dioscorea polystachya/proline

OBJECTIVE To establish a method to determine the underivatized glycine (Gly) and proline (Pro) in vinegar turtle shell. METHODS An HPLC-ELSD method was conducted on a Prevail C18 column (4.6 mm x 250 mm, 5 microm) with the mobile phase of acetonitrile and 0.7% trifluoroacetic acid solution

This study presents, for the first time, sequences of five beta-keratin cDNAs from turtle epidermis obtained by means of 5'- and 3'-rapid amplification of cDNA ends (RACE) analyses. The deduced amino acid sequences correspond to distinct glycine-proline-serine-tyrosine rich proteins containing

Lower concentrations of CuSO(4) (25-75 microM) in the MS medium supplemented with 0.1 mg l(-1) IAA+5.0 mg l(-1) Kn+500 mg l(-1) CH+10 mg l(-1) Cyst hyd enhanced the growth of regenerants of Dioscorea bulbifera L. CuSO(4) (75 microM) induced an appreciable diosgenin yield in the regenerants compared

In order to provide the theoretical basis for the Guangfeng medicinal yam( Dioscorea opposita) in field transplanting, the effect of PEG-6000 simulation drought stress on physiological characteristics of Guangfeng medicinal yam plantlets was studied. Using the method of spectrophotometer,the content

The evolution of reptiles, birds, and mammals was associated with the origin of unique integumentary structures. Studies on lizards, chicken, and humans have suggested that the evolution of major structural proteins of the outermost, cornified layers of the epidermis was driven by the
