“…The genetic control of photoperiodic response of plants to day-length is one of the major causes and limitations for the distribution of soybean crops to higher latitude areas [5]. This also applies to Kazakhstan, a Central Asian country, where very high-yield soybean cultivars are produced and grown in the southern part at 43 • N, but more adapted soybean genotypes with a neutral reaction to photoperiod are required to grow in the northern part with a higher latitude at 50-53 • N [35][36][37].…”

“…Plant genotyping using molecular markers is one of the most rapidly developing areas in plant biology [35] and crop breeding [36], including soybean [37]. Simple sequence repeat (SSR) or microsatellite markers [38,39] are not only 'simple' in their structure but also in the application, where laboratories with regular equipment and tools can carry out routine molecular analyses in various crops including soybean [40].…”

The photoperiodic sensitivity of soybean (Glycine max L.) is one of the limiting factors affecting plant growth and yield. At higher latitudes, early flowering and maturity with neutral reaction to photoperiods are required for adaptation of soybean plants to long-day conditions. Currently, the production and distribution of new varieties of soybeans adapted to widespread agricultural regions in northern Kazakhstan is in strong demand. Eleven soybean hybrid populations were obtained from crosses between 17 parents with four maturity groups, MG 000, 00, 0, and I. Marker-assisted selection (MAS) was assessed for suitable SSR markers and successfully applied for genes E1, E3, E4, and E7, targeting homozygous genotypes with recessive alleles. The identified and selected genotypes were propagated and tested in the conditions of 53° N latitude in the Kostanay region of northern Kazakhstan. Finally, 20 early maturing F4 breeding lines were identified and developed with genotypes e1 e3 E4 e7, e1 E3 E4 e7, and e1 E3 e4 e7, all completing their growth period within 92–102 days. These breeding lines were developed by MAS and should provide very prospective superior varieties of soybean for northern Kazakhstan through a strategy that may be very helpful to other countries with high latitudes.

“…Instead, the C allelic variant in the Guayparime S-10 variety originated from the PI-171443 line, which served as a direct parent in the genetic cross with the Nainari mutant variety during the development of Guayparime S-10. The PI-171443 line carries the Rym1 and Rym2 genes, which confer tolerance to Mung Bean Yellow Mosaic Begomovirus (Rodríguez-Cota et al, 2017;Rani and Kumar, 2020). The allelic contribution of the PI-171443 line to the soybean population in the Mexican dry tropics, is likely associated with an improvement in the reduced activity of the L-2 enzyme in mature grains where Guayparime S-10 exhibited a desirable attribute of low beany or rancid flavor (López-Fernández et al, 2022).…”

Lipoxygenase enzymes encoded by the Lox1, Lox2 and Lox3 genes play a crucial role in soybean grain, particularly in the development of off-flavors. Understanding molecular variation within Lox genes is essential for the improvement of soybean organoleptic traits. This study investigated the genetic variation in the internal regions of the Lox1, Lox2, and Lox3 genes in mature grain of commercially grown soybean cultivars in Mexico. Genomic DNA from a diverse panel of Mexican soybean cultivars was analyzed using resequencing techniques and in-silico analysis. Single nucleotide polymorphisms (SNP) within the Lox1, Lox2, and Lox3 genes were identified and characterized. The findings indicated that Lox3 gene displayed lower genetic variability compared to Lox1 and Lox2 genes, specifically, was identified a total of 26 SNPs in the Lox1 gene, 11 SNPs in the Lox2 gene, and 5 SNPs in the Lox3 gene among the examined cultivars. A non-synonymous SNP variant of the C/C genotype located in exon 6 of the Lox2 gene was associated with a destabilizing effect on the lipoxygenase 2 enzyme in the Guayparime S-10 and Huasteca 300 cultivars. These findings provide insights into the molecular variation of lipoxygenase-associated genes in Mexican soybean cultivars.
