Environmental strigolactone drives early growth responses to neighboring plants and soil volume in pea

Cara D. Wheeldon et al.

Summary: Recent studies have made significant progress in understanding how plants detect their neighbors through various mechanisms such as touch, reflected light, volatile organic chemicals, and root exudates. While the importance of root exudates in neighbor detection is still unclear, there is evidence that they can help plants distinguish between kin and non-kin neighbors. Additionally, strigolactones, as plant hormones, may play a crucial role in neighbor detection. These findings contribute to a better understanding of plant interactions and growth regulation.

Strigolactones are chemoattractants for host tropism in Orobanchaceae parasitic plants

Satoshi Ogawa et al.

Summary: Parasitic plants use strigolactones as chemoattractants to locate and grow towards their hosts. The chemotropism to strigolactones is influenced by ammonium ion-rich conditions, resulting in reduced chemotropic ability. There are noticeable differences in the chemotropism to strigolactones between parasitic and non-parasitic plants in the Orobanchaceae family.

9-cis-β-Apo-10′-carotenal is the precursor of strigolactones in planta

Guan-Ting Erica Chen et al.

Summary: This study provides direct evidence for the formation of SLs from 9-cis-beta-apo-10'-carotenal and explores the use of labeled long-chain apocarotenoids as a promising approach to investigate apocarotenoid metabolism and the genesis of carotenoid-derived growth regulators and signaling molecules.
