Bioactiphore

WebJan 15, 2024 · Through successive simplification of the SL skeleton, and an evaluation of the stimulatory activities of the resulting compounds, it was concluded that the bioactiphore of SLs resides in the CD part of the molecule; in particular, the methyl substituent in the D-ring at C-4 is essential for bioactivity, and thus the D-ring should be present in SLs. WebFeb 17, 2024 · Strigolactones (SLs) represent a class of plant hormones that regulate developmental processes and play a role in the response of plants to various biotic and abiotic stresses. Both in planta hormonal roles and ex planta signalling effects of SLs are potentially interesting agricultural targets.

WebOct 3, 2024 · The region connecting the core (ABC) with the D ring acts as the bioactiphore (Zwanenburg et al. 2009). Endogenous SLs are classified into two main types (strigol and orobanchol type) based on whether the C ring is α- or β-oriented (Cui. 2014). Strigol and orobanchol are canonical SLs as both have A, B, C, and D rings (Butler.
