Constitutive expression of a peanut ubiquitin-conjugating enzyme gene in Arabidopsis confers improved water-stress tolerance through regulation of stress-responsive gene expression.

Ubiquitin (Ub)-conjugating enzymes (UBCs) are key enzymes involved in ubiquitination. Although UBCs have been shown to play important roles in regulating various aspects of plant growth and development, the role of plant UBCs in abiotic stress response needs to be examined further. Here we report the characterization of a ubiquitin-conjugating enzyme gene AhUBC2 from dehydrated peanut plants.

[Genetic diversity of medicinal plant Lonicera confusa populations revealed by random amplified polymorphic DNA].

Objective: To analyze the genetic diversity and differentiation degree of five Lonicera confusa populations.

Methods: Random Amplified Polymorphic DNA (RAPD) markers were perfomed to amplify the discernible loci.

Results: A total of 100 loci were obtained for all populations using ten primers, 87.
