Disease resistance and transcriptome analysis of Camellia oleifera induced by endophyte YYC155
To explore the mechanism of Camellia oleifera response to endophytic YYC155 inducing disease re-sistance,2-year-old C.oleifera was used as material to determine the biological control effect of YYC155 on an-thracnose of C.oleifera and the changes of disease resistance defense enzyme activity after induction,and RNA Seq technology was used to sequence and analyze the transcriptome of samples induced for 15 days.The results showed that YYC155 had a significant control effect on anthracnose of C.oleifera,which was 48.28%,and the defensive en-zyme activity was activated.Moreover,1655 differentially expressed genes(DEGs)were screened from CK vs YYC155 samples.DEGs were involved in biological processes,molecular functions and cell components in GO functions,and were enriched in 102 KEGG pathways,among which MAPK plant signal pathway,plant hormone sig-nal transduction,photosynthesis,and plant pathogen interaction were significantly enriched;In addition,resistance related genes AUX1,GID1,PP2C,JAR1,etc.were up-regulated.The above confirmed that YYC155 can better in-duce the disease resistance and defense system of C.oleifera,and it is a biocontrol endophytic strain with potential application value.
