Experiment:14
Title:Control of lignification
Date:2004-03-01
Description:Lignin is a carbon rich polymer that is embedded in the cell walls of specialised plant cells. The metabolic cost of making lignin is very high. Therefore lignin biosynthesis must be carefully regulated so as to balance the demands of growth and development against the availability of resources to make this compound. Little is known about the signalling mechanisms that underpin this regulation. We have devised experiments which dissect the regulation of lignification. The "base-line" for our analyses are wild-type plants that have been grown in liquid medium in the absence of sugars in the dark. These plants develop a vascular system but do not lignify. We compare plants grown in this way against mutants and transgenic plants that are able to lignify even under these conditions. By comparing these mutants and transgenic plants against the wild type we are able to uncover the regulatory mechanisms that control when and where lignins are made. Our analyses would include:1) wild-type dark grown no sugar 7 days post germination - no lignification 2) wild-type dark grown_plus sucrose 7 days post germination - lignification 3) wild-type light grown no sugar 7 days post germination - lignification 4) wild-type 6 days dark 1 day light grown no sugar- lignification 5) de-etiolated 3 mutant dark grown no sugar 7 days post germination - some lignification 6) de-etiolated 3 mutant dark grown_plus sucrose 7 days post germination - extensive ectopic lignification 7) zebra 1 mutant dark grown no sugar 7 days post germination - strong ectopic lignification 8) zebra 2 mutant dark grown no sugar 7 days post germination - strong ectopic lignification 9) de-etiolated 3 mutant _plus co-suppressed MYB61 dark grown_plus sugar 7 days post germination - low lignification - two lines (duplicated) 10) wild-type _plus overexpressed MYB61dark grown no sugar 7 days post germination - ectopic lignification - 3 lines (duplicated) 11) de-etiolated 3 mutant _plus kanamycin dark grown_plus sugar 7 days post germination - wild-type phenotype restored (duplicated) We have already completed this analysis once using Affymetrix GeneRNAs. The results of this analysis have been spectacular and using cluster analysis we have already identified several putative "regulons". In order to validate these data we ask permission to complete a biological replicate of this experiment and to extend our analysis of the transgenic plants to include duplicates of the following: 1) 3 independent lines of MYB61 overexpressing plants 2) 2 independent lines of de-etiolated 3 mutants with MYB61 knocked-out 3) de-etiolated 3 mutant treated with spermidine - restores wild type phenotype This experiment will require 20 RNAs. All plants are in a Col-O background
