Identification of low-molecular-weight-glutenin genes from the D-genome of Triticum aestivum, Aegilops crassa, Ae. cylindrica and Ae. tauschii

In this study, in the first experiment, 110 samples of bread wheat, Aegilopscrassa, Ae. cylindrica and Ae. tauschii were investigated to identify low-molecular-weight glutenin subunits. Overall, the four alleles in term of the analysis of SDS-PAGE gels were detected. The ʻaʼ allele with 45% has the greatest frequency, and after that, ʻbʼ, ʻcʼ and ʻdʼ alleles were with 38.1%, 11.8% and 9.1% frequencies, respectively; however, in Ae. crassa, ʻbʼ and ʻcʼ alleles are the highest and lowest frequencies, respectively. Furthermore, the average genetic diversity (H) for the total population was obtained 0.62. In second experiment, twenty low-molecular-weight-glutenin subunit (LMW-GS) gene sequences from the D-genome from Aegilopscrassa (2n=4x=28), Ae. cylindrica (2n=4x=28), Ae. tauschii (2n=2x=14) and T. aestivum (2n=6x=42) were obtained using five sets of specific allele primer pairs. Based on DNA and predicted protein sequences, phylogenetic trees for all sets of sequences were drawn. At the DNA level, the species closest to T. aestivum for the second, third, fourth and fifth set of sequences were Ae. cylindrica, Ae. tauschii, Ae. tauschii and Ae. crassa, respectively. At the protein level, the species closest to T. aestivum based on the first, second and fifth set of sequences were Ae. cylindrica, Ae. crassa and Ae. crassa, respectively. For other sets of sequences, bread wheat proved to be a distinct species. The results show that wild wheat relatives have various alleles that can be utilized them in breeding programs to improve glutenin.


Mohammad Reza Naghavi joined the College of the Agricultural & Natural Resources, University of Tehran (UT) in 2000 as an Assistant Professor and was promoted to Associate Professor in 2004 and Professor in 2008. He served as the Director of the Science and Engineering Faculty from 2011 to 2013 and has served as the Dean of Science and Technology of the Agricultural & Natural Resources College at UT since 2014. 

He has received almost every top award including National, University and College Merit Credit Awards for Innovative Teaching and Research Activities (2000, 2001, 2009, 2013 and 2014). He also received some awards for presentation and participation in National and International conferences (2009, 2010, 2013 and 2014). In 2014, he received a grant from European Commission mobility program at the University of Warsaw. In addition, he was elected as one of the top researchers at the University of Tehran in 2014. 

His main research interests include plant diversity, metabolic engineering in plant and population genetics. He has received more than eight research grants from industry, foundations, and state and he has used such funding to support research of many undergraduate students. More than 40 undergraduate students have participated in his researches. In order to conserve plant germplasm, he has collected some usefulgermplasm from different part of Iran. To give his work the maximum possible impact and application, he has collaborated with a wide range of professionals involved in the issues he study. He has given more than 15 research presentations in several different countries, 5 of which were “Invited Talks”. In addition, more than 20 of his undergraduate students in the past have made oral presentations at regional, national, and international conferences.
