Abstract: In order to preliminarily explore the differential gene expression between Sorghum sudanense (Piper) Stapf. and Sorghum bicolor (Linn.) Moench.×Sorghum sudanense (Piper) Stapf. Perform,their transcriptome was sequenced and the expression of differential genes related to tillering regulation,crude protein and lignin synthesis was analyzed in this study. The results showed that compared with S. sudanense (Piper) Stapf.,the number of tillers (NT) per plantlets of S. bicolor (Linn.) Moench.×S. sudanense (Piper) Stapf. Perform significantly reduced,and the contents of crude protein (CP),lignin (LN),and monolactone (SLs),as well as the activities of fructose kinase (FRK),phenylalanine ammonia lyase (PAL),polyphenol oxidase (PPO),trans cinnamate 4-monooxygenase (C4H) significantly increased. Hexokinase 3 (HXK3),fructose kinase 2 (FRK2) gene,aspartate aminotransferase (ASPAT) gene,S-adenosylmethionine synthetase 1 (SAMS1) gene,polyphenol oxidase II (PPOII) gene,bifunctional aspartate kinase/homoserine dehydrogenase 2 (AKI/DHI2) gene,phenylalanine ammonia lyase (PAL) gene,trans cinnamate 4-monooxygenase (C4H) gene upregulated,while the expression of the monolithine esterase D14 (SLsE D14) gene downregulated;This study lays the foundation for the cloning and molecular marker development of functional genes related to S. sudanense (Piper) Stapf. and S. bicolor (Linn.) Moench.×S. sudanense (Piper) Stapf. Perform.

摘要: 为了初步探明苏丹草[Sorghum sudanense (Piper) Stapf.]和高丹草[Sorghum bicolor (Linn.) Moench.×Sorghum sudanense (Piper) Stapf.]相关差异基因的表达,本研究对两者进行转录组测序,并对分蘖调控以及粗蛋白和木质素合成关联基因的差异表达进行分析。结果表明:与苏丹草相比,高丹草的单株分蘖数显著降低,粗蛋白、木质素和独角金内酯含量以及果糖激酶、苯丙氨酸解氨酶、多酚氧化酶、反肉桂酸4-单加氧酶活性显著提高,己糖激酶-3(HXK3)、果糖激酶2(FRK2)、天冬氨酸转氨酶(ASPAT)、S-腺苷甲硫氨酸合成酶1(SAMS1)、多酚氧化酶II(PPOII)、双功能天冬氨酸激酶/高丝氨酸脱氢酶2(AKI/DHI2)、苯丙氨酸解氨酶(PAL)、反-肉桂酸4-单加氧酶(C4H)基因表达上调,独角金内酯酯酶D14(SLsE D14)基因表达下调。本研究为苏丹草和高丹草相关功能基因的克隆、分子标记开发等工作奠定了基础。
