摘要: Plant aquaporins are responsible for water transmembrane transport, which play an important role on abiotic and biotic stresses. A novel plasma membrane intrinsic protein of CaPIP1-1 was isolated from the pepper P70 according to transcriptome databases of Phytophthora capsici inoculation and chilling stress library. CaPIP1-1, which is 1155 bp in length with an open reading frame of 861 bp, encoded 286 amino acids. Three introns, exhibited CT/AC splice junctions, were observed in CaPIP1-1. The numbers and location of introns in CaPIP1-1 were the same as observed in tomato and potato. CaPIP1-1 was abundantly expressed in pepper fruit. Increased transcription levels of CaPIP1-1 were found in the different stresses, including chilling stress, salt stress, mannitol stress, salicylic acid, ABA treatment and Phytophthora capsici infection. The expression of CaPIP1-1 was downregulated by 50 mu M HgCl and 100 mu M fluridone. The pepper plants silenced CaPIP1-1 in cv. Qiemen showed growth inhibition and decreased tolerance to salt and mannitol stresses using detached leaf method. (C) 2015 Elsevier B.V. All rights reserved.
