Human papillomavirus (HPV) vaccines confer protection against the oncogenic genotypes HPV16 and HPV18 through the generation of type-specific neutralizing antibodies raised against the constituent virus-like particles (VLP) based upon the major capsid proteins (L1) of these genotypes. The vaccines also confer a degree of cross-protection against some genetically related types from the Alpha-9 (...

This study aimed to estimate the combining ability, of T. cacao genotypes preselected for drought tolerance through diallel crosses. The experiment was conducted under greenhouse conditions at the Cacao Research Center (CEPEC), Ilhéus, Bahia, Brazil, in a completely randomized block design, in an experimental arrangement 21 x 2 [21 complete diallel crosses and two water regimes (control and str...

the genetic diversity of 40 tobacco (nicotiana tabacum l.) cultivars was analyzed using 12 issr primers. thecultivars were evaluated for 14 traits using a simple lattice design (7×7) with two replications. of 149 amplified bands, 142 (95.3%) were polymorphic. maximum and minimum bands were generated by primers ubc825 (17 bands and 94.11% polymorphic) and ubc824 (7 bands and 100% polymorphic), r...

the genetic diversity of 89 flue-cured tobacco varieties was examined using 12 issr primers. these cultivarswere evaluated at the guilan tobacco research center, rasht, iran, using a 7×7 simple lattice design with two replications, and 12 morphological traits. the total number of pcr amplified products was 143 bands ranging from 450 to 3000 bp, of which 108 bands (74.28%) were polymorphic. prim...

The synthesis of 7-substituted 7-deazaguanine and 7-deazaadenine ribonucleosides 1-2, the incorporation of 3a-d into oligonucleotides, and the stability of the corresponding duplexes and base discrimination are described. The pKa values of 3-4 are determined.

Variability, heritability and genetic advance are basic in order to provide information for plant breeding programs. Forty nine upland rice genotypes were tested 7*7 simple lattice design at Fogera Wereta station of Adet Agricultural Research Center 2012/13. The objectives the study estimate variability, tested. Analysis variance revealed that there was highly significant difference among 49 al...
