RESUMEN
We identified 18 polymorphic, trinucleotide microsatellite loci for the solitary vespid wasp Monobia quadridens. These markers are to be used for parentage assessment and for studying population structure and inbreeding. Forty-eight diploid females from Southwest Michigan, USA were screened for allelic variation at each locus. Observed heterozygosities ranged from 0.50 to 0.88. The primers were also tested on two other solitary vespid wasps Ancistrocerus adiabatus and Ancistrocerus antilope.
RESUMEN
A beta-glucosidase gene (bglA) from Butyrivibrio fibrisolvens H17c was cloned into the binary vector pGA482 under the control of the 35S Cauliflower Mosaic Virus (CaMV) promoter. A second construct was generated for accumulation of the bglA gene product in the vacuole of transformed tobacco plants. Reverse transcription-polymerase chain reaction analysis demonstrated that the bglA gene was expressed in 71% of cytosol-targeted and 67% of vacuole-targeted transgenic tobacco T(1) plants. T(1) transgenic plants (pGLU100 and pGLU200) exhibited elevated levels of free salicylic acid (SA) with a concomitant significant decrease in the level of glucosylsalicylic acid (GSA) compared to the untransformed tobacco plants and tobacco plants transformed with the empty vector (pGA482). Following inoculation with Tobacco Mosaic Virus (TMV), lesion area was 51% smaller in pGLU100 plants and 60% smaller in pGLU200 plants compared to inoculated untransformed and negative control plants.
