Low temperature is one of the major factors limiting pepper (Capsicum annuum L.) production during winter and early spring in non-tropical regions. Application of exogenous abscisic acid (ABA) effectively alleviates the symptoms of chilling injury, such as wilting and formation of necrotic lesions on pepper leaves; however, the underlying molecular(More)
The F-box protein family is characterized by an F-box motif that has been shown to play an important role in regulating various developmental processes and stress responses. In this study, a novel F-box-containing gene was isolated from leaves of pepper cultivar P70 (Capsicum annuum L.) and designated CaF-box. The full-length cDNA is 2088 bp and contains an(More)
The most significant threat to pepper production worldwide is the Phytophthora blight, which is caused by the oomycete pathogen, Phytophthora capsici Leonian. In an effort to help control this disease, we isolated and characterized a P. capsici resistance gene, CaRGA2, from a high resistant pepper (C. annuum CM334) and analyzed its function by the method of(More)
Cysteine proteinases have been known to participate in developmental processes and in response to stress in plants. Our present research reported that a novel CP gene, CaCP, was involved in leaf senescence in pepper (Capsicum annuum L.). The full-length CaCP cDNA is comprised of 1316 bp, contains 1044 nucleotides in open reading frame (ORF), and encodes a(More)
Ubiquitous cell membrane proteins called aquaporins are members of major intrinsic proteins (MIPs), which control the specific transport of water molecules across cell membranes. A pepper aquaporin gene (CaAQP), which exhibits the structural features of tonoplast intrinsic proteins of the MIP subfamily, was isolated from the leaves of chilling-treated(More)
Molecular markers, coxII SCAR, atp6-2 SCAR and accD-U, have been used for marker-assisted selection of cytoplasmic male sterility (CMS) in pepper. However, the presence of these markers at the sub-stoichiometric level in maintainer lines affects the reliable selection of male sterile (S-) cytoplasm. This study aimed to develop a new CMS-specific molecular(More)
Pollen formation is a complex process that is strictly controlled by genetic factors. Although many novel mitochondrial genes have been implicated in the dysfunction of mitochondrial enzymes and the cytoplasmic male sterility (CMS), there is little empirical evidence to show that CMS-related genes actually result in the dysfunction of enzyme and little is(More)
The pepper fruit is the second most consumed vegetable worldwide. However, low temperature affects the vegetative development and reproduction of the pepper, resulting in economic losses. To identify cold-related genes regulated by abscisic acid (ABA) in pepper seedlings, cDNA representational difference analysis was previously performed using a suppression(More)
Though cytoplasmic male sterility (CMS) in peppers is associated with the orf507 gene, definitive and direct evidence that it directly causes male sterility is still lacking. In this study, differences in histochemical localization of anther cytochrome c oxidase between the pepper CMS line and maintainer line were observed mainly in the tapetal cells and(More)
The plant-specific NAC (NAM, ATAF, and CUC) transcription factors have diverse role in development and stress regulation. A new transcript encoding NAC protein, homologous to nam-like protein 4 from Petunia was identified from an ABA-regulated subtractive cDNA library of Capsicum annuum seedling. Here, this homolog (named CaNAC2) from C. annuum was(More)
