Morphological, Cultural, molecular and Pathogenic variation of Bipolaris sorokiniana in Wheat

American Journal of molecular Biology 2022年第4期12卷 190-202页

One hundred and twenty isolates of Bipolaris sorokiniana of wheat were isolated, identified and characterized based on morphological, cultural, pathogenic and ITS (Internal Transcribed Spacer) based molecular parameters. Collected isolates differed in respect of radial mycelial growth rate, color of the colony, surface texture of the colony, shape of the colony, conidia production ability and shape and color of conidia. ITS1 and ITS4 based PCR products yielded a species-specific band of 600 bp (base pairs) on agarose gel for the confirmation of B. sorokiniana. The mycelial growth rate of the isolates ranged from 1.39 to 4.46 mm/day. The septation of conidia ranged from 1.4 to 8.6. On the basis of conidia morphology, the isolates were grouped into five different groups, whereas the isolates were grouped into 12 cultural groups based on cultural characteristics. Cultural group 8 [CG (Cultural Group)-8] was the most virulent [38.5% LAD (Leaf area diseased)] and [CG (cultural Group)-4] was the less virulent [2% LAD (Leaf area diseased)] group among 12 groups when inoculated at tillering stage of wheat cv. Kachan.

Strawberry mottle virus(SMoV)is one of the most common viruses infecting strawberries,causing losses to fruit yield and *** this study,165 strawberry leaf samples were collected from six provinces of China,46 of which tested positive for *** complete genome sequences of 11 SMoV isolates were obtained from Liaoning(DGHY3,DGHY16-2,DGHY17,DGHY20-2,DGHY21,DGHY26-2),Shandong(SDHY1,SDHY5,SDHY31-2,SDHY33-2),and Beijing(BJMX7).The RNA1 and RNA2 nucleotide identities between the 11 Chinese isolates were 95.4-99.3%and 96.3-99.6%,respectively,and they shared 78.4-96.6%and 84.8-93.5%identities with the available SMoV isolates in *** analysis revealed that Chinese isolate SDHY33-2 and Canadian isolates Ontario and Simcoe were recombinants,and recombination events frequently occurred in the 3’UTR of *** analysis showed that in an RNA1 tree,most Chinese isolates clustered into the same group while isolate DGHY17 clustered into another group together with Czech isolate C and three Canadian *** an RNA2 tree,all Chinese isolates clustered into a single *** phylogenetic analysis based on nucleotide sequences was consistent with the results based on coat protein(CP)and RNA-dependent RNA polymerase(RdRp).Further evolutionary analysis indicated that negative selection drives SMoV evolution,and gene flow plays a major role in genetic ***,reassortment and recombination also influence the evolution of *** our knowledge,this is the first report of the complete genome of SMoV isolates from China and a detailed analysis of the SMoV population structure.

Intrahepatic cholangiocarcinoma(iCCA)can originate from the large bile duct group(segment bile ducts and area bile ducts),small bile duct group(septal bile ducts and interlobular bile ducts),and terminal bile duct group(bile ductules and canals of Hering)of the intrahepatic biliary tree,which can be histopathological corresponding to large duct type iCCA,small duct type iCCA and iCCA with ductal plate malformation pattern,and cholangiolocarcinoma,*** challenge in pathological diagnosis of above subtypes of iCCA falls in the distinction of cellular morphologies,tissue structures,growth patterns,invasive behaviors,immunophenotypes,molecular mutations,and surgical *** these reasons,this expert consensus provides nine recommendations as a reference for standardizing and refining the diagnosis of pathological subtypes of iCCA,mainly based on the 5th edition of the World Health Organization Classification of Tumours of the Digestive System.
