Isoflavones are a class of compounds present in high amounts in soybean seeds, which can be used for prevention and treatment
of several chronic diseases. Proteins present in soybean seeds are the basis for the high nutritional value and versatility
of this leguminous species in animal and human feeding. The main goals of this work were to estimate heritabilities for isoflavone
contents in soybean seeds and the correlation between isoflavone and protein contents. Commercial variety IAC-100 (high isoflavone
and normal protein contents) and the line BARC-8 (low isoflavone and high protein contents) were crossed, and one single F1 plant derived 97 F2 seeds, which were used to obtain F3 seeds. A sample of F3 seeds from each F2 plant was used for isoflavone determination by HPLC and protein by the Kjeldahl method. Six isoflavone forms were detected:
daidzin, genistin, glycitin, malonyldaidzin, malonylgenistin and malonylglycitin. Total isoflavone contents ranged from 427.92
to 965.89 μg per gram of dry seed and the protein content ranged from 45.17 to 34.95% in BARC-8 and IAC-100, respectively.
Our results indicate that it is possible to select for high isoflavone content in early breeding generations because the broad
sense heritabilities for the contents of the various isoflavone forms were higher than 90%. In addition, high correlation
values among the contents of the individual isoflavone forms were observed (between 0.80 and 0.98). However, negative correlation
values were obtained between isoflavone and protein contents, ranging from −0.51 to −0.37 for the different isoflavone forms.
The correlation value of −0.47 between total isoflavone and protein contents confirmed the negative correlation between these
two parameters, as reported by other authors.

运用关联分析定位栽培大豆蛋白11S、7S组分的相关基因位点 总被引:1,自引:0,他引:1
大豆贮藏蛋白主要成分是7S和11S球蛋白,大豆贮藏蛋白组分及其亚基组成决定了蛋白质的品质和加工特性。本研究选用134对细胞核SSR标记,对166份栽培大豆微核心种质进行基因分型,运用一般线性回归(general linear model, GLM)和复合线性回归(mixed linear model, MLM)方法进行标记与性状的关联分析,定位大豆蛋白亚基的相关基因。结果表明,2年均检测到的且与蛋白亚基相关联的SSR位点有14个,以MLM方法检测到5个SSR位点(Sat_062、Satt583、Satt291、Satt234和Satt595)与蛋白亚基相关联;7S组分各亚基变异程度较大,是引起11S/7S变异的主要原因;表型变异较大的亚基可能因为相关基因进化中发生重组较多,LD衰减距离较小,导致检测到较少的相关位点。本研究结果对蛋白亚基相关性状的标记辅助选择育种有重要的利用价值。 相似文献

Molecular loci associated with seed isoflavone content may underlie resistance to soybean pod borer (Leguminivora glycinivorella) 下载免费PDF全文

Soybean pod borer (SPB) (Leguminivora glycinivorella (Mats.) Obraztsov) causes severe loss of soybean (Glycine max L. Merr.) seed yield and quality in some regions of the world, especially in north‐eastern China, Japan and Russia. Isoflavones in soybean seed play a crucial role in plant resistance to diseases and pests. The aim of this study was to find whether SPB resistance QTL are associated with soybean seed isoflavone content. A cross was made between ‘Zhongdou 27’ (higher isoflavone content) and ‘Jiunong 20’ (lower isoflavone content). One hundred and twelve F5:10 recombinant inbred lines were derived through single‐seed descent. A plastic‐net cabinet was used to cover the plants in early August, and thirty SPB moths per square metre were put in to infest the soybean green pods. The results indicated that the percentage of seeds damaged by SPB was positively correlated with glycitein content (GC), whereas it was negatively correlated with genistein (GT), daidzein (DZ) and total isoflavone content (TI). Four QTL underlying SPB damage to seeds were identified and the phenotypic variation for SPB resistance explained by the four QTL ranged from 2% to 14% on chromosomes Gm7, 10, 13 and 17. Moreover, eleven QTL underlying isoflavone content were identified, and ten of them were encompassed within the same four marker intervals as the SPB QTL (BARC‐Satt208‐Sat292, Satt144‐Sat074, Satt540‐Sat244 and Satt345‐Satt592). These QTL could be useful in marker‐assisted selection for breeding soybean cultivars with both SPB resistance and high seed isoflavone content. 相似文献
