Background

Soybean (Glycine max) is an important source of edible vegetable oils and vegetable proteins in the world. Illumination is one of the most important environmental factors influencing the growth and development of soybeans. Soybeans are typically short-day plants, and most soybean varieties have narrow photoperiod adaptability to different latitudes.

The plant type of the crops refers to the overall embodiment of the aspects of the morphological layout, ecological characteristics, physiological characteristics and the like of the plants. The ideal plant type of the crops can improve the leaf area coefficient of the crops, increase the group photosynthetic efficiency and improve the demand relationship of the crops on fertilizers, thereby improving the yield of the crops. Soybeans are typically short-day plants, and most soybean varieties have narrow photoperiod adaptability to different latitudes. In high-latitude areas, soybean varieties with short stalks and short growth periods are generally needed, TL1 is used as a good variety in low-latitude areas, and the phenomenon of serious lodging and low fruiting rate can occur in the high-latitude areas.

In 2010, scientists have completed soybean genome sequencing, so that conditions are provided for gene function research, good genes in soybeans are more convenient to clone, and the molecular mechanism of the soybean strain type is not clear at present. With the continuous development of molecular biology, the research on plant type functional genes is carried out by utilizing high-throughput sequencing and transgenic technology, so that the yield of the soybean can be improved.

Example II, application of GmSPA3a/3b gene in regulating flowering and plant height of soybean

1. Phenotypic observation of flowering time and plant height in field

The experiment included three replicates. Data were processed using SPSS11.5 statistical software and experimental results were expressed as mean ± standard deviation, with One-way ANOVA test, P < 0.05 (x) indicating significant difference from wild-type soybean variety TL1 and P < 0.01 (x) indicating significant difference from wild-type soybean variety TL1 (see amendments to actual conditions).

Respectively mixing wild soybean variety TL1 and T obtained in example I₂The plants of the GmSPA3a/3b gene deletion mutant Gmspa3a, Gmspa3b and Gmspa3ab are sowed in summer in fields with 100 seeds of Beijing (40 degrees 13 '28' N, 116 degrees 33 '37' E), and the flowering phase and the plant height phenotype are observed and counted. The results, by phenotypic observation in the field, indicate that TL1 blooms around 50 days under long-day sunlight, while the flowering time for 2 Gmspa3a mutants (Gmspa 3a-1# and Gmspa3a-2# in FIG. 3), 2 Gmspa3b mutants (Gmspa 3b-1# and Gmspa3b-2# in FIG. 3) and 1 Gmspa3ab mutant (Gmspa 3ab-1# in FIG. 3) is 42-47 days. After the plant is matured, the plant height and the number of main stem nodes are counted, and the result shows that the plant height of TL1 is 80-88 cm; the plant height of Gmspa3a (Gmspa 3a-1# and Gmspa3a-2# in figure 3) is 47-53cm, the plant height of Gmspa3b (Gmspa 3b-1# and Gmspa3b-2# in figure 3) is 55-68cm, and the plant height of Gmspa3ab (Gmspa 3ab-1# in figure 3) is 38-44cm (figure 3). Soybean TL1 variety and 5 GmSPA3a/3b gene deletion mutants Gmspa3a-1#, Gmspa3a-2#, Gmspa3b-1#, Gmspa3b-2#, and,The Gmspa3ab-1# has very significant difference in flowering phase and plant height. Therefore, the loss of function of the GmSPA3a/3b protein can lead to obvious early flowering phase and obvious reduction of plant height of the soybeans.

2. Detection of soybean flowering related gene expression level

Wild soybean variety TL1 of the second three-leaf fully developed (sampled every 4 hours) and deletion mutant T of 3 GmSPA3a/3b genes obtained in the first example were extracted and cultured for 21 days under long-day conditions (12h light/8 h dark)₂RNA of Gmspa3a-1#, Gmspa3b-1#, and Gmspa3ab-1# plants is subjected to fluorescent quantitative PCR detection on soybean flowering related genes (including GmFT2a, GmFT5a, GmFT4, E1, J and GmCCA 1). The qPCR detection primers are respectively as follows:

GmFT2a-qF/R：

5’-GGATTGCCAGTTGCTGCTGT-3’/5’-GAGTGTGGGAGATTGCCAAT-3’；

GmFT5a-qF/R：

5’-AGCCCGAACCCTTCAGTAGGGA-3’/5’-GGTGATGACAGTGTCTCTGCCCA-3’；

GmFT4-qF/R：

5’-TTTGCATGACAAACACTAACCA-3’/5’-TCTTAGAGGAAAAGGAAAACCAGA-3’；

E1-qF/R：

5’-CACTCAAATTAAGCCCTTTCA-3’/5’-CTTATTGTTCATCTCCTCTT-3’；

J-qF/R：

5’-GTCTACCCTGTTCATTTGC-3’/5’-CAGGAACCCTAAAGTCGT-3’；

GmCCA1-qF/R：

5’-CGAAGATCCTGACAGCAAGA-3’/5’-TTCCTTGTCCAAGCCCTATG-3’；

GmActin-qF/R：

5’-CGGTGGTTCTATCTTGGCATC-3’/5’-GTCTTTCGCTTCAATAACCCTA-3’；

GmActin is used as an internal reference gene. Fluorescent quantitative detection results show that compared with a wild soybean variety TL1 (WT in figure 4), flowering promoting factors GmFT2a, GmFT5a and GmCCA1 are obviously up-regulated in Gmspa3a mutants (Gmspa 3a-1#), Gmspa3b mutants (Gmspa 3b-1#) and Gmspa3ab mutants (Gmspa 3ab-1#) in figure 4), and the expression levels of flowering inhibiting factors GmFT4, E1 and J are obviously down-regulated, which indicates that GmSPA3ab influences the soybean flowering phase, can regulate the soybean maturation phase and realize the north lead of the south variety.
