逆境胁迫下食用菌转录组学研究进展

Research Progress on Transcriptome of Edible Fungi Under Adversity Stress

食用菌统称蘑菇,是子实体硕大可供食用的大型真菌,是一种重要的特色经济作物,富含蛋白质、多糖、维生素、膳食纤维等多种营养成分,具有较高的食用和药用价值。逆境胁迫是影响食用菌生长发育、产量及品质的重要因素,因此食用菌应答逆境胁迫的分子机制受到越来越多的重视与关注。转录组学作为功能基因组学的重要组成部分,有助于在整体水平上研究细胞中基因转录的情况及转录调控规律。利用该技术研究逆境胁迫下食用菌基因表达情况,有利于阐明食用菌在逆境胁迫环境下的分子应答机制。该研究介绍了应用转录组学技术研究食用菌应答生物胁迫和非生物胁迫(温度、光照、盐碱、重金属等)的进展,以期为食用菌抗逆分子机理的研究提供参考依据。

Edible fungi,collectively known as mushrooms,are large fungi that can be eaten by fruiting bodies.It is an important characteristic cash crop,rich in protein,polysaccharides,vitamins,dietary fiber and other nutrients,and has high edible and medicinal value.Stress is an important factor affecting the growth,yield and quality of edible fungi.Therefore the molecular mechanism of edible fungi responding to stress has received more and more attention.Transcriptome,as an important part of functional genomics,contributes to study gene transcription and regulation in cells at the overall level.Using this technology to study the gene expression of edible fungi under stress is conducive to clarifying the molecular response mechanism of edible fungi under stress.In this study,progress in the application of transcriptome technology to study the response of edible fungi to biological and abiotic stresses(temperature,light,heavy metals,saline,etc.),in order to provide reference for the study of molecular mechanism of stress resistance of edible fungi.
