Molecular-genetic and cytogenetic analyses of cotton chromosome introgression from Gossypium barbadense L. into the genome of G. hirsutum L. in BC2F1 hybrids.

Scientists studied the introgression of alien chromosomes from G. barbadense into G. hirsutum, finding genetic differences and the elimination of certain chromosomes. This work highlights the specific features of chromosome introgression in cotton breeding.

Comparative assessment of the copy number of satellite repeats in the genome of Triticeae species.

The study compared the copy number of satellite repeats in Triticeae species. Different levels of variability were identified, and specific copy numbers were found in certain species. This information can be used for evolutionary and population studies of Triticeae species.

Phaseolus vulgaris mutants reveal variation in the nuclear genome.

This study examined the genome features and DNA damage in common bean varieties from Bulgaria. The findings showed genetic diversity in genome organization and size, as well as DNA damage. This information is important for breeding programs to enhance productivity, adaptability, nutrition, and disease resistance in common bean varieties.

Identification and function analysis of GABA branch three gene families in the cotton related to abiotic stresses.

GABA genes in cotton plants linked to stress resistance, particularly against salt and high temperatures. GABA protects leaves from damage by increasing enzyme activity and reducing reactive oxygen species.

Comprehensive analysis of WOX transcription factors provide insight into genes related to the regulation of unisexual flowers development in Akebia trifoliata.

Scientists studied Akebia trifoliata, a plant with unisexual flowers, and identified 10 genes (AktWOXs) involved in flower development. They found that these genes have stress and hormone response elements. They also discovered that AktKNU inhibits the expression of AktWUS, which affects the formation of unisexual flowers in A. trifoliata.

Dietary inclusion of Withania somnifera and Asparagus racemosus induces growth, activities of digestive enzyme, and transcriptional modulation of MyoD, MyoG, Myf5, and MRF4 genes in fish, Channa punctatus.

This study examined the effects of adding Ashwagandha and Shatavari to the diet of fish. The results showed that the addition of these herbs improved growth indices, increased enzyme activity, and upregulated myogenic regulatory factors. These findings have potential implications for aquaculture.

Role of Brassica rapa SWEET genes in the defense response to Plasmodiophora brassicae.

Scientists studied the interaction between the pathogen Plasmodiophora brassicae and Chinese cabbage plants. The pathogen causes clubroot disease, inhibiting nutrient absorption. The study explores the role of sugar in plant growth and development.

Tandemly duplicated MYB genes are functionally diverged in the regulation of anthocyanin biosynthesis in soybean.

Researchers identified four MYB genes in soybean created by tandem duplication. Three genes promote anthocyanin production, while one is a pseudogene. Functional differences contribute to diverse metabolite accumulation, shedding light on gene duplications in legumes' evolution.
