Lw-1 Induced Resistance to Tmv in Tobacco Was Mediated by Nitric Oxide and Salicylic Acid Pathway

Hongyan Zhang Guojie Jin Jing Zhang Yueyang Zhang Baowei Gao

This study investigated the mechanism of LW-1-induced resistance to TMV by using wild-type and salicylic acid (SA)-deficient NahG transgenic tobacco. The results showed that LW-1-induced tobacco resistance to TMV disappeared in the NahG plants, and that the increase in salicylic acid that is elicited by LW-1 also vanished in NahG. Meanwhile, we found that LW-1 induced defense-related early-signaling generation of nitric oxide (NO), and NO fluorescence emerged in both types of tobacco treated by LW-1, although NO fluorescence was stronger in NahG than in wild-type tobacco. Both of them were eliminated by the NO scavenger cPTIO. which also reversed LW-1-induced anti-TMV activity and the increase in SA content, suggesting that NO participates in LW-1-induced resistance to TMV, and that NO may be upstream of the SA pathway. Defense-related enzymes and genes were detected in tobacco with or without TMV inoculation, and the results showed that LW-1 regulates both enzyme activity (3-glucanase [GLU], catalase [CAT] and phenylalanine ammonia-lyase [PAL]) and gene expression (PR1, PAL, WYKY4) through NO signaling in both SA-dependent and SA-independent pathways.

Highly‐efficient colony PCR method for red yeasts and its application to identify mutations within two leucine auxotroph mutants

Yeast (2012)

Xinping Lin Fan Yang Yongjin J. Zhou Zhiwei Zhu Guojie Jin

Red yeasts hold great promise in the production of microbial lipids and carotenoids. Genetic study of red yeasts has attracted much attention; however, rapid amplification of genes from red yeast samples remains technically challenging. Here a highly efficient method for the preparation of genomic DNA (gDNA) template, which could be directly used for PCR, was developed. Cells from colonies or liquid cultures were collected and sequentially treated by microwave, plMAN5C, proteinase K and boiling (MMPB) in a single tube to give cell lysates that were qualified as PCR templates. Single-copied gDNA fragments o up to 2.8 kb were successfully amplified. We also demonstrated successful application of this method for species in the Ascomycetes and Basidiomycetes and identification of two leucine auxotroph mutants of Rhodotorula glutinis. This method could be widely employed for the screening and genetic engineering of various yeasts.

A multi-omic map of the lipid-producing yeast Rhodosporidium toruloides

Nature Communications (2012)

Zhiwei Zhu Sufang Zhang Hongwei Liu Hongwei Shen Xinping Lin

Triacylglycerols are among the most attractive alternative raw materials for biofuel development. Current oil plant-based technologies are limited in terms of triacylglycerol production capacity and rate. These limitations may be circumvented by biotransformation of carbohydrates into lipids; however, our understanding of microbial oleaginicity remains limited. Here we present the results of a multi-omic analysis of Rhodosporidium toruloides, a robust triacylglycerol-producing fungus. The assembly of genome and transcriptome sequencing data reveals a genome of 20.2 Mb containing 8,171 protein-coding genes, the majority of which have multiple introns. Genes including a novel fatty acid synthase are predicted to participate in metabolic pathways absent in non-oleaginous yeasts. Transcriptomic and proteomic data suggest that lipid accumulation under nitrogen-limited conditions correlates with the induction of lipogenesis, nitrogenous compound recycling, macromolecule metabolism and autophagy. The multi-omic map of R. toruloides therefore provides a valuable resource for efforts to rationally engineer lipid-production pathways. The ability of oleaginous fungi to produce lipids for biofuels remains untapped, in part due to a lack of genetic information required to engineer industrial strains. Zhuet al. present the genome of R. toruloides, and identify transcriptomic and proteomic changes associated with lipid production.
