Abstract

This paper is try to investigate the molecular mechanisms of cadmium (Cd) response in mulberry (Morus alba L.) leaf. Transcriptome sequencing technology is used to analyze the profiles of low-Cd mulberry Zhehulusang (zhls) and high-Cd mulberry Xianmianzao (xmz) under Cd stress. Approximately 195 million clean reads were obtained, 2785 and 1211 differentially expressed genes (DEGs) were identified in zhls and xmz. The DEGs of zhls enriched in the pathway of flavonoid biosynthesis, photosynthesis, carbon fixation in photosynthetic organisms. The DEGs of xmz enriched in the pathway of flavonoid biosynthesis, plant-pathogen interaction, phenylpropanoid biosynthesis. Through comparative analyses, the flavonoids may be the effective antioxidants conserved in mulberry under Cd stress. These information may be useful for further studies on investigating the molecular mechanisms of mulberry response to Cd stress.

镉胁迫下两个桑树品种的转录组分析谱比较

摘要

本文试图探讨镉的分子机制（CD）响应桑树（桑白皮L.）叶。转录组测序技术用于分析镉胁迫下低镉桑Z杂桑（zhls）和高镉桑X鲜枣（xmz）的概况。获得了大约1.95亿次纯净读取，在zhls和xmz中鉴定了2785和1211个差异表达基因（DEG）。zhls的DEG丰富了光合生物中类黄酮的生物合成，光合作用和碳固定途径。xmz的DEG丰富了黄酮类生物合成，植物-病原体相互作用，苯丙烷类生物合成的途径。通过比较分析，类黄酮可能是镉胁迫下桑树中保守的有效抗氧化剂。这些信息可能有助于进一步研究桑树对镉胁迫的分子机制。
