Role of LEAFLESS, an AP2/ERF family transcription factor, in the regulation of trichome specialized metabolism. [PDF]

New Phytol
Summary Acylsugars, specialized metabolites produced by trichomes of many solanaceous species, provide protection against biotic and abiotic stresses. Many acylsugar metabolic enzymes have been identified; however, regulatory factors remain unknown.

Development of transgenic imazapyr-tolerant cowpea (Vigna unguiculata) [PDF]

Plant Cell Reports, 2013
Here we present the development of cowpea lines tolerant to a herbicide from imidazoline class (imazapyr). Plants presented tolerance to fourfold the commercial recommended dose for weed control. Cowpea is one of the most important and widely cultivated legumes in many parts of the world.
