A Pectin Methylesterase Is Expressed in Silks and Maps to that Locus in Maize ( L.).

The locus of maize confers unilateral cross incompatibility, preventing cross pollination between females carrying the incompatible allele and males not carrying a corresponding compatible allele. To characterize this system at the molecular level, we carried out a transcript profiling experiment in which silks from near isogenic lines carrying the and alleles were compared. While several differentially expressed genes were identified, only one mapped to the known location of .

Digestion of glycogen by a glucosidase released by Trichomonas vaginalis.

Trichomonas vaginalis is a protozoan parasite that is the causative agent of trichomoniasis, a widespread sexually transmitted disease. In vitro culture of T. vaginalis typically employs a medium supplemented with either maltose or glucose and carbohydrates are considered essential for growth.
