TL;DR
This study identifies and analyzes sugar transporter genes in wheat to understand their role in resistance to Fusarium head blight, a major wheat disease.
Contribution
The study identifies a new STP gene and reveals differential expression patterns of 11 STP genes in response to FHB-related stressors.
Findings
50 TaSTP genes showed differential expression under biotic or abiotic stress.
11 TaSTP genes were differentially expressed after treatment with chitin, Fusarium graminearum, or deoxynivalenol.
TaSTP26-5A was 28-fold upregulated to chitin in 'Yangmai 158' compared to 'Fielder'.
Abstract
Fusarium head blight (FHB) negatively affects wheat yield and quality worldwide. As wheat varieties differ in terms of their resistance to FHB, the identification of FHB-resistant genes is of great importance for the genetic improvement for FHB resistance in wheat breeding. Although sugar transporter proteins (STPs) play vital roles in plant–pathogen interactions, the functions of STP genes in wheat FHB resistance remain poorly understood. In this study, bioinformatics analyses were conducted to identify novel STP genes and characterize their expression profiles in wheat. We confirmed the presence of the 81 TaSTP genes previously reported and identified one additional member, designated as TaSTP6-2D. Based on RNA-seq profiles, 50 TaSTP genes that showed differential expression under biotic or abiotic stress were selected to explore the potential function in the resistance to Fusarium…
