Pheno-transcriptomic characterization of hooked hairs in common bean

This faces a big challenge for agriculture to secure food production in the world. Because of the key role of plant roots in the soil and environment interactions, understanding the cell structures, genetic circuits, and mechanisms controlling the root architecture may help to mitigate these effects.

However, the information about the role of the cell structures composing the root architecture, especially during early developmental stages, is very limited. Here we reported a high-dimensional imaging method to support the existence of a novel root hair-like structure in common bean (Phaseolus vulgaris), named ‘hooked hairs’, by combining with comparative RNA-sequencing analyses to other common bean hair-like structures confirming a distinct transcriptomic landscape with particular pathways enriched.
