Molecular identity of ramie germplasms using simple sequence repeat markers
Authors: M.B. Luan, B.F. Chen, Z.Z. Zou, J.J. Zhu, X.F. Wang, Y. Xu,Z.M. Sun and J.H. Chen
DNA identity is highly effective and efficient for distinguishing crop varieties regardless of their phenotypic similarities. To establish DNA identity in ramie, 21 simple sequence repeat primers were amplified in 108 accessions of domestic and exotic ramie germplasms. Sixty polymorphic bands were obtained, with an average of 2.9 bands per locus and 2-8 b.. Read More»

The synthesis of a new cassava-derived species, Manihot vieiri Nassar*
Authors: N.M.A. Nassar
A new species was synthesized artificially by chromosome doubling in a hybrid. The ensuing polyploid type exhibits an apomictic nature and maintains its morphological characteristics in the progeny. It showed a frequency of multiembryonic sacs of 29% in the ovules examined, whereas sacs were absent in the diploid type... Read More»

Drought tolerant stem anatomy characteristics in Manihot esculenta (Euphorbiaceae) and a wild relative
Authors: N.M.A. Nassar, L.F.A. Abreu, D.A.P. Teodoro and D. Graciano-Ribeiro
The stem structure of two cassava cultivars, UnB 99 and UnB 110, known for being adapted to humid conditions and tolerant to drought, respectively, and of a wild species, Manihot glaziovii, was examined anatomically. Free-hand sections of secondary stems were made, clarified with 50% sodium hypochlorite solution, stained with .. Read More»

Genetic studies of â??noble caneâ? for identification and exploitation of genetic markers
Authors: S. Nawaz, F.A. Khan, S. Tabasum, M.Z. Iqbal and A. Saeed
Forty genotypes (clones) of sugarcane, including elite lines, commercial cultivars of Saccharum officinarum and clones of S. barberi were fingerprinted with 50 SSR markers using a PCR-based marker assay. Nei’s genetic distances for SSR data were determined and relationships between accessions were portrayed graphically i.. Read More»

Characterization of the dry bean polygalacturonase-inhibiting protein (PGIP) gene family during Sclerotinia sclerotiorum (Sclerotiniaceae) infection
Authors: M.B. Oliveira1, L.B. Nascimento1, M.L. Junior2 and S. Petrofeza1
Polygalacturonase-inhibiting proteins are leucine-rich repeat proteins that inhibit fungal endopolygalacturonases. The interaction of polygalacturonase-inhibiting protein with endopolygalacturonases limits the destructive potential of endopolygalacturonases and may trigger plant defense responses induced by oligogalacturonides..

Evaluation of insertion-deletion markers suitable for genetic diversity studies and marker-trait correlation analyses in cultivated peanut (Arachis hypogaea L.)
Authors: S. Meng, X.L. Yang, P.M. Dang, S.L. Cui, G.J. Mu, C.Y. Chen and L.F. Liu
Peanut is one of the most important oil crops worldwide. We used insertion-deletion (InDel) markers to assess the genetic diversity and population structure in cultivated peanut. Fifty-four accessions from North China were genotyped using 48 InDel markers. The markers amplified 61 polymorphic loci with 1 to 8 alleles and an average of 2.6 alleles per mark.. Read More»

Cloning and characterization of peanut allene oxide cyclase gene involved in salt-stressed responses
Authors: H.H. Liu, Y.G. Wang, S.P. Wang and H.J. Li
In this study, the full-length cDNA encoding allene oxide cyclase (AhAOC) was isolated from peanut (Arachis hypogaea L.). The deduced amino acid sequence of AhAOC showed high homology with other plant AOCs. The transcript of AhAOC was found to be abundantly expressed in roots. Expression analysis demonstrated that AhAOC was induced by abscisic acid, methy.. Read More»

Estimation of genetic variability among peanut genotypes for resistance to leaf spot disease
Authors: Q. Bano, M. Hassan, S.B. Hussain, M. Javed, M.A. Zulfiqar, M. Younas, M. Baber, M. Zubair and S.M. Hussain
This study aimed to identify high-yielding peanut genotypes with resistance to leaf spot disease. The experimentsincluded material from fourteen local and four exotic peanut genotypes that showed highly significant differences among morphological and disease severity parameters in all the genotypes which, in turn, suggested diversity genotypes. Disease se.. Read More»

Genetic relationships among turnip (Brassica rapa var. rapa) genotypes
Authors: E. Yildirim, N. Yildirim, S. Ercisli, G. Agar and H. Karlidag
Turnip (Brassica rapa var. rapa) is one of the main vegetables consumed by people living in Eastern Anatolia in Turkey. In this region, farmers obtain their own seeds for production, which results in considerable morphological variability. We examined the genetic variation and relationships among 11 turnip genotypes sampled fr.. Read More»

Development of EST-SSR markers in the relict tree Davidia involucrata (Davidiaceae) using transcriptome sequencing
Authors: Z.C. Long, A.W. Gichira, J.M. Chen, Q.F. Wang and K. Liao
Davidia involucrata, reputed to be a “living fossil” in the plant kingdom, is a relict tree endemic to China. Extant natural populations are diminishing due to anthropogenic disturbance. In order to understand its ability to survive in a range of climatic conditions and to design conservation strategies for this en.. Read More»
