Genetic divergence for high-molecular weight glutenin subunits (HMW-GS) in indigenous landraces and commercial cultivars of bread wheat of Pakistan
Authors: F. Yasmeen, H. Khurshid and A. Ghafoor
Wheat flour quality is an important consideration in the breeding and development of new cultivars. A strong association between high-molecular weight glutenin subunits (HMW-GS) and bread making quality has resulted in the widespread utilization of HMW-GS in wheat breeding. In this study, we analyzed 242 lines of wheat, including landraces from the provin.. Read More»

Gender identification of five genera of stingless bees (Apidae, Meliponini) based on wing morphology
Authors: T.M. Francoy R.A.O. Silva P. Nunes-Silva C. Menezes V.L. Imperatriz-Fonseca
Currently, the identification of pollinators is a critical necessity of conservation programs. After it was found that features extracted from patterns of wing venation are sufficient to discriminate among insect species, various studies have focused on this structure. We examined wing venation patterns of males and workers of.. Read More»

Reference genes for quantitative real-time polymerase chain reaction studies in soybean plants under hypoxic conditions
Authors: T.J. Nakayama, F.A. Rodrigues, N. Neumaier, F.C. Marcelino-Guimar�£es, J.R.B. Farias, M.C.N. de Oliveira, A. Bor�©m, A.C.B. de Oliveira, B.M. Emygdio and A.L. Nepomuceno
Quantitative real-time polymerase chain reaction (RT-qPCR) is a powerful tool used to measure gene expression. However, because of its high sensitivity, the method is strongly influenced by the quality and concentration of the template cDNA and by the amplification efficiency. Relative quantifi cation is an effective strategy .. Read More»

Implications of the progeny x environment interaction in selection index involving characteristics of the common bean
Authors: L.K. Lima M.A.P. Ramalho A.F.B. Abreu
Breeders normally select simultaneously for several traits in various environments. We investigated the effects of the progeny x environment interaction on success in selection for several traits. The population used was obtained from a cross between the CVIII-85-11 line, which has a semi-erect to prostrate plant architecture and a cream with brown streak.. Read More»

Development and characterization of genic-SSR markers from different Asia lotus (Nelumbo nucifera) types by RNA-seq
Authors: X.F. Zheng, Y.N. You, Y. Diao, X.W. Zheng, K.Q. Xie, M.Q. Zhou, Z.L. Hu and Y.W. Wang
Nelumbo nucifera is an important economic vegetable and traditional medicine, but available genetic resources remain limited. Next generation sequencing has proven to be a rapid and effective means of identifying genic simple sequence repeat (genic-SSR) markers. This study developed genic-SSRs for N. nucifera using Illumina sequencing technology to assess.. Read More»

QTL verification of grain protein content and its correlation with oil content by using connected RIL populations of high-oil maize
Authors: G.H. Yang, Y.B. Dong, Y.L. Li, Q.L. Wang, Q.L. Shi and Q. Zhou
Maize with high grain protein and oil contents offers great advantages for human food and animal feed. In this study, grain protein contents of 282 and 263 F7:8 recombinant inbred lines (RILs) of 2 crosses were evaluated in 4 environments within and between populations. The RILs were developed from crosses between an inbred hi.. Read More»

Evaluation of genetic dissimilarity in a segregating wine grape population
Authors: A.P. Viana, S. Riaz and M.A. Walker
This study examined the genetic diversity present in a population obtained by crossing two very distinctive varieties of wine grapes (142 progeny from a Riesling x Cabernet Sauvignon cross, including both parents, created at the University of California). The following list of morphological characters were evaluated and found .. Read More»

Ascorbate peroxidase from Jatropha curcas enhances salt tolerance in transgenic Arabidopsis
Authors: Y. Chen, J. Cai, F.X.Yang, B. Zhou and L.R. Zhou
Ascorbate peroxidase (APX) plays a central role in the ascorbate-glutathione cycle and is a key enzyme in cellular H2 O2 metabolism. It includes a family of isoenzymes with different characteristics, which are identified in many higher plants. In the present study, we isolated the APX gene from Jatropha curcas L, which is similar with other previously ch.. Read More»

The pollen wall and tapetum are altered in the cytoplasmic male sterile line RC7 of Chinese cabbage (Brassica campestris ssp pekinensis)
Authors: H.-F. Zhao W. Huang S.S. Ahmed Z.-H. Gong L.-M. Zhao
Cytoplasmic male sterile line RC7 of Chinese cabbage produces mature anthers without pollen. To understand the mechanisms involved, we examined the ultrastructural changes during development of the microspores. Development of microspores was not affected at the early tetrad stage. During the ring-vacuolated period, some large vacuoles appeared in the tape.. Read More»

Molecular authentication of the medicinal herb Ruta graveolens (Rutaceae) and an adulterant using nuclear and chloroplast DNA markers
Authors: F. Al-Qurainy, S. Khan, M. Tarroum, F.M. Al-Hemaid and M.A. Ali
Dried parts of different plant species often look alike, especially in powdered form, making them very difficult to identify. Ruta graveolens, sold as a dried medicinal herb, can be adulterated with Euphorbia dracunculoides. The genomic DNA was isolated from the leaf powder (100 mg each) using the modified CTAB method.
