RESUMO

Soybean Glycine max L., paleopolyploid genome, poses challenges to its genetic improvement. However, the development of reference genome assemblies and genome sequencing has completely changed the field of soybean genomics, allowing for more accurate and successful breeding techniques as well as research. During the single-cell revolution, one of the most advanced sequencing tools for examining the transcriptome landscape is single-cell RNA sequencing (scRNA-seq). Comprehensive resources for genetic improvement of soybeans may be found in the SoyBase and other genomics databases. CRISPR-Cas9 genome editing technology provides promising prospects for precise genetic modifications in soybean. This method has enhanced several soybean traits, including as yield, nutritional value, and resistance to both biotic and abiotic stresses. With base editing techniques that allow for precise DNA modifications, the use of CRISPR-Cas9 is further increased. With the availability of the reference genome for soybeans and the following assembly of wild and cultivated soybeans, significant chromosomal rearrangements and gene duplication events have been identified, offering new perspectives on the complex genomic structure of soybeans. Furthermore, major single nucleotide polymorphisms (SNPs) linked to stachyose and sucrose content have been found through genome-wide association studies (GWAS), providing important tools for enhancing soybean carbohydrate profiles. In order to open up new avenues for soybean genetic improvement, future research approaches include investigating transcriptional divergence processes, enhancing genetic resources, and incorporating CRISPR-Cas9 technologies.

RESUMO

The aim of this study is to report the synthesis, characterization, and biocompatibility of lanthanum titanate nanoparticles (LT NPs) in albino mice. Microemulsion method was used to generate LT NPs. Seven-week-old albino mice of both sexes orally received 50 mg/ml saline/kg body weight of nanoparticles for 15 days (group 1) and 29 days (group 2). Control groups were maintained in parallel. Selected behavioral (rotarod, light and dark box, open-field and Morris water maze) tests were conducted, blood biochemical analysis was done, and antioxidants were determined in vital organs of all treatments. Male mice treated with LT NPs for 15 days spent significantly more time in light and less time in dark during light dark box test. While they had made significantly more platform entries and platform maximum visits during acquisition phase of Morris water maze test, they remained unaffected in probe trail performance when compared with control. These male mice had significantly reduced white blood cells, lymphocyte, and monocyte count and significantly increased triglyceride levels in serum than the control group. They had higher level of superoxide dismutase (SOD) in heart and reduced level of malonaldehyde (MDA) in kidney while 15-day LT NP-treated females had significantly higher level of SOD in liver and kidney. Male mice treated with NPs for 29 days had increased anticlockwise rotations during open field, reduced level of triglycerides in serum, and significantly higher level of SOD in kidney and MDA in lungs. In contrast, female mice treated with NPs for 29 days had higher SOD level in liver, kidney, and heart than their control group. Oral supplementation of LT NPs for variable duration improved the exploratory behavior in male but disturbed blood chemistry and antioxidants from vital organs under both experimental conditions.
