Conditional root expansion mutants of Arabidopsis.

Journal Article

Regulation of cell expansion is essential to the formation of plant organs. We have characterized 21 mutations, representing six loci, that cause abnormal cell expansion in the root of Arabidopsis thaliana. The phenotype of these mutants is conditional upon the rate of root growth. Calculation of cell volumes indicated that the mutations resulted in defects in either the orientation or the extent of expansion or in both. Analysis of cortical microtubules in the mutants suggested that a shift in the orientation of cell expansion may not be dependent on a change in the orientation of the microtubules. Double mutant combinations resulted in loss of the conditional phenotype suggesting that the genes may act in a similar pathway or encode partially redundant functions.
