Abstract

Following exposure to light, single-celled spores of the aquatic fern Ceratopteris richardii undergo a series of rapid developmental changes similar to germination in higher plants. To investigate this process, Salmi, et al. tracked gene expression changes over 48 hours post-light exposure using a microarray printed with partially-sequenced Ceratopteris clones. Here, we extend this work by analyzing over-representation of gene ontology terms among differentially up-regulated genes from each time point.
