Breeding new seedless grape by means of in vitro embryo rescue
Authors: W. Ji, Z.-Q. Li, Q. Zhou, W.-K. Yao and Y.-J. Wang
This project aimed at breeding new seedless grape cultivars by embryo rescue through three hybridization methods: 1) using cross-breeding between seedless Vitis vinifera cultivars and wild Chinese Vitis spp; 2) crossing with two seedless cultivars, and 3) hybridization between grapes of different ploidy. Genotype, sampling times, and media were confirmed .. Read More»

Microsporogenesis in Brachiaria dictyoneura (Fig. & De Not.) Stapf (Poaceae: Paniceae)
Authors: C. Risso-Pascotto, M.S. Pagliarini and C.B. Valle
Microsporogenesis was analyzed in five accessions of Brachiaria dictyoneura presenting x = 6 as the basic chromosome number. All accessions were tetraploid (2n = 4x = 24) with chromosome pairing in bi-, tri-, and quadrivalents. The recorded meiotic abnormalities were those typical of polyploids, including precocious chromosome.. Read More»

Evidence of allopolyploidy in Brachiaria brizantha (Poaceae: Paniceae) through chromosome arrangement at metaphase plate during microsporogenesis
Authors: C. Risso-Pascotto, D.V. Mendes, N. Silva, M.S. Pagliarini and C.B. Valle
In the hexaploid (2n = 6x = 54) accession B176 of Brachiaria brizantha, one cytological characteristic differentiated it from the other accessions previously analyzed with the same ploidy level. Nearly 40% of meiocytes displayed the chromosome set arranged at two metaphase plates at the poles of the cell, close to the membrane.. Read More»

Clustering of soybean genotypes via Ward-MLM and ANNs associated with mixed models
Authors: P.E. Teodoro, F.E. Torres and A.M. Corr�?ªa
The objectives of this study were to use mixed models to confirm the presence of genetic variability in 16 soybean genotypes, to compare clusters generated by artificial neural networks (ANNs) with those created by the Ward modified location model (MLM) technique, and to indicate parental combinations that hold promise for obtaining superior segregating p..

Effects of using phenotypic means and genotypic values in GGE biplot analyses on genotype by environment studies on tropical maize (Zea mays)
Authors: I.S.C. Granato, R. Fritsche-Neto, M.D.V. Resende and F.F. Silva
The objective of this study was to examine the effects of the type and intensity of nutritional stress, and of the statistical treatment of the data, on the genotype x environment (G x E) interaction for tropical maize (Zea mays). For this purpose, 39 hybrid combinations were evaluated under low- and high-nitrogen and -phospho.. Read More»

Expressed sequenced tags from Lygus lineolaris (Hemiptera: Miridae), the tarnished plant bug
Authors: Allen ML
Expressed sequenced tags (ESTs) were prepared to establish a baseline for molecular genetic studies of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois). The largest class of identifiable ESTs (15.2%) was from genes involved in cellular metabolic functions, including physiological processes. Twenty-seven ESTs (9... Read More»

Expression profile analysis of ascorbic acid-related genes in response to temperature stress in the tea plant, Camellia sinensis (L.) O. Kuntze
Authors: H. Li, W. Huang, G.L. Wang, Z.J. Wu and J. Zhuang, Tea Scienc
Ascorbic acid (AsA), also known as ascorbate or vitamin C, is a natural organic compound in green plants that has antioxidant properties, and is an essential nutrient for humans. The tea plant, Camellia sinensis (L.) O. Kuntze, is an important global economic crop. Here, the expression profiles of genes related to AsA biosynth.. Read More»

Isolation and characterization of microsatellite markers for Dendranthema morifolium (Asteraceae) using next-generation sequencing
Authors: W.J. Yuan, S. Ye, L.-H. Du, S.-M. Li, X. Miao and F.-D. Shang
Dendranthema morifolium (Asteraceae) is a perennial herbaceous plant native to China. A long history of artificial crossings may have resulted in complex genetic background and decreased genetic diversity. To protect the genetic diversity of D. morifolium and enabling breeding of new D. morifolium cultivars, we developed a set.. Read More»
