Potato ( L.) is an important food crop worldwide, and potato cyst nematodes (PCNs) are among the most serious pests. The identification of disease resistance genes and molecular markers for PCN infestation can aid in crop improvement research programs against PCN infestation.

To provide more quantitative insight into this process, we report results using magnetic tweezers that relate mechanical force to conformational changes of FLNa immunoglobulin-like repeats (IgFLNa) 20-21, previously identified as a mechanosensing domain. We determined the force magnitudes required to unfold previously identified structural organizations of the β-strands in the two domains: IgFLNa 20 unfolds at ~15 pN and IgFLNa 21 unfolding requires significantly larger forces.
