QTL Mapping for Dough Mixing Characteristics in a Recombinant Inbred Population Derived from a Waxy×Strong Gluten Wheat (Triticum aestivum L.)

Journal of Integrative Agriculture 2013年第6期12卷 951-961页

作者： ZHENG Fei-fei DENG Zhi-ying SHI Cui-lan ZHANG Xin-ye tian Ji-chun State Key Laboratory of Crop Biology Ministry of Science and Technology/Key Labo rator y of Crop Biolog y of Shand ong Provin ce Education Department of Shandong Province/Agronomy College Shandong Agricultural University

Protein and starch are the most important traits in determining processing quality in wheat. In order to understand the genetic basis of the influence of Waxy protein （Wx） and high molecular weight gluten subunit （HMW-GS） on processing quality, 256 recombinant inbred lines （RILs） derived from the cross of waxy wheat Nuomai 1 and Gaocheng 8901 were used as mapping population. DArT （diversity arrays technology）, SSR （simple sequence repeat）, HMW-GS, and Wx markers were used to construct the molecular genetic linkage map. QTLs for mixing peak time （MPT）, mixing peak value （MPV）, mixing peak width （MPW）, and mixing peak integral （MPI） of Mixograph parameters were evaluated in three different environments. The genetic map comprised 498 markers, including 479 DArT, 14 SSR, 2 HMW-GS, and 3 Wx protein markers, covering 4 229.7 cM with an average distance of 9.77 cM. These markers were identified on 21 chromosomes. Eighteen additive QTLs were detected in three different environments, which were distributed on chromosomes 1A, 1B, 1D, 4A, 6A, and 7D. QMPT-1D.1 and QMPT-1D.2 were close to the Glu-D1 marker accounting for 35.2, 22.22 and 36.57% of the phenotypic variance in three environments, respectively. QMPV-1D and QMPV-4A were detected in all environments, and QMPV-4A was the nearest to Wx-B1. One minor QTL, QMPI-1A, was detected under three environments with the genetic distances of 0.9 cM from the nearest marker Glu-A1, explaining from 5.31 to 6.67% of the phenotypic variance. Three pairs of epistatic QTLs were identified on chromosomes 2D and 4A. Therefore, this genetic map is very important and useful for quality trait related QTL mapping in wheat. In addition, the finding of several major QTLs, based on the genetic analyses, further suggested the importance of Glu-1 loci on dough mixing characteristics.

Penile rehabilitation with a vacuum erectile device in an animal model is related to an antihypoxic mechanism： blood gas evidence

引用

Asian Journal of Andrology 2013年第3期15卷 387-390页

作者： Hao-Cheng Lin Wen-Li Yang Jun-lan Zhang Yu-tian Dai Run Wang Department of Urology Affiliated Drum Tower Hospital School of Medicine Nanjing University Nanjing 210008 China Division of Urology University of Texas Medical Schoo at Houston TX 77030 USA Division of Gastroenterology Hepatology & Nutrition Department of Internal Medicine University of Texas Medical School at Houston TX 77030 USA Department of Urology University of Texas MD Anderson Cancer Center Houston TX 77030 USA

Our previous study showed that vacuum erectile device （VED） therapy has improved erectile function in rats with bilateral cavernous nerve crush （BCNC） injuries. This study was designed to explore the mechanism of VED in penile rehabilitation by analyzing cavernous oxygen saturation （SO2） and to examine the effect of VED therapy on preventing penile shrinkage after BCNC. Thirty adult Sprague- Dawley rats were randomly assigned into three groups： group 1, sham surgery; group 2, BCNC; and group 3, BCNC＋VED. Penile length and diameter were measured on a weekly basis. After 4 weeks of therapy, the penile blood was extracted by three methods for blood gas analysis （BGA）： method 1, cavernous blood was aspirated at the flaccid state; method 2, cavernous blood was aspirated at the traction state; and method 3, cavernous blood was aspirated immediately after applying VED. SO2 values were tested by the blood gas analyzer. The results showed that VED therapy is effective in preventing penile shrinkage induced by BCNC （Penile shortening： BCNC group 1.9±1.1 mm; VED group 0.3±1.0 mm; P〈0.01. Penile diameter reduction： BCNC group 0.28±0.14 mm; VED group 0.04±0.14 mm; P〈0.01）. The mean SO2±s.d. values were increased by VED application （88.25%±4.94%） compared to the flaccid （76.53%±4.16%） or traction groups （78.93%±2.56%）（P〈0.05）. The calculated blood constructs in the corpus cavernosum right after VED application were 62% arterial and 38% venous blood. These findings suggest that VED therapy can effectively preserve penile size in rats with BCNC injury. The beneficial effect of VED therapy is related to antihypoxia by increasing cavernous blood SO2.
