This paper presents the effects of organic fertilizers on the yield, quality, and fatty acid composition of maize and soybean in 2022 in Southeast Kazakhstan. Maize and soybean yields were improved by commercial organic fertilizers. In general, the yield, quality, and fatty acid (FA) parameters of both crops were influenced by various types of organic fertilizers. The application of HansePlant fertilizer allowed for an increase in the yield of maize seed by 47% and soybean by 31%. Organic fertilizers improved the quality parameters fat, protein, fiber, and starch in maize by 35%, 22%, 14%, and 8%, respectively, compared to control samples. In soybean, the parameters fat, protein, and fiber were improved by 20%, 3%, and 11%, respectively. The FA compositions of maize and soybean were analyzed via gas chromatography and with tandem mass spectrometer using a polarity column. Compared with no fertilization conditions, the omega-6/omega-3 ratio showed the lowest value in maize (22.40–123.96) and soybean (3.26–4.07). A study of the fatty acid composition groups compared with different fertilizer treatments was performed.

“…As shown in Table 1, agricultural producers in Kazakhstan use small amounts of mineral fertilizers. About 83% of crops are not fertilized at all, although this figure increased more than 2.1 times, reaching 16.6% throughout the country [24]. The main types of fertilizer are nitrogen and phosphorus.…”

“…The hybrids from the hybridization between B. rapa and B. napus had been reported to be more viable, precocious, and have higher drought tolerance [36][37][38][39]. Brassinolides are critical plant growth regulators and play an essential role in the growth and development of Brassica and disease resistance [40][41][42][43].…”

Interspecific crosses that fuse the genomes of two different species may result in overall gene expression changes in the hybrid progeny, called ‘transcriptome shock’. To better understand the expression pattern after genome merging during the early stages of allopolyploid formation, we performed RNA sequencing analysis on developing embryos of Brassica rapa, B. napus, and their synthesized allotriploid hybrids. Here, we show that the transcriptome shock occurs in the developing seeds of the hybrids. Of the homoeologous gene pairs, 17.1% exhibit expression bias, with an overall expression bias toward B. rapa. The expression level dominance also biases toward B. rapa, mainly induced by the expression change in homoeologous genes from B. napus. Functional enrichment analysis revealed significant differences in differentially expressed genes (DEGs) related to photosynthesis, hormone synthesis, and other pathways. Further study showed that significant changes in the expression levels of the key transcription factors (TFs) could regulate the overall interaction network in the developing embryo, which might be an essential cause of phenotype change. In conclusion, the present results have revealed the global changes in gene expression patterns in developing seeds of the hybrid between B. rapa and B. napus, and provided novel insights into the occurrence of transcriptome shock for harnessing heterosis.

“…Moreover, the introgression itself can have a dramatic effect on the recombination landscape around the introgression region in the recipient species ( Rodgers-Melnick et al, 2015 ). In crops where double haploid production protocols are established, a genotype could be fixed at a homozygote state quickly once the introgressed region around the beneficial variant is minimized ( Daurova et al, 2020 ). The development of high-resolution markers that are tightly linked to the causative mutation is important to track the course of introgression throughout the breeding process.…”

The diversity observed among crop wild relatives (CWRs) and their ability to flourish in unfavorable and harsh environments have drawn the attention of plant scientists and breeders for many decades. However, it is also recognized that the benefit gained from using CWRs in breeding is a potential rose between thorns of detrimental genetic variation that is linked to the trait of interest. Despite the increased interest in CWRs, little attention was given so far to the statistical, analytical, and technical considerations that should guide the sampling design, the germplasm characterization, and later its implementation in breeding. Here, we review the entire process of sampling and identifying beneficial genetic variation in CWRs and the challenge of using it in breeding. The ability to detect beneficial genetic variation in CWRs is strongly affected by the sampling design which should be adjusted to the spatial and temporal variation of the target species, the trait of interest, and the analytical approach used. Moreover, linkage disequilibrium is a key factor that constrains the resolution of searching for beneficial alleles along the genome, and later, the ability to deplete linked deleterious genetic variation as a consequence of genetic drag. We also discuss how technological advances in genomics, phenomics, biotechnology, and data science can improve the ability to identify beneficial genetic variation in CWRs and to exploit it in strive for higher-yielding and sustainable crops.
