摘要

与气候变化相关的环境胁迫会对作物生产力产生负面影响,并对可持续农业构成威胁。植物具有非凡的先天能力,能够检测到广泛的环境线索,包括触发胁迫诱导调控网络和信号通路的胁迫。植物致病相关-1(PR-1)蛋白的转录激活首次被确定为系统获得性抗逆的一个组成部分。与它们在免疫防御中的核心作用相一致,PR-1 在不同植物物种中的过表达经常被用作水杨酸(SA)介导的防御反应的标记。最近的研究进展表明了毒力效应因子、水杨酸信号级联和表观遗传修饰如何在环境胁迫下调节 PR-1 的表达。我们和其他研究人员发现,涉及 PR-1s 的转录调控网络可用于提高植物对胁迫的恢复能力。这些研究结果为该领域注入了新的活力,并为人们提供了期待已久的关于 PR-1s 在极端环境胁迫下可能发挥的功能的见解。

Pathogenesis related-1 proteins in plant defense: regulation and functional diversity.

Climate change-related environmental stresses can negatively impact crop productivity and pose a threat to sustainable agriculture. Plants have a remarkable innate ability to detect a broad array of environmental cues, including stresses that trigger stress-induced regulatory networks and signaling pathways. Transcriptional activation of plant pathogenesis related-1 (PR-1) proteins was first identified as an integral component of systemic acquired resistance in response to stress. Consistent with their central role in immune defense, overexpression of PR-1s in diverse plant species is frequently used as a marker for salicylic acid (SA)-mediated defense responses. Recent advances demonstrated how virulence effectors, SA signaling cascades, and epigenetic modifications modulate PR-1 expression in response to environmental stresses. We and others showed that transcriptional regulatory networks involving PR-1s could be used to improve plant resilience to stress. Together, the results of these studies have re-energized the field and provided long-awaited insights into a possible function of PR-1s under extreme environmental stress.

期刊介绍: Biotechnological techniques, from fermentation to genetic manipulation, have become increasingly relevant to the food and beverage, fuel production, chemical and pharmaceutical, and waste management industries. Consequently, academic as well as industrial institutions need to keep abreast of the concepts, data, and methodologies evolved by continuing research. This journal provides a forum of critical evaluation of recent and current publications and, periodically, for state-of-the-art reports from various geographic areas around the world. Contributing authors are recognized experts in their fields, and each article is reviewed by an objective expert to ensure accuracy and objectivity of the presentation.
