Analysis of nrLSU gene to support identification of fungus belonging to cordyceps genus and clavicipitaceae familyWe have successfully applied molercular biology in combination with bioinformatics for nrLSU to assist the entomopathogenic sample DL0004. The resolution of the analysis process was to the species level and identical with ITS analysis. Moreover, this methodology can be applied for other samples of the collection.

Isolating the monokaryon collection of Pleurotus sppFollowing morphology and phylogenetic analysis, 9 Pleurotus strains were identified. PL1 is P. citrinopileatus; PL2, PL6, PL9 are P. ostreatus; PL3 is P. cystidiosus; PL4, PL8 are P. pulmonarius; PL5 is P. cornucopiae; and PL7 is P. incarnatus. Genetic analysis by AFLP showed that diversity of those strains is high which similarity score from 0....

Screening of salt tolerant Bacteria for plant growth promotion activities and biological control of rice blast and sheath blight disease on mangrove riceFour isolates with highest antifungal activity were evaluated of biocontrol on rice growing experiment. The result shown in Table 2 indicated that the abilities to control sheath blight in N- 2C1, N-LĐ5 treatment were the higher (40.59 % and 39.06 %, respectively) and had significant differences compared to LS6 (31.46 %). It was similar with a p...

Tạo chủng vi khuẩn escherichia coli biểu hiện tái tổ hợp cis-Prenyltransferase 1 có khả năng tổng hợp neryl pyrophosphate - La Ngọc Thùy VânSUMMARY Neryl pyrophosphate (NPP), also known as neryl diphosphate (NDP), is the cis isomer of genaryl pyrophosphate (GPP). Previously, it has been shown that monoterpene synthases found in plants use GPP as a substrate for the synthesis of monoterpenes and monoterpenoids. However, in 2009, Schilmiller identified a new monoterpene synthase gene ...
