Phenotyping and Plant Breeding: Overcoming the Barriers

WebPlant breeding is based on phenotyping, not only because of tradition, but because of essence. Phenotypes are harvested and consumed. A plant phenotype is the result of the interactions between all the micro-and mega-environments encountered by a stationary plant and its genome. Over the recent years we have witnessed an explosion in state-of … WebElucidating the developmental origins of phenotypic variation remains a central aim for evo-devo research. Teeth are particularly rich structures exhibiting abundant phenotypic diversity. Here, we chose an interdisciplinary approach to explore what changes in developmental factors may underlie typical transitions between shark tooth shapes ...
