Comparative biochemical and transcriptome analyses in tomato and eggplant reveal their differential responses to Tuta absoluta infestation
Biochemical and gene activity differences in tomato and eggplant when attacked by Tuta absoluta
AI simplified
Abstract
Tomato shows significantly reduced concentrations of key biochemical compounds compared to eggplant after Tuta absoluta infestation.
- At 48 hours post-infestation, tomato exhibited lower levels of amino acids, fructose, sucrose, jasmonic acid, salicylic acid, and total phenols compared to eggplant.
- Transcriptome analysis indicated greater changes in gene expression in infested eggplant than in infested tomato.
- Signaling genes related to plant immunity, particularly those connected to salicylic acid, were significantly involved in eggplant's response to T. absoluta.
- Specific gene families, including PR1b1, NPR1, NPR3, MAPKs, and ANP1, appear to play vital roles in defending against T. absoluta infestation.
