This chapter describes a stepwise protocol for Agrobacterium-mediated sorghum genetic transformation. Immature embryos from sorghum plants were used as the target explants. The Agrobacterium strain LBA4404, carrying a "super-binary" vector, was used in this protocol. Agrobacterium co-transformation vectors, one T-DNA containing the selectable marker gene and another T-DNA containing the trait gene(s), were also introduced in sorghum transformation for eliminating the selectable marker gene in the resulting transgenic plants. This chapter provides recommendations for analysis of the transgenic plants to confirm T-DNA integration into the sorghum genome and segregation of the selectable marker gene from the trait gene(s).

Background: Dementia is a growing public health concern with limited effective treatments. Diet may be a modifiable factor that significantly impacts brain health. Mediterranean diet (MeDi) has been suggested to be associated with brain Magnetic Resonance Imaging (MRI) markers related to dementia, but the existing evidence is inconsistent.

Preeclampsia (PE) is a major pregnancy-specific cardiovascular complication posing latent life-threatening risks to mothers and neonates. The contribution of immune dysregulation to PE is not fully understood, highlighting the need to explore molecular markers and their relationship with immune infiltration to potentially inform therapeutic strategies. We used bioinformatics tools to analyze gene expression data from the Gene Expression Omnibus (GEO) database using the GEOquery package in R.

Genomic prediction applies to any agro- or ecologically relevant traits, with distinct ontologies and genetic architectures. Selecting the most appropriate model for the distribution of genetic effects and their associated allele frequencies in the training population is crucial. Linear regression models are often preferred for genomic prediction.
