Introgression of Herbicide-Resistant Gene from Genetically Modified L. to through Backcrossing.

Interspecific hybridization between two different Brassicaceae species, namely ssp. (♀) (AA, 2n = 2x = 20) and genetically modified (♂) (AACC, 2n = 4x = 38), was performed to study the transmission of a herbicide resistance gene from a tetraploid to a diploid species. Initially, four different GM lines were used for hybridization with via hand pollination.

Unveiling the imprinted dance: how parental genomes orchestrate seed development and hybrid success.

Parental epigenetic asymmetries, which contribute to the monoallelic expression of genes known as imprints, play a critical role in seed development in flowering plants. Primarily, differential DNA methylation patterns and histone modifications on parental alleles form the molecular basis of gene imprinting. Plants predominantly exhibit this non-Mendelian inheritance phenomenon in the endosperm and the early embryo of developing seeds.

Rice transcription factor WRKY114 directly regulates the expression of OsPR1a and Chitinase to enhance resistance against Xanthomonas oryzae pv. oryzae.

Rice (Oryza sativa L.) is a global staple crop, but its yield is severely threatened by bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo).
