Strigolactone Signaling in Plants
Strigolactones (SLs) are a new group of recently described phytohormones. They were found to be involved in the communication between plant roots and symbiotic bacteria or fungi, but also in the interactions between roots of host plants and germinating seeds of parasitic plants. Over the years, however, it has become clear that SLs play a regulatory role in many aspects of plant growth and deve...
متن کاملHost specificity in parasitic plants—perspectives from mistletoes
Host specificity has been investigated for centuries in mistletoes, viruses, insects, parasitoids, lice and flukes, yet it is poorly understood. Reviewing the numerous studies on mistletoe host specificity may contribute to our understanding of these plants and put into context the dynamics at work in root parasitic plants and animal parasites. The mechanisms that determine host specificity in ...
متن کاملChemical genetics and strigolactone perception
Strigolactones (SLs) are a collection of related small molecules that act as hormones in plant growth and development. Intriguingly, SLs also act as ecological communicators between plants and mycorrhizal fungi and between host plants and a collection of parasitic plant species. In the case of mycorrhizal fungi, SLs exude into the soil from host roots to attract fungal hyphae for a beneficial i...
متن کاملConvergent evolution of genomic imprinting in plants and mammals.
Parental genomic imprinting is characterized by the expression of a selected panel of genes from one of the two parental alleles. Recent evidence shows that DNA methylation and histone modifications are responsible for this parent-of-origin-dependent expression of imprinted genes. Because similar epigenetic marks have been recruited independently in plants and mammals, the only organisms in whi...
متن کاملMolecular evolution of two consecutive carotenoid cleavage dioxygenase genes in strigolactone biosynthesis in plants.
Strigolactones are newly discovered plant hormones that perform various functions, from signaling in symbiotic interactions with arbuscular mycorrhizal fungi to controlling outgrowth of axillary buds. We examined the phylogenetic relationships of two carotenoid cleavage dioxygenase genes (CCD7 and CCD8) that are involved in consecutive upstream steps of the proposed strigolactone biosynth...
