Authors: DLD de Melo, AAP Correa, ER Moresco, FM da Silva, BHP Val, AO Di Mauro and SH Uneda-Trevisoli
The aim of this study was to analyze the effects of high temperatures on ear fertility, yield components and protein content of wheat cultivars. Therefore, 96 genotypes were subjected to two environments in a greenhouse: control and heat stress. Each environment had two replicates, totalling 192 plots. The evaluations were: nu.. Read More»

Authors: P.I. Chapla, E.S.N. Vieira, F.A. Franco, G.A. Linde, G.J. Silva, N.B. Colauto, V.S. Marchioro and I. Schuster
Industrial wheat quality flour is related to gluten amount in grain. This study aimed to evaluate the relationship between high molecular weight (HMW) glutenins obtained by SDS-PAGE and gluten strength (W) obtained by the alveograph test and cropping environmental effect on wheat flour quality for Brazilian industry. Fifty-one.. Read More»

Comparison of small scale methods for the rapid and efficient extraction of mitochondrial DNA from wheat crop suitable for down stream processes
Authors: M. Ejaz*, Z. Qidi*, Z. Gaisheng, W. Qunzhu, N. Na and Z. Huiyan
We evaluated and compared 2 mitochondrial DNA (mtDNA) extraction methods in terms of DNA quality and success of subsequent polymerase chain reaction (PCR) amplifications from etiolated leaves of wheat crop (Triticum aestivum). mtDNA extraction is difficult because the presence of metabolites interfere with DNA isolation procedures and downstream applicati..

Impact of forage clipping treatments on performance of winter wheat
Authors: S.A. Jadoon1, H. Ullah1, F. Mohammad2, I.H. Khalil2, M. Alam1,D. Shahwar1, M.F.A. Malik1 and Y. Jamal1
Farmers in northern parts of Pakistan face severe shortage of green forage for their livestock during the harsh winter season. Winter wheat has the potential to be used as a dual-purpose crop for forage plus grain production in these areas. Ten elite winter wheat lines from Oklahoma State University were evaluated at Hazara Research Station Abbottabad und.. Read More»

Diversity resistance to Puccinia striiformis f. sp Tritici in rye chromosome arm 1RS expressed in wheat
Authors: M.Y. Yang, T.H. Ren, B.J. Yan, Z. Li and Z.L. Ren
The 1BL.1RS wheat-rye translocation contained in the Russian cultivar Aurora has been the most widespread alien translocation in wheat-breeding programs all over the world. However, following the prevalence of new biotypes of the pathogens, disease-resistance genes in this translocation chromosome have been overcome and consequently they have been elimina.. Read More»

Cytogenetic and molecular identification of a wheat-Leymus mollis alien multiple substitution line from octoploid Tritileymus x Triticum durum
Authors: Y.H. Pang, J.X. Zhao, W.L. Du, Y.L. Li, J. Wang, L.M. Wang, J. Wu, X.N. Cheng, Q.H. Yang and X.H. Chen
Leymus mollis (Trin.) Pilger (NsNsXmXm, 2n = 28), a wild relative of common wheat, possesses many traits that are potentially valuable for wheat improvement. In order to exploit and utilize the useful genes of L. mollis, we developed a multiple alien substitution line, 10DM50, from the progenies of octoploid Tritileymus M842-1.. Read More»

Identification of the isoamylase 3 gene in common wheat and its expression profile during the grain-filling period
Authors: G.Z. Kang, G.Q. Liu, W. Xu, Y.J. Zhu, C.Y. Wang, H.Q. Ling and T.C. Guo
In higher plants, isoamylase-type starch debranching enzyme catalyzes the α-1,6-glucosidic linkages of glycogen and phytoglycogen. We cloned an isoamylase-type starch debranching enzyme ISA3 cDNA sequence (2883 bp), designated as TaISA3, from common wheat (Triticum aestivum), using the rapid amplification of cDNA ends method. The open reading frame .. Read More»

Molecular cloning and characterization of a proliferating cell nuclear antigen gene by chemically induced male sterility in wheat (Triticum aestivum L.)
Authors: Y.A. Yu, G.S. Zhang, J. Zhang, L. Ju, Q.D. Zhu, Y.L. Song, J.W. Wang, N. Niu and S.C. Ma
Although a number of studies have shown that chemical hybridizing agents (CHAs) affect anther growth and regulate cell-cycle progression, little is known about the molecular and cellular mechanisms involved. Proliferating cell nuclear antigen (PCNA) is an essential factor in DNA replication, and in many other processes in euka.. Read More»

Authors: M. Lu*, L. Wang*, J. Zhang, S. Sun, Y. Li, W. Du, J. Wu, J. Zhao, Q. Yang and X. Chen
A wheat germplasm line 13-2-2 with resistance to powdery mildew was isolated; this line was derived from common wheat cv. W770B and rye, Secale cereale L. (2n = 2x = 14, RR). The line was characterized based on cytological, genomic in situ hybridization (GISH), sequence-characterized amplified region (SCAR), and simple sequence repeat (SSR) analyses. The .. Read More»
