MeSH headings : Adherens Junctions / metabolism; Animals; Cell Differentiation / physiology; Cell Polarity / physiology; Epithelial Cells / metabolism; Gene Expression Regulation, Developmental / physiology; Lens, Crystalline / embryology; Mice; Signal Transduction / physiology; Wnt Proteins / metabolism; beta Catenin / metabolism
TL;DR: The data indicate that beta-catenin plays distinct functions during lens fiber differentiation and is involved in both Wnt signaling and adhesion-related mechanisms that regulate lens epithelium and early fiber differentiation. (via Semantic Scholar)

Weed control and potato (Solanum tuberosum) tolerance with dimethenamid isomers and other herbicides

American Journal of Potato Research, 81(5), 299–304.

By: R. Richardson* , C. Whaley*, H. Wilson* & T. Hines*

author keywords: common lambsquarters; common ragweed; goosegrass; large crabgrass; weed control
TL;DR: No significant injury was observed from most applications of dimethenamid prior to potato emergence, but injury was 20% to 38% with dimethensamid when emerging potatoes were covered slightly by soil during “drag-off” and rain occurred within 24 h. (via Semantic Scholar)
