Abstract The genome of the soybean pathogen Phytophthora sojae contains nearly 400 genes encoding candidate effector proteins carrying host cell entry motif RXLR-dEER. Here, we report a broad survey transcription, variation, and functions large sample P. effectors. Forty-five (12%) showed high levels polymorphism among isolates significant evidence for positive selection. Of 169 effectors tested, most could suppress programmed death triggered by BAX, effectors, and/or PAMP INF1, while...
Recently, many Deep Learning models have been employed to classify different kinds of plant diseases, but very little work has done for disease severity detection. However, it is more important master the severities diseases accurately and timely, as helps make effective decisions protect plants from being further infected reduce financial loss. In this paper, based on Huanglongbing (HLB)-infected leaf images obtained PlantVillage crowdAI, we created a dataset with 5,406 citrus by HLB. Then...
Many bacterial, fungal, and oomycete species secrete necrosis ethylene-inducing peptide 1 (Nep1)-like proteins (NLP) that trigger programmed cell death (PCD) innate immune responses in dicotyledonous plants. However, how NLP induce such is not understood. Here, we show silencing of the MAPKKKα-MEK2-WIPK mitogen-activated protein kinase (MAPK) cascade through virus-induced gene compromises hydrogen peroxide accumulation PCD induced by Nep1(Mo) from Magnaporthe oryzae. WIPK interacts with...
Pyruvate kinase (PK), a pivotal enzyme in glycolysis, serves as multifunctional regulator of plant growth, development, and stress adaptation. Despite its significance, the functional roles PKs peanut remain largely unexplored. Here, we performed genome-wide identification systematic characterization PK genes cultivated peanut, identifying 21 AhPK (AhPK1–AhPK21). Phylogenetic classification divided these into two subfamilies: PKc (comprising PKc-1 PKc-2 subgroups) PKp PKp-α PKp-β subgroups)....
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...
Citrus production is severely threatened by the devastating Huanglongbing (HLB) disease globally. By studying and analyzing defensive behaviors of an HLB-tolerant citrus cultivar 'Shatangju', we discovered that can sense Candidatus Liberibacter asiaticus (CLas) infection induce immune responses against HLB, which be further strengthened both endogenously produced exogenously applied methyl salicylate (MeSA). This circuit turned on miR2977-SAMT (encoding a Salicylate [SA] O-methyltransferase)...
Huanglongbing (HLB) is a destructive citrus bacterial disease caused by Candidatus Liberibacter asiaticus (Ca.Las) and cannot be cured current pesticides. Root lesion Tylenchulus semipenetrans juveniles were observed in HLB-affected tree roots. We hypothesize that root treatment with fosthiazate (FOS) Cupric-Ammonium Complex (CAC) will improve the growth inhibit HLB. CAC broad spectrum fungicide can promote of crops. FOS kills protects roots from damage harmful bacteria such as Ca.Las. After...
Citrus Huanglongbing (HLB), caused by the phloem-inhibiting bacterium Candidatus Liberibacter asiaticus (CLas), is most devastating citrus disease, intimidating production worldwide. Although commercially cultivated cultivars are vulnerable to CLas infection, HLB-tolerant attributes have, however, been observed in certain varieties, suggesting a possible pathway for identifying innate defense regulators that mitigate HLB. By adopting transcriptome and small RNAome analysis, current study...
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...
Although several protocols for genetic transformation of citrus have been published, it is highly desirable to further improve its efficiency. Here we report treatments Agrobacterium cells and explants prior during co-cultivation process enhance efficiency using a commercially used rootstock 'Carrizo' citrange [Citrus sinensis (L.) Osb. × Poncirius trifoliata Raf.] as model plant. We found from light-grown seedlings exhibited higher than those etiolated seedlings. pre-cultured in 1/10 MS,...
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...
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...
A brown leaf spot disease was observed on Chinese bayberry (Myrica rubra) in Zhejiang Province, China during 2012 and 2014. fungus isolated from diseased leaves showing typical symptoms of spot. The pathogenicity the confirmed through inoculation experiments. Based morphological characteristics molecular analyses, pathogen identified as Pestalotiopsis clavispora (G. F. Atk.) Steyaert. This is first report P. causing China.
In this study, two polyclonal antibodies were produced against the Omp protein of 'Candidatus Liberibacter asiaticus'. First, omp genes sequenced to exhibit 99.9% identity among 137 isolates collected from different geographical origins. Then, peptides containing hydrophobic polypeptide-transport-associated (POTRA) domain and β-barrel domain, respectively, identified on protein. After that, these overexpressed in Escherichia coli purified by affinity chromatography immunize white rabbits....
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...

The most serious citrus postharvest diseases are green mould caused by Penicillium digitatum and blue italicum. Marine microorganisms have become a new measure in the control of these diseases. In this study, we isolated 56 marine actinomycetes, strain AM-4 from Drupa granulata exhibited strongest antagonistic activity against P. digitatum. Molecular, morphological, cultural physio-biochemical analysis identified as Streptomyces chumphonensis. Strain also 11 other phytopathogens, with an...
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...
