Comparative Transcriptome Analysis Reveals Key Genes and Pathways Associated with Phosphate-Sensitive Behaviors in Cunninghamia lanceolata (Lamb.) Hook.

Cunninghamia lanceolate (Lamb.) Hook. (Chinese fir) is one of the most important wood-producing species, supplying ~20% commercial timber by plantations in China. However, genetic potential bred variety limited soil degrading long term and requiring continuous replanting, especially shortage supply active efficient phosphorus. Recently, great attention has been paid to genotypic variation phosphorus conversion utilization efficiency tree breeders. In this study, morphological characteristics were used evaluate Chinese fir clonal Pi-efficiency stress. A Pi-tolerant clone a Pi-sensitive selected for RNA sequencing, respectively. addition, gene function annotation weighted correlation network analysis (WGCNA) performed. total 60 hub genes selected, combining phosphate accumulation under Pi-deficiency We also RNA-seq data analyze differences response clones stress, real-time quantitative polymerase chain reaction (RT-PCR) analyses test validity transcriptome data. The present study provided new insights into molecular mechanisms Pi-efficient clones.
