原始语种摘要: Abstract(#br)From post-diapause cysts of Artemia franciscana , we defined fourteen LEA (late embryogenesis abundant) and LEA-like genes, including four novel members ( Afrlea1-5 , Afrlea3-5 , Afrlea3-like1 and Afrlea3-like2 ), which were classified into four groups: G1, G3, G3-like (LEA group3-like), and SMP-like (seed-maturation-protein-like), based on their conserved and diversified sequence motifs and amino acid compositions among bacteria, plants, and animals. We also validated six representative genes based on quantitative RT-PCR, including three LEA and two LEA3-like genes that are down-regulated when dehydrated cysts hatch to desiccation-intolerant larvae as well as one SMP-like gene that is slightly up-regulated. We further tested their responses to hypersaline stress for four...
