TL;DR
This study explores how tobacco plants respond at the molecular level to boron deficiency by analyzing gene and protein expression changes.
Contribution
The study provides new insights into the molecular mechanisms of tobacco's response to boron deficiency through integrative transcriptome and proteome analysis.
Findings
B deficiency caused morphological and physiological disorders in tobacco seedlings.
The NIP5;1-BORs module and antioxidant machinery were up-regulated under B deficiency.
Cell wall metabolism-related genes and proteins showed complex regulation in response to B levels.
Abstract
Boron (B) is an essential micronutrient for plants. Inappropriate B supply detrimentally affects the productivity of numerous crops. Understanding of the molecular responses of plants to different B supply levels would be of significance in crop improvement and cultivation practices to deal with the problem. We conducted a comprehensive analysis of the transcriptome and proteome of tobacco seedlings to investigate the expression changes of genes/proteins in response to different B supply levels, with a particular focus on B deficiency. The global gene and protein expression profiles revealed the potential mechanisms involved in the responses of tobacco to B deficiency, including up-regulation of the NIP5;1-BORs module, complex regulation of genes/proteins related to cell wall metabolism, and up-regulation of the antioxidant machinery. Our results demonstrated that B deficiency caused…
