Webb11 sep. 2024 · The key and defining step in plant embryogenesis is its initiation from a non-embryonic precursor cell. This process naturally occurs when an egg cell is fertilized, transforming a haploid gamete into a diploid sporophyte. This event most certainly triggers reprogramming of the cellular state, and sets in motion the subsequent steps of embryo ... WebbIn bacteria, autolysins catalyze the hydrolysis of the glycosidic bonds in peptidoglycan (PGN) to facilitate cell wall restructuring processes in growth and cell division . LysMs in eukaryotes are likely the result of a horizontal gene transfer event, and in plants they are often adapted to recognize polysaccharide ligands such as PGN and fungal chitin [ 28 , …
