Bean common mosaic virus (BCMV) was detected on common bean (Phaseolus vulgaris) plants showing wrinkled and/or narrow leaves, curling, shrinking and chlorosis of leaves, dwarfing of plants, and mottled pods in Inner Mongolia and named BCMV-22Huhe. Its genome has a size of 10,062 bp and was deposited in GenBank under the accession number OR778613. It is closely related to BCMV-Az (GenBank accession no. KP903372, in China) in the lineage of AzBMV. A recombination event was detected for BCMV-22Huhe among the 99 BCMV isolates published in the NCBI GenBank database, showing that BCMV-CJ25 (MK069986, found in Mexico) was a potential major parent, and the minor parent is unknown. This work is the first description of the occurrence of BCMV in Inner Mongolia, China. [ABSTRACT FROM AUTHOR]

Abstract: Potato (Solanum tuberosum L.) is globally the fourth largest staple crop after rice, wheat and maize. China is the largest potato producer worldwide, accounting for 26.3% and 22.2% of the global total area and yield, respectively. Viral diseases have been a limiting factor for sustainable production of potato in China. This article provides update and comprehensive information on the most important viruses, their effect on yield and their control in China. Meristem culture is currently the most widely used technique for production of virus-free potato plants and these plants are used as nuclear stock for the production of certified seed tubers. Although a significant increase in tuber yield has been achieved using certified seed potatoes, lack of application of a national seed potato production scheme has hindered progress. Conventional breeding using virus-resistant cultivars introduced from other countries as parents has already led to the production of Chinese cultivars. Use of virus-resistant wild Solanum species and genetic transformation techniques will provide new virus-resistant varieties in the future to further enhance control of potato viruses in China.

• The antimicrobial cationic acrylate-based copolymer (PAMs) was facilely synthesized via soap-free emulsion polymerization. • I PAMs exhibited excellent antibacterial properties based on quaternary ammonium compound of polymer chains. • Owing to effective combination between the inorganic filler and PAMs, the coatings are better than that of single materials. • The PAMs coating couldn't only decorate walls, but also improve environmental hygiene. Microorganism contamination on substrate surfaces is arousing increasingly concern as a serious health issue. In this study, we described fabricating antimicrobial cationic acrylate-based composite and investigating it as antimicrobial coatings of interior walls in buildings. Firstly, utilizing 3-(methacryloylamino) propyltrimethyl ammonium chloride (MPAC) and acrylates (BA, MMA) as monomers, a novel antimicrobial cationic acrylate-based copolymers (PAMs) was synthesized from surfactant-free emulsion polymerization (SfEP). The synthesis conditions, structures and physical properties of copolymers (PAMs) and its film (PAMs-F) were investigated through FT-IR, SEM, TEM and scratch test, etc. The results revealed that 6 % of MPAC and 0.5 % of KPS enabled the film-forming properties and enhanced conversion rate of PAMs, as well as endowed PAMs-F with significant antimicrobial activity. Furthermore, the PAMs based coating (PAMs-C) was prepared by PAMs and inorganic fillers. And the antimicrobial activity of PAMs-F and PAMs-C was measured, the effects of cationic monomer and nano-TiO 2 were also investigated. The results indicated that PAMs-C was able to use to protect the building interior wall from microbial contamination. [ABSTRACT FROM AUTHOR]
