Research Question: How can microarray technology be used to study gene expression patterns and identify functional categories in plants, specifically loblolly pine seedlings, under drought stress conditions?

Methodology: The researchers developed a system called Expresso for microarray experiment management. This system supports clone replication and randomized placement, automatic gridding, extraction of expression data from each spot, and quality monitoring. It also provides flexible methods of combining data from individual spots into information about clones and functional categories. The analysis used inductive logic programming for higher-level data analysis and mining. The study involved 384 pine cDNAs replicated and randomly placed in two specific microarray layouts.

Results: The results suggest the importance of molecular chaperones and membrane transport proteins in mechanisms conferring successful adaptation to long-term drought stress. This study provides valuable insights into the functional genomic responses to drought stress in loblolly pine seedlings.

Implications: The development of Expresso and the results of the study demonstrate the potential of microarray technology for studying gene expression patterns and identifying functional categories in plants. This can lead to a better understanding of plant responses to stress conditions and potentially improve the resilience of plants to environmental challenges.
