Abstract:
... In this study, the mechanisms underlying green flower phenotype of a lily cultivar, ‘Doubleen’, was investigated focusing on jasmonic acid (JA) accumulation. ‘Doubleen’ is a mutant lily cultivar derived from ‘Yelloween’ and has unexpanded, non-pigmented green tepals but lacks the stamen and carpel. ‘Doubleen’ was treated with methyl jasmonate (MeJA) to investigate the subsequent change in floral o ...

Abstract:
... Our understanding of canine coat colour genetics and the associated health implications is developing rapidly. To date, there are 15 genes with known roles in canine coat colour phenotypes. Many coat phenotypes result from complex and/or epistatic genetic interactions among variants within and between loci, some of which remain unidentified. Some genes involved in canine pigmentation have been lin ...

Abstract:
... Gloger's rule is an ecogeographical pattern observed in many vertebrates whereby populations in more humid environments have darker pigmentation than populations in more arid environments. The coat color for several species of temperate bats exhibits this pattern, including the Western Long-eared Bat (Myotis evotis) in coastal versus interior populations. We tested Gloger's rule by comparing the c ...
