Do strigolactones play a role in the ascent and attachment behavior of Pisum sativum?
Strigolactones (SLs) are signaling compounds made by plants. They play a crucial role in acting as long-distance signals from root to shoot to coordinate shoot growth with root environmental conditions. Here, we test whether and how SLs play a role in the climbing behavior of pea plants by studying...

| description | Strigolactones (SLs) are signaling compounds made by plants. They play a crucial role in acting as long-distance signals from root to shoot to coordinate shoot growth with root environmental conditions. Here, we test whether and how SLs play a role in the climbing behavior of pea plants by studying the circumnutation of the tendrils using three-dimensional (3D) kinematical analysis. To assess this, we compare the typical behavior of P. sativum, a wild-type plant that produces and perceives SLs, with mutants defective in SLs synthesis or signaling, known as ramosus(rms) mutants. The results indicate that mutant plants seem unable to locate and grasp a potential support. Their movement appears to be disoriented and much less energized. We contend that this research opens new avenues for exploring SLs’ role in plant behavior, a novel lens through which the role of SLs in root-to-shoot communication can be observed and analyzed. |
