Revealing How Plants Cope with Drought, Cold.
In a recent paper published in Proceedings of the Royal Society B, complexity scientist Samuel Scarpino and co-authors explore gene co-expression networks that have evolved to help plants withstand drought and cold.
These two responses differ strategically and in evolutionary age.
Scarpino and co-authors David Des Marais (Harvard University), Rafael Guerrero (Indiana University), and Jesse Lasky (Pennsylvania State University) found that the genes that specifically cooperated during cold mapped to central, broadly networked positions within the roughly 10,000-gene network.
Their distinct organizations also might explain why there is more natural genetic variation in drought hardiness than against cold across Arabidopsis thaliana.
