in order to evaluate salt (nacl) tolerance in alfalfa (medicago sativa l.) half-sib families, a factorial experiment on the basis of completely randomized design, with 20-25 individuals in pot (replicates) was carried out under field conditions at the research station of university of tabriz. electrophoretic analyses were performed by using 7.5% slab polyacrylamide gels. two antioxidant enzymes...

We present an analysis of 203 completed genomes in the Gene3D resource (including 17 eukaryotes), which demonstrates that the number of protein families is continually expanding over time and that singleton-sequences appear to be an intrinsic part of the genomes. A significant proportion of the proteomes can be assigned to fewer than 6000 well-characterized domain families with the remaining do...

T recent unveiling of President Clinton’s welfare reform proposal marks the beginning of a debate which, before it ends, may affect both the design and financing of many welfare programs. While the administration’s proposal would redesign one of the key programs, Aid to Families with Dependent Children (AFDC), debate has already spread to how welfare is financed. Poverty rates, which are determ...

UNLABELLED More than 20% of all protein domains are currently annotated as "domains of unknown function" (DUFs). About 2,700 DUFs are found in bacteria compared with just over 1,500 in eukaryotes. Over 800 DUFs are shared between bacteria and eukaryotes, and about 300 of these are also present in archaea. A total of 2,786 bacterial Pfam domains even occur in animals, including 320 DUFs. Evoluti...
