Abstract: Mongolian Almond (Prunus mongolica Maxim)belongs to Rosaceae,under national protection of second class,primarily distributes at the Northwestern Dessert Region of China and is tolerant to drought and poor soil.Calcium ion is the most important signaling molecule for plant sensing and resistance to environment stresses.In this study,based on transcriptome analysis of the leaf,we identified sixteen strings of full length transcripts,including four Ca2+ ATPase (ECA/ACA),three novel Ca2+ channel protein with several transmembrane domains (ERD),five Ca2+/H+ antiporter (CAX),two Ca2+ dependent protein kinase (CPK)and two calmodulins (CAM).Their predicated structures are similar to those homologies in Arabidopsis.Four single genes from the ERD,CAX,CPK and CAM categories,respectively,had obvious expression in the leaves and roots,among which the ERD,CPK and CAM genes expression had been regulated by drought and salt at different extent.It indicated that the genes might modulate the plant's environmental stress-tolerant ability.

Key words: Mongolian almond, Transcriptome, Ca2+ binding protein, Calmodulin
