Ultraviolet B Radiation Triggers DNA Methylation Change and Affects Foraging Behavior of the Clonal Plant Glechoma longituba

Abstract: Clonal plants in heterogeneous environments can benefit from their habitat selection behavior, which enables them to utilize patchily distributed resources efficiently. It has been shown that such behavior can be strongly influenced by their memories on past environmental interactions. Epigenetic variation such as DNA methylation was proposed to be one of the mechanisms involved in the memory. Here, we explored whether the experience with Ultraviolet B (UV-B) radiation triggers epigenetic memory and affects cl… Show more

“…Yet, no significant DNA methylation changes could be observed between primed and unprimed plants, and mutants affected in DNA methylation deposition, maintenance or removal, displayed no priming defects in this study (Ganguly et al, 2019). The latter observation suggests the existence of a light priming mechanism independent of DNA Long-term, transgenerational, memory of UV-B exposure has also been unveiled in the clonal plant Glechoma longituba (ground ivy), in which parental ramets exposed to UV-B produce offspring ramets manifesting an 'escape strategy' when foraging in a UV heterogeneous environment, whereas ramets from 'na€ ıve' parents do not show any behavioral preference (Quan et al, 2021). In this study, UV-B stress reduced overall DNA methylation level in parental ramets, a hypomethylation event that appears to be maintained in offspring ramets.…”

“…Long‐term, transgenerational, memory of UV‐B exposure has also been unveiled in the clonal plant Glechoma longituba (ground ivy), in which parental ramets exposed to UV‐B produce offspring ramets manifesting an ‘escape strategy’ when foraging in a UV heterogeneous environment, whereas ramets from ‘naïve’ parents do not show any behavioral preference (Quan et al ., 2021 ).

“…The compensation for biomass loss of offspring plants under stress is not only driven by the environment offspring plants experience, but it can also be driven by their parents (Latzel et al, 2010;Quan et al, 2021). The environmental stress experienced by parental plants can form a kind of "memory, " which affects seeds and the growth performance of offspring plants (Bossdorf et al, 2009;Li et al, 2021;Waterman and Sultan, 2021).…”

“…The effect of parental UV-B on the growth of offspring ramets in a heterogeneous UV-B environment was investigated in our previous studies on Glechoma longituba (Quan et al 2021;Zhang et al 2021). The results suggested that parental UV-B exposure strongly influenced the growth and foraging behaviour of clonal offspring.…”
