Suppressing wheat sucrose phosphate synthase 1-B protects wheat against stripe rust.

ABSTRACT:

Introduction

Stripe rust caused by Puccinia striiformis Westend. f. sp. tritici (Pst) is a highly destructive wheat disease that threatens global food security. Pst extracts energy from wheat by interfering with photosynthesis, leading to significant yield losses. Redirecting metabolite flux to counteract pathogens remains a major challenge in enhancing crop resilience.

Objective

The primary objective of this study is to clarify the regulations of sucrose synthesis in wheat during its interaction with Pst, especially in relation to susceptibility and resistance response, and to supply genetic resources for breeding programs dedicated to ensuring food security.

Methods

Utilizing bulked segregant RNA sequencing (BSR-Seq), we identified and cloned a novel susceptibility
