| Abstract: | To explore the effect of thrips on amino acid composition and content of alfalfa,the thrips-resistant‘Caoyuan No.4’variety and the thrips-susceptible‘Caoyuan No.2’variety were selected as research material,which were treated with and without Odontothrips loti infestation.The content of 17 amino acids and amino acid derivatives were determined by amino acid analyzer and liquid chromatography-mass spectrometry,respectively.The results showed that:there was no significant difference in the total amino acid content between thrips-resistant alfalfa and thrips-susceptible alfalfa.Thrips feeding led to a significant decrease in the total amino acid content of alfalfa leaves(P<0.05),which mainly included aspartic acid,threonine,serine,glutamic acid and valine.Compared with thrips-sensitive materials,thrips-resistant variety had higher contents of aspartic acid,serine,glutamic acid and tyrosine,while lower contents of threonine,proline,glycine and histidine and arginine.After thrips ingestion,sulfur-containing amino acids(such as methionine,cysteine)or phenyl-ring amino acids(such as phenylacetylglycine and N-phenylacetyl-L-glutamine)increased,while amino related to glutathione metabolism pathway including reduced glutathione glycine,oxidized glutathione,S-methyl glutathione were down-regulated. |
