Once initiated, the development of Fkd vascular bundles is like wild type, generating an open vascular pattern of similar complexity to the closed venation pattern of wild type. Despite the significant alteration in the vascular pattern, Fkd plants are morphologically indistinct from wild type. fkd mutants do not show altered sensitivity to the effects of auxin and show additive phenotypes with auxin response mutants, suggesting the FKD is part of a pathway acting independently of auxin. The similarity of the open vascular pattern of Fkd plants to that of ancestral vascular plants suggests that acquisition of this pathway may have been critical in the evolution of the closed vascular pattern. en_US Leaves -- Physiology Vascular system of plants Plants -- Motion of fluids in Dissertations, Academic Genetic analysis of leaf vascular patterning in Arabidopsis thaliana Thesis 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 URL http://localhost:4000/bitstreams/a666ba02-8169-44c8-bd3d-71f4d88b6620/download File MD5 c0c53ad0ba2f329d5fcc0fbf9065891c 1765980 application/pdf MQ68348.pdf URL http://localhost:4000/bitstreams/7e90e75a-5eee-4b0e-ace7-f2f38d99aa52/download File MD5 050d050bd04c4468cdfdbcc631e68a5a 96014 text/plain MQ68348.pdf.txt
