The approximate number and molecular weight of pea seedling ribosomal proteins were determined by twodimensional electrophoresis on polyacrylamide gels containing either urea or sodium dodecyl sulfate. The small (40 S) ribosomal subunit contained 32 to 40 proteins and the large (60 S) subunit 44 to 55 proteins. The great majority of ribosomal proteins were basic and had molecular weights betwee...

a proteomic approach was conducted to further understand the mechanism of plant responses to salinity in hordeum bulbosom. three-week-old seedlings were treated with 300 mm of nacl for 21 days. total proteins of fourth leaf were extracted and separated by two-dimensional gel electrophoresis. more than 500 protein spots were reproducibly detected, including 46 spots that were up-regulated and 16...
