently recovered from typical lesions diseased fruits with frequency ranging 83% to 100%. Three representative Maoming, Guangzhou Shenzhen selected for identification pathogenicity testing the field. Based morphology phylogenetic...
Mango anthracnose is among the most severe diseases impacting mango yields and quality. While this disease can be effectively controlled through chemical means, it vital that appropriate field efficacy fate determination studies conducted when applying pesticides to crops in order appropriately gauge ecological health risks associated with use of these agents.GAP trials were explore efficacy, dissipation, terminal residues application mefentrifluconazole pyraclostrobin six locations...
Bacteria, inhabiting around and in plant roots, confer many beneficial traits to promote growth health. The secretion of root exudates modulates the nutritional state rhizosphere area, further selecting specific bacteria taxa shaping communities. Many studies effects have demonstrated that selection by consistently enriches a set taxa, this is conserved across different species. Root are considered be stronger than effects, yet limited. Here, we focus on group 11 stress-resistant We found...
Citrus reticulata Blanco cv. Shiyue Ju, which produces one of China's most popular tropical fruits, is widely planted throughout southern China. In 2008, a new citrus disease was found in Zhaoqing City Guangdong Province on about 20,000 ha. Yield losses averaged 15% wide range different aged trees C. Ju. No yield were observed Gong gan. Symptoms first appeared young leaves as leaf lesions, reddish-brown, elliptical, and 2 to 5 mm diameter. After several weeks, 20 70% dropped 10 50% fruits...
SUMMARY Idiopathic nonobstructive azoospermia (INOA) is one of the most severe forms male infertility, yet its pathophysiology remains unclear. WT1 (Wilms’ tumor 1) regulates polarity Sertoli cells, thereby playing a critical, indirect role in spermatogenesis. Here, we evaluated gene variation associates with INOA by assessing promoter and coding regions 200 patients diagnosed proven‐fertile men. Three novel variants region were detected only patients, including two synonymous missense...
Plant disease is an important factor that affects the plant microbiome. However, for many plant–pathogen–microbiome interactions, influences are unknown. Citrus, comprising abundant varieties of mandarin, sweet orange, pomelo, and lemon, widely cultivated in different production areas China. Most these vulnerable to citrus canker, which caused by Xanthomonas spp. In this study, asymptomatic cankered leaves from canker-infected trees, respectively, were collected 17 orchards six their...
For perennial plants, newly emerged organs are fresh hot spots for environmental microbes to occupy and assemble form mature microbial communities. In the community, some commensal fungi can play important roles in succession, thus significantly improving host plant growth disease resistance. However, their participating patterns assembly succession remain largely unknown. this study, we profiled fungal community found a similar pattern of spring-emerged leaves from March October two pomelo...
Anthracnose fruit rot of litchi (Litchi chinensis Sonn.), caused by Colletotrichum spp., has been mainly associated with the C. acutatum species complex and gloeosporioides (Farr Rossman 2020). In June 2010, isolates were isolated together from anthracnose lesions on fruits (cv. Nuomici) obtained a orchard in Shenzhen (N 22.36°, E 113.58°), China. The symptoms typically appeared as brown up to 25 mm diameter, causing total sometimes cracking. Based number we collected, appears less...
In the spring of 2011, leaf and fruit spot symptoms were observed in three orchards planted with Citrus reticulata Blanco cv. Nian Ju Longmen City, Guangdong Province. The incidence ranged from 5 to 25% across all orchards. Similar not on C. Shiyue at same Lesions diseased leaves first emerged lower portions trees initially small, circular, diffuse distribution over surface. Within 2 weeks, small circular spots enlarged brown sunken necrotic lesions ranging 30 mm diameter. To isolate causal...
Fusarium species have been identified as pathogens causing many different plant diseases, and here we report an emerging banana leaf blight (BLB) caused by F. sacchari ( Fs ) discovered in Guangdong, China. From the symptomatic tissues collected field, a fungal isolate was obtained, which induced similar symptoms on healthy seedlings after inoculation. Koch’s postulates were fulfilled re-isolation of pathogen. Phylogenetic analysis two gene segments whole genome sequence pathogen belonging...
Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is the primary vector of Candidatus Liberibacter asiaticus (Las), which responsible for Huanglongbing (HLB), most devastating disease affecting Asian citrus. A fungal strain isolated from Guangdong citrus groves that infects D. adults was and characterized, morphological genetic data identified this pathogen as Paecilomyces variotii. The fungus able to infect healthy D.citri cause a phenotype similar observed in field, fulfilling Koch’s...
Guava (Psidium guajava L.), a nutrient-rich and economically significant fruit, is extensively cultivated in southern China. In six continuous years (from 2018 to 2023), dark-purple rotted guava with sunken lesion were observed on trees (variety 'Zhenzhu', aged over 5 years) Dongguan Panyu districts, Guangdong Province. Annually, the incidence of fruit rot disease affected fields reached 30% 50% significantly reduced yield quality harvest guava. The initial symptoms epicarp fruits black,...
Coptis (Coptis chinensis) belongs to the Ranunculaceae family, rhizomes used in traditional Chinese medicine. Since 2021, an uncommon stem and leaf wilt disease, with average disease incidence of 70%~90%, has been observed Guangdong Guangxi provinces. The early symptoms were on older leaves stems, whole seedling wilted died. rhizome diseased seedlings changed color, became necrotic, rotted. Symptomatic roots stems surface-sterilized 70% ethanol for 30 s, followed by 0.2% NaClO 2-3 min,...
Citrus reticulata Blanco cv. Nian Ju, an important ornamental plant, is traditionally displayed during the Chinese Spring Festival because its golden fruits are a symbol of auspiciousness. In spring 2012, foliar blight was observed on 10 to 30% Ju plants at four nurseries in Yangjiang, Guangdong Province, China. Initial symptoms appeared as brown black lesions, followed by expansion spots into blight. Some young branches also had necrosis. During frequent rainfall and prolonged wet periods...

The secretion of root exudates modulates the nutritional state rhizosphere area, further selecting specific bacteria taxa shaping communities. Many studies effects have demonstrated that selection by consistently enriches a set taxa, this is conserved across different species.
