摘要： Ca2+-ATPases have been confirmed to play very important roles in plant growth and development and in stress responses. However, studies on banana (Musa acuminata) Ca2+-ATPases are very limited. In this study, we identified 18 Ca2+-ATPase genes from banana, including 6 P-IIA or ER (Endoplasmic Reticulum) type Ca2+-ATPases (MaEACs) and 12 P-IIB or Auto-Inhibited Ca2+-ATPases (MaACAs). The MaEACs and MaACAs could be further classified into two and three subfamilies, respectively. This classification is well supported by their gene structures, which are encoded by protein motif distributions. The banana Ca2+-ATPases were all predicted to be plasma membrane-located. The promoter regions of banana Ca2+-ATPases contain many cis-acting elements and transcription factor binding sites (TFBS). A gene expression analysis showed that banana Ca2+-ATPases were differentially expressed in different organs. By investigating their expression patterns in banana roots under different concentrations of Ca2+ treatments, we found that most banana Ca2+-ATPase members were highly expressed under 4 mM and 2 mM Ca2+ treatments, but their expression decreased under 1 mM and 0 mM Ca2+ treatments, suggesting that their downregulation might be closely related to reduced Ca accumulation and retarded growth under low Ca2+ and Ca2+ deficiency conditions. Our study will contribute to the understanding of the roles of Ca2+-ATPases in banana growth and Ca management.
