In vitro embryo rescue culture of F1 progenies from crosses between different ploidy grapes
Authors: W. Ji, G.R. Li , Y.X. Luo, X.H. Ma, M. Wang and R. Ren
Crossing different ploidy grapes is an effective way to obtain new seedless cultivars. Although embryo rescue has been extensively applied in breeding seedless and triploid grapes, only a few improved cultivars have been developed. Based on preliminary studies, we set five crosses between tetraploid and diploid grape varieties to obtain new hybrid triploi.. Read More»

Genotype x environment interaction and its implication in identification of common bean populations with high calcium content
Authors: S.B. Fernandes, A.F.B. Abreu and M.A.P. Ramalho
The common bean is a food with high mineral content. Of the various types of beans cultivated in Brazil, carioca type beans are the most consumed. The aim of this study was to identify promising common bean populations with an emphasis toward the selection of carioca type bean lines with high calcium content. We also aimed to .. Read More»

Heterosis and correlation in interspecific and intraspecific hybrids of cotton
Authors: S. Munir, S.B. Hussain, H. Manzoor, M.K. Quereshi, M. Zubair,W. Nouman, A.N. Shehzad, S. Rasul and S.A. Manzoor
Interspecific and intraspecific hybrids show varying degrees of heterosis for yield and yield components. Yield-component traits have complex genetic relationships with each other. To determine the relationship of yield-component traits and fiber traits with seed cotton yield, six lines (Bt. CIM-599, CIM-573, MNH-786, CIM-554,.. Read More»

Genetic variation in wild populations of the tuber crop Amorphophallus konjac (Araceae) in central China as revealed by AFLP markers
Authors: C. Pan, A.W. Gichira and J.M. Chen
Amorphophallus konjac is an economically important crop. In order to provide baseline information for sustainable development and conservation of the wild plant resources of A. konjac, we studied the genetic diversity and population structure of this species using amplified fragment length polymorphism (AFLP) molecular markers. We sampled 139 individuals .. Read More»

Transcriptomic analysis of Camellia ptilophylla and identification of genes associated with flavonoid and caffeine biosynthesis
Authors: M.M. Li, J.Y. Xue, Y.L. Wen, H.S. Guo, X.Q. Sun, Y.M. Zhang and Y.Y. Hang
Camellia ptilophylla, or cocoa tea, is naturally decaffeinated and its predominant catechins and purine alkaloids are trans-catechins and theobromine Regular tea [Camellia sinensis (L.) O. Ktze.] is evolutionarily close to cocoa tea and produces cis-catechins and caffeine. Here, the transcriptome of C. ptilophylla was sequenced using the 101-bp paired-end.. Read More»

Isolation and characterization of a chalcone isomerase gene promoter from potato cultivars
Authors: M. Chen, W.J. Zhu, X. You, Y.D. Liu, G.M. Kaleri and Q. Yang
Chalcone isomerase (CHI) is a key enzyme involved in anthocyanin metabolism. Previous research on CHI has mainly focused on cDNA cloning and gene expression. In the current study, the 1425-bp potato CHI promoter (PCP) was isolated from four potato cultivars (Heijingang, Zhongshu 7, Désirée, and Favorita) using PCR and DNA sequencing. The PCP.. Read More»

Identification of genes associated with the increased number of four-seed pods in soybean (Glycine max L.) using transcriptome analysis
Authors: Z.Z. Liu, D. Yao, J. Zhang, Z.L. Li, J. Ma, S.Y. Liu, J. Qu, S.Y. Guan, D.D. Wang, L.D. Pan, D. Wang and P.W. Wang
Seed number per pod is an important component of yield traits in soybean (Glycine max L.). In 2010, we identified a natural mutant with an increased number of four-seed pods from a soybean variety named ‘Jinong 18’ (JN18). Subsequent observations indicated that the trait was stably inherited. To identify and understand the function of genes as.. Read More»

Molecular cloning and expression analysis of heat shock protein 20 (HSP20) from the pearl oyster Pinctada martensii
Authors: Q.N. Lei, Y.Y. Wu, H.Y. Liang, Z.X. Wang, Z. Zheng and Y.W. Deng
Small heat shock proteins (HSPs) are molecular chaperones with ATP-independent properties. They are involved in a variety of physiological and stress processes. In this study, the full-length HSP 20 (HSP20) from Pinctada martensii, designated as PmHSP20, was obtained from hemocytes using rapid amplification of cDNA ends techno.. Read More»

Soybean Stem Fly, Melanagromyza sojae (Diptera: Agromyzidae), in the New World: detection of high genetic diversity from soybean fields in Brazil
Authors: J.A. Arnemann, W.T. Tay, T.K. Walsh H. Brier, K. Gordon,F. Hickmann, G. Ugalde and J.V.C. Guedes
Soybean Stem Fly (SSF), Melanagromyza sojae (Zehntner), belongs to the family Agromyzidae and is highly polyphagous, attacking many plant species of the family Fabaceae, including soybean and other beans. SSF is regarded as one of the most important pests in soybean fields of Asia (e.g., China, India), North East Africa (e.g.,.. Read More»

Enhanced salt tolerance in tomato plants constitutively expressing heat-shock protein in the endoplasmic reticulum
Authors: C. Fu, X.X. Liu, W.W. Yang, C.M. Zhao and J. Liu
The accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER) causes ER stress and activates the unfolded protein response (UPR) signaling pathway. The UPR signaling pathway is associated with plant responses to adverse environmental conditions. Thus, changes in the UPR signaling pathway might affect pla.. Read More»
