Plant microRNAs play important roles in plant growth and development. Here we investigated the roles of miRNAs in the plant abiotic stress, development and viral infection. MicroRNA membrane array analysis using five different abiotic stress treatments resulted in the identification of 8 novel stress inducible miRNA-families. Functional studies on novel stress inducible miR168 revealed its functional relation with abiotic stress. Over expression of miR168 in Arabidopsis showed upregulation of four stress related miRNAs (miR163, miR167, miR398 and miR408). Analysis of 9 independent transgenic lines showed induction of miR398, an oxidative stress responsive miRNA with a corresponding down regulation of its …

This universally accessible, Web-based decision case presents the challenge of determining the cause of foliar chlorosis in a crop of dicentra (Dicentra spectabilis) being forced as a cut flower for Valentine's Day sales. The case study serves as a tool to promote the development of diagnostic skills for production dilemmas, including nutritional disorders, disease problems, and evaluation of the appropriateness of cultural practices, Cut dicentra is a minor crop and standard production practices are not well established. Solving this case requires that students research production protocol, as well as nutritional and pest problems, and determine whether they have …
