A possible gene involved in starch metabolism.
With the aim of identifying regulatory genes involved in starch metabolism, we have used a bioinformatics approach (MetaOmGraph, url) to evaluate co-expression transcript profiles across multiple conditions. We identified four genes of unknown function that are potentially involved in starch metabolism. We evaluated the phenotype of three independent knockout mutants of a single one of these genes. All three have a similar morphology compared to their corresponding wild type plant across a variety of growth conditions. Starch granule size and shape are unchanged. However, the mutants display an increased starch phenotype. Our data indicate that this gene may play a role in regulation of function of the starch metabolic network.
