Quantitative dissection of color patterning in the foliar ornamental coleus.

Coleus (Coleus scutellarioides) is a popular ornamental plant that exhibits a diverse array of foliar color patterns. New cultivars are currently hand selected by both amateur and experienced plant breeders. In this study, we reimagine breeding for color patterning using a quantitative color analysis framework.

Digital Morphometrics of Two North American Grapevines (: Vitaceae) Quantifies Leaf Variation between Species, within Species, and among Individuals.

Recent studies have demonstrated that grapevine ( spp.) leaf shape can be quantified using digital approaches which indicate phylogenetic signal in leaf shape, discernible patterns of developmental context within single leaves, and signatures of local environmental conditions. Here, we extend this work by quantifying intra-individual, intraspecific, and interspecific variation in leaf morphology in accessions of North American and in a common environment.
