Identification and Analysis of <I>PGM</i> and <I>SUS</i> Gene Families in Leymus Chinensis Seed Transcriptome

Leymus chinensis ( &nbsp;(Trin.) Tzvel.)&nbsp;is a good perennial forage with palatability, high yield and feeding value. In addition, because of its strong resistance, can improve the disadvantaged environment such as poor land, it is an important species to protect grassland ecology in China.&nbsp;Therefore, order promote germination leymus seeds explore mechanism Germination, this study used sterile water treatment control, exogenous GA3 conditions. Based on analysis pre-transcriptome data, was determined that&nbsp; PGM &nbsp;and&nbsp; SUS &nbsp;genes sucrose starch metabolic pathways play significant role seed Germination.&nbsp;Members identification, conserved domains, evolutionary trees were analyzed for both gene families using bioinformatics method. The expression pattern of&nbsp; FPKM results showed that 7 members selected from each the&nbsp; &nbsp;families based data Chinensis transcriptome. molecular weight ranged 15 471.3 67 912.9 Da, isoelectric point value 4.45 6.31, showing weak acidity.&nbsp; &nbsp;family are hydrophilic stable proteins. 30 421.5 110 262.9 Da. neutral except&nbsp; LcSUS1,5 , while other four genes acidic.&nbsp; LcSUS4 6 &nbsp;were proteins, rest unstable The&nbsp; and&nbsp; &nbsp;gene enzyme promoting synthesis metabolism pathways. GA3-treated promoted of&nbsp;Leymus chinensis&nbsp;seeds by regulating different levels.
