Abstract

By characterizing the cell wall proteomes of different sugarcane organs (leaves and stems) at two developmental stages (young vs mature/apical vs basal), it is possible to address unique characteristics in each of them. Four-month-old leaves show a higher proportion of oxido-reductases and proteins related to lipid metabolism (LM), besides a lower proportion of proteins acting on polysaccharides, in comparison to 4-month-old internodes. It is possible to note that sugarcane leaves and young stems have the highest LM rate than all species, which is assumed to be linked to cuticle formation. The data generated enrich the number of cell wall proteins (CWPs) identified in sugarcane, reaching 277. To our knowledge, sugarcane has now the second higher coverage of monocot CWP in plants.

摘要

通过对不同甘蔗器官（叶片和茎）在两个发育阶段（幼龄与成熟/顶生与基生）的细胞壁蛋白质组进行特征分析，可以了解它们各自的独特特征。与 4 个月大的节间相比，4 个月大的叶片具有更高比例的氧化还原酶和与脂质代谢（LM）相关的蛋白质，而作用于多糖的蛋白质比例较低。可以注意到，与所有物种相比，甘蔗叶片和幼茎的 LM 速率最高，这被认为与角质层形成有关。生成的数据丰富了甘蔗细胞壁蛋白质（CWPs）的鉴定数量，达到 277 种。据我们所知，甘蔗现在是植物中单细胞 CWPs 覆盖率第二高的物种。
