Caleosins are involved in several cellular and biological processes that are closely associated with the synthesis, degradation and stability of oil bodies (OB). Because of the importance and the multiple roles of these OB-associated proteins, in silico identification of sequences corresponding to putative caleosins in the hazelnut genome has been performed, and the association with seed OB was verified using a proteomic approach. Five full-length sequences (CavCLO-H1, CavCLO-H2, CavCLO-H3, CavCLO-L1, CavCLO-L2), belonging to the two groups of caleosins (H and L), have been identified in the hazelnut genome. The number of identified caleosins is in agreement with that previously observed in other plant species, confirming that caleosins comprise small gene families in plants. A proteomic approach allowed us to verify only the presence of CavCLO-H1 in hazelnut OB, suggesting that several members inside this family could have different roles during plant growth and development. In silico analysis also suggests that CavCLO-H1 may act as a peroxygenase.

鉴定与榛子油（Corylus avellana L.）油体相关的caleosin。

Caleosins参与了几种与油体（OB）的合成，降解和稳定性密切相关的细胞和生物学过程。由于这些OB相关蛋白的重要性和多重作用，已经对榛子基因组中假定的caleosins对应的序列进行了计算机鉴定，并使用蛋白质组学方法验证了与种子OB的相关性。在榛子基因组中已鉴定出五个属于全长古菌素组（H和L）的全长序列（CavCLO-H1，CavCLO-H2，CavCLO-H3，CavCLO-L1，CavCLO-L2）。鉴定出的钙黄绿素的数量与先前在其他植物物种中观察到的数量一致，这证实钙黄绿素包含植物中的小基因家族。蛋白质组学方法仅允许我们验证榛子OB中CavCLO-H1的存在，这表明该家族中的几个成员在植物生长和发育过程中可能扮演不同的角色。计算机分析还表明，CavCLO-H1可能充当过氧化酶。
