网页2018年2月21日 · 本文报道了系统素的感知主要依赖于一对lrr-rk同源基因，即syr1和syr2。 其中，SYR1作为主要的系统素受体，该蛋白与系统素具有高度亲和并且特异的结合能力。
The systemin receptor SYR1 enhances resistance of tomato
网页2018年2月19日 · Treatment of tomato (Solanum lycopersicum) and other Solanum species with systemin induces an array of defence-related responses, including the accumulation of proteinase inhibitors (PINs), an ...
Systemin-mediated long-distance systemic defense responses
网页2020年2月21日 · We highlight recent advances in systemin research, which elucidated how cells integrate multiple long-distance signals into the systemic defense response. In addition, we discuss the perception of systemin by SYR1 and its …
Systemin – a polypeptide defense signal in plants - Schaller
网页A search for signal molecules involved in both the localized and distal signalling has resulted in the identification of an 18-amino-acid polypeptide, called systemin, that activates defense genes in leaves of tomato plants when supplied at levels as low as fmols/plant.
Systemin-植物中的多肽防御信号,BioEssays - X-MOL - X-MOL科学 ...
网页Systemin及其前体prosystemin为多肽激素可能在信号化环境胁迫反应以及调节植物生长和发育中发挥广泛作用的新兴可能性提供了原型。. 而是一种弗林蛋白酶样蛋白酶，可将systemin切割成较小的多肽。. Systemin及其前体prosystemin为多肽激素可能在信号化环境胁 …
Systemin/Jasmonate-mediated systemic defense signaling in …
网页Previously, it has been proposed that systemin is the long-distance mobile signal for defense gene expression. Recently, grafting experiments with tomato mutants defective in JA biosynthesis and signaling provide new evidence that JA, rather than systemin, functions as the systemic wound signal, and that the biosynthesis of JA is regulated by ...
Systemin肽应用提高番茄盐胁迫耐受性并揭示植物对生物和非生物 …
网页Here we report that a soil drench picomolar solution of systemin increases tomato salt stress tolerance by i) activating of transporters in leaves ii) enhancing the cellular antioxidant power, and iii) balancing the protease activity induced by salt stress.
网页Systemin, a peptide plant hormone of 18 amino acids, coordinates local and systemic immune responses. The activation of the canonical systemin-mediated systemic signaling pathway involves systemin release from its precursor prosystemin, systemin binding to its membrane receptor SYSTEMIN RECEPTOR1 (SYR1), …
