Sugarcane is one of the most important agricultural crops in the world. However, pathogen infection and herbivore attack cause constant losses in yield. Plants respond to pathogen infection by inducing the expression of several protein types, such as glucanases, chitinases, thaumatins, peptidase inhibitors, defensins, catalases and glycoproteins. Proteins induced by pathogenesis are directly or indirectly involved in plant defense, leading to pathogen death or inducing other plant defense responses. Several of these proteins are induced in sugarcane by different pathogens or insects and have antifungal or insecticidal activity. In this review, defense-related proteins in sugarcane are described, with their putative mechanisms of action, pathogen targets and biotechnological perspectives.
甘蔗是世界上最重要的农作物之一。然而,病原体感染和食草动物侵袭会持续导致产量损失。植物通过诱导多种蛋白质的表达来应对病原体感染,例如葡聚糖酶、几丁质酶、甜蛋白、肽酶抑制剂、防御素、过氧化氢酶和糖蛋白。病程相关蛋白直接或间接参与植物防御,导致病原体死亡或诱导其他植物防御反应。其中几种蛋白质在甘蔗中由不同病原体或昆虫诱导产生,并具有抗真菌或杀虫活性。在本综述中,描述了甘蔗中与防御相关的蛋白质,及其推定的作用机制、病原体靶点和生物技术前景。
