阿拉伯半乳聚糖蛋白（AGPs）包含一个富含羟基脯氨酸的糖蛋白家族，与植物生长发育有关。在本研究中，从水稻基因组中鉴定出69个AGPs，包括13个经典AGPs， 15个阿拉伯半乳聚糖（AG）肽，3个非经典AGPs， 3个早期结节样AGPs (enod样AGPs)， 8个非特异性脂质转移蛋白样AGPs （nsltp样AGPs）和27个束状霉素样AGPs （FLAs）。表达的序列标签、微阵列和大规模平行标记测序标签的结果用于分析agp编码基因的表达，并通过实时PCR证实。结果表明，水稻agp编码基因主要在花药中表达，并在脱落酸、赤霉素酸和非生物胁迫下表现出不同的表达模式。基于这一分析结果，我们试图将水稻agp编码基因的蛋白质结构和表达模式与其功能联系起来。综上所述，水稻AGP基因家族的全基因组鉴定和表达分析为进一步研究水稻AGP的功能提供了基础。
Arabinogalactan proteins (AGPs) comprise a family of hydroxyproline-rich glycoproteins that are implicated in plant growth and development. In this study, 69 AGPs are identified from the rice genome, including 13 classical AGPs, 15 arabinogalactan (AG) peptides, three non-classical AGPs, three early nodulin-like AGPs (eNod-like AGPs), eight non-specific lipid transfer protein-like AGPs (nsLTP-like AGPs), and 27 fasciclin-like AGPs (FLAs). The results from expressed sequence tags, microarrays, and massively parallel signature sequencing tags are used to analyse the expression of AGP-encoding genes, which is confirmed by real-time PCR. The results reveal that several rice AGP-encoding genes are predominantly expressed in anthers and display differential expression patterns in response to abscisic acid, gibberellic acid, and abiotic stresses. Based on the results obtained from this analysis, an attempt has been made to link the protein structures and expression patterns of rice AGP-encoding genes to their functions. Taken together, the genome-wide identification and expression analysis of the rice AGP gene family might facilitate further functional studies of rice AGPs.
