Inter- and intra-specific genetic diversity of Iranian yarrow species Achillea santolina and Achillea tenuifolia based on ISSR and RAPD markers
Authors: M. Ebrahimi M. Farajpour M. Rahimmalek
Cultivation and preservation of yarrow has recently attracted wide attention due to its beneficial properties; however, genetic variation of Achillea species is still relatively unknown. We used RAPD and ISSR markers to assess genetic diversity in 16 accessions of yarrow belonging to two species native to Iran. Seven ISSR and nine RAPD primers generated 1.. Read More»

Molecular characterization of wheat germplasm using microsatellite markers
Authors: S. Ijaz and I.A. Khan
We investigated the genetic diversity of 63 wheat genotypes, composed of 48 accessions and 15 varieties, using 56 polymorphic simple sequence repeat primers. One hundred and eighty-six loci were found, with a mean of 131.26 alleles per locus. Cluster analysis based on microsatellite allelic diversity discriminated the accessions and varieties into di..

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»

Diversity and genetic stability in banana genotypes in a breeding program using inter simple sequence repeats (ISSR) markers
Authors: A.V.C. Silva, A.L.S. Nascimento, M.F. Vit�³ria, A.R.C. Rabbani, A.N.R. Soares and A.S. L�©do
Banana (Musa spp) is a fruit species frequently cultivated and consumed worldwide. Molecular markers are important for estimating genetic diversity in germplasm and between genotypes in breeding programs. The objective of this study was to analyze the genetic diversity of 21 banana genotypes (FHIA 23, PA42-44, Maç&atild.. Read More»

Single nucleotide polymorphisms from Theobroma cacao expressed sequence tags associated with witches� broom disease in cacao
Authors: L.S. Lima1, K.P. Gramacho1, N. Carels2, R. Novais1, F.A. Gaiotto2,U.V. Lopes1, A.S. Gesteira2, H.A. Zaidan1,2, J.C.M. Cascardo2,J.L. Pires1 and F. Micheli2,3
In order to increase the efficiency of cacao tree resistance to witches’ broom disease, which is caused by Moniliophthora perniciosa (Tricholomataceae), we looked for molecular markers that could help in the selection of resistant cacao genotypes. Among the different markers useful for developing marker-assisted selection, single nucleotide polymorp.. Read More»

Selecting black-spot resistant papaya genotypes derived from backcrossing and hybrids
Authors: T.P.S. Poltronieri, S.F. Silveira, M. Vivas, R. Santa Catarina,D.F.M. Cortes, A.O.N. Azevedo and M.G. Pereira
Papaya crop is important to Brazilian agribusiness. However, the expansion of papaya cultivation in the country is affected by the absence of commercial cultivars presenting good disease resistance. The black-spot caused by the fungus Asperisporium caricae is the most damaging foliar disease affecting Brazilian papaya crops. T.. Read More»

Variation in genotypic responses and biochemical analysis of callus induction in cultivated wheat
Authors: M.M. Shah1, Q. Khalid1, U.W. Khan1, S.A.H. Shah3, S.H. Shah2,A. Hassan1 and A. Pervez1
Wheat is notorious for callus induction, which is a major hindrance in direct gene transfer and consequently for genetic improvement programs. In order to provide a successful platform for gene transformation, good callus quantity and quality is important. We investigated the variation in callus induction capabilities of Pakistani wheat cultivars and.. Read More»

Expression of metallothionein type 2 and 3 genes in Prosopis glandulosa leaves treated with copper
Authors: C. Michel-Lopez, O. Zapata-P�©rez, D. Gonz�¡lez-Mendoza,O. Grimaldo-Juarez, C. Cece�±a-Duran, O. Tzintzun-Camacho
For a better understanding of the strategies that are used by Prosopis glandulosa in heavy metal tolerance, the present study evaluated the gene expression of three metallothioneins (MTs; PgMt2-1, PgMt2, and PgMt3) in plants exposed to sub-lethal concentrations of copper. The PgMt2-1, PgMt2, and PgMt3 sequences were homologous.. Read More»

Multivariate statistics applied to the reaction of common bean plants to parasitism by Meloidogyne javanica
Authors: L.N.S. Santos, P.D.S. Cabral, G.A.R. Neves, F.R. Alves, M.B. Teixeira1, F.N. Cunha1 N.F. Silva
The availability of common bean cultivars tolerant to Meloidogyne javanica is limited in Brazil. Thus, the present study aimed to evaluate the reactions of 33 common bean genotypes (23 landrace, 8 commercial, 1 susceptible standard and 1 resistant standard) to M. javanica, employing multivariate statistics to discriminate the ..
