J. Y. Che, Ding, J. J., Liu, C. Y., Xin, D. W., Jiang, H. W., Hu, G. H., and Chen, Q. S., “Quantative trait loci of seed traits for soybean in multiple environments”, vol. 13, pp. 4000-4012, 2014.

Seed length and seed width are an important factor to the soybean yield. So the quantitative trait loci (QTL) location for seed length and seed width could assistant the breeding of soybean. In this study, the QTL underlying seed length and seed width were studied. A recombinant inbred line population of soybeans derived from a cross between the American semi-draft cultivars Charleston and Dongnong 594 were used in 7 environments. The quantitative trait loci underlying seed length, seed width, and seed length/seed width were analyzed by the method of composite interval mapping.

Isolation and expression analysis of the soybean GmPic gene

The differential screening method was used to isolate the soy photoperiodic response-related genes and to further elucidate the molecular mechanisms of the soybean photoperiodic response. The light-sensitive species Zhong Dou 24 was used to receive long-time sunshine, short-time sunshine, and natural sunshine treatment. The cDNA-amplified fragment length polymorphism technique was used to screen the differentially expressed cDNA fragments. The rapid amplification of cDNA end technique was used to isolate the gene.

Genetic analysis of the major gene plus polygene model in soybean resistance to Leguminivora glycinivorella

J. Zhang, Yao, D., Ma, J., Fu, Y. - P., Qu, J., and Wang, P. - W., “Genetic analysis of the major gene plus polygene model in soybean resistance to Leguminivora glycinivorella”, vol. 13, pp. 4983-4989, 2014.

In order to investigate the genetic characteristics of soybean Leguminivora glycinivorella resistance and to improve soybean resistance insectivorous breeding efficiency by applying the multi-generation joint analysis method of the major gene plus polygene model, 5 pedigrees and generations (P1, F1, P2, F2, and F2:3) were used as the materials to perform the soybean L. glycinivorella resistance multi-generation joint analysis. The results showed that soybean resistance to L.

Cloning and functional prediction of differentially expressed genes in the leaves of Glycine max parents and hybrids at the seedling stage

J. Zhang, Yao, D., Wang, P., Guan, S. Y., Ma, J., and Fu, Y. P., “Cloning and functional prediction of differentially expressed genes in the leaves of Glycine max parents and hybrids at the seedling stage”, vol. 13, pp. 5474-5483, 2014.

Here, we compare the molecular mechanism of soybean heterosis through the differential expression of basic cloning. Specifically, we cloned 22 differentially expressed cDNA fragments from hybrid combinations of Jilin 38 x EXP (which had obvious yield advantages) and their parents. In addition, we compared the homology of these fragments and predicted their functions.
