Capsicum
Estimate of natural cross-pollination rate of Capsicum annuum using a codominant molecular marker associated with fruit pungency
Authors: EV Justino, MEN Fonseca, ME Ferreira, LS Boiteux, PP Silva, WM Nascimento
The production of seeds with high genetic quality requires accurate estimates of the natural cross-pollination rate in cultivated Capsicum species. This is important in order to establish the most suitable isolation distance among fields of distinct genotypes, to minimize the risk of genetic contamination and to ensure that th.. Read More»

Genetic effects of in vitro germination and plantlet development in chilli pepper
Authors: P.A. Barroso, M.M. R�ªgo, E.R. R�ªgo and K.T.C. Ferreira
The objective of this study was to estimate the genetic effects on in vitro germination and development of chili peppers. For this, four genotypes (UFPB-132, -134, -137, and -390) were used as parents. They were crossed in a complete diallel scheme. The parents (4) and hybrid (12) seeds were germinated in glass bottles contain.. Read More»

Molecular characteristics and cloning of two pepper genes AN2 and UPA20
Authors: H.X. Chen, H. Jiang, J.L. Huo, J.F. Wen, H.S. Zhu, C.H. Ma, H. Zhou, J.H. Lv and M.H. Deng
The complete coding sequences (CDSs) of “Yunnan Purple Pepper No.1” (Capsicum annuum L.) AN2 and UPA20 genes were amplified using the reverse transcriptase polymerase chain reaction on the basis of the conserved sequence information of some Solanaceae plants and known highly homologous pepper expressed sequence tags. The nucleotide sequence an.. Read More»

Characterizing and marker-assisting a novel chili pepper (Capsicum annuum L.) yellow bud mutant with cytoplasmic male sterility
Authors: G.S. Sun, Z.L. Dai, P.W. Bosland, Q. Wang, C.Q. Sun, Z.C. Zhang and Z.H. Ma
Cytoplasmic male sterility (CMS) in pepper is a better way to produce hybrid seeds compared to manual production. We used the two sequence characterized amplified region (SCAR) markers (CRF-SCAR and CMS-SCAR130) in CMS pepper, to identify the genotype. We assembled two CMS yellow bud mutants (YBM; YBM12-A and YBM12-B). This mu.. Read More»

Molecular cloning, sequence characterization of a novel pepper gene NADP-ICDH and its effect on cytoplasmic male sterility
Authors: M.H. Deng J.F. Wen J.L. Huo H.S. Zhu X.Z. Dai Z.Q. Zhang H. Zhou X.X. Zou
NADP-dependent isocitrate dehydrogenase (NADP-ICDH) is an important enzyme involved in energy metabolism. The complete coding sequence of the pepper (Capsicum annuum) NADP-ICDH gene was amplified using a reverse transcriptase PCR based on the conserved sequence information of the tomato and other Solanaceae plants and known highly homologous pepper ESTs. Nuc.. Read More»

Cloning and expression analysis of pepper chlorophyll catabolite reductase gene CaRCCR
Authors: H.-J. Xiao, J.-H. Jin, W.-G. Chai and Z.-H. Gong
Opening the porphyrin macrocycle of pheophorbide a and forming the primary fluorescent chlorophyll catabolites are key steps in the chlorophyll catabolism pathway. These steps are catalyzed by pheophorbide a oxygenase and red chlorophyll catabolite reductase (RCCR). In this study, a novel RCCR gene, CaRCCR, was isolated from the pepper (Capsicum annuum L...

Genotype x environment interaction on experimental hybrids of chili pepper
Authors: N.S.S. Cabral, A.M. Medeiros, L.G. Neves, C.P. Sudr�©, S. Pimenta, V.J. Coelho, M.E. Serafim and R. Rodrigues
In Brazil, cultivation of hybrid plants comprise near 40% of the area grown with vegetables. For Capsicum, hybrids of bell and chili peppers have already exceeded 50% and over 25% of all are commercialized seeds. This study aimed to evaluate new pepper hybrids in two environments, Cáceres, MT, and Campos dos Goytacazes,.. Read More»

Novel and highly informative Capsicum SSR markers and their cross-species transferability
Authors: G.S.C. Buso, A.M.M. Reis, Z.P.S. Amaral and M.E. Ferreira
This study was undertaken primarily to develop new simple sequence repeat (SSR) markers for Capsicum. As part of this project aimed at broadening the use of molecular tools in Capsicum breeding, two genomic libraries enriched for AG/TC repeat sequences were constructed for Capsicum annuum. A total of 475 DNA clones were sequenced from both libraries and 1.. Read More»

We estimated the genetic diversity of 49 accessions of the hot pepper species Capsicum chinensis through analyses of 12 physicochemical traits of the fruit, eight multi-categorical variables, and with 32 RAPD primers. Data from the physicochemical traits were submitted to analysis of variance to estimate the genetic parameters.. Read More»

Cloning and bioinformatic analysis of full-length novel pepper (Capsicum annuum) genes TAF10 and TAF13
Authors: J.F. Wen, J.L. Huo, H.X. Chen, C.H. Ma, H. Jiang, H.S. Zhu, H. Zhou and M.H. Deng
We isolated two TATA-binding protein-associated factor (TAF) genes, TAF10 and TAF13, from pepper (Capsicum annuum). The complete coding sequences were amplified using reverse transcriptase-PCR on the basis of conserved sequence information of eggplant and several other plant species. Nucleotide sequence analysis of these two genes revealed that the pepper.. Read More»
