Somatic embryogenesis receptor-like kinase( Somatic embryogenesis receptor-like kinases,SERKs)widely present in plants,the heported works found SERKs assume multiple roles in plant life activities,participate in the regulation of plant growth,somatic embryos formed,sensors and other hormones. Through bioinformatics tools SERK classification of plants,the average hydrophobic transmembrane regions and signal peptides were forecasted and analyzed.
