“…Research shows that, for example, clonal plants can sense the heterogeneity of their microenvironment and make choice between qualitatively different patches by placing ramets to beneficial patches (Bazzaz, 1991;Hutchings and John, 2004;Roiloa and Retuerto, 2012;Oborny and Hubai, 2014;Waters and Watson, 2015). Such foraging behavior likely belongs among the important characteristics enabling the dominance of clonal plants in many ecosystems (Wang et al, 2016;Waters et al, 2016;Dong et al, 2018;Li et al, 2018;Latzel and Münzbergová, 2018;Quan et al, 2018;Chen et al, 2019). Majority of studies explained the microhabitat foraging behavior of clonal plants by morphological plasticity and/or photosynthetic adjustments (Salzman, 1985;Evans and Cain, 1995;Wijesinghe and Hutchings, 1999;Roiloa and Retuerto, 2006a,b,c;Xiao et al, 2006Xiao et al, , 2011Waters and Watson, 2015;Waters et al, 2016;Ye et al, 2015;Quan et al, 2018).…”

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

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 clonal plants’ foraging behavior in an UV-B heterogeneous environment. Parental ramets of Glechoma longituba were exposed to UV-B radiation for 15 days or not (controls), and their offspring ramets were allowed to choose light environment enriched with UV-B or not (the species is monopodial and can only choose one environment). Sizes and epigenetic profiles (based on methylation-sensitive amplification polymorphism analysis) of parental and offspring plants from different environments were also analyzed. Parental ramets that have been exposed to UV-B radiation were smaller than ramets from control environment and produced less and smaller offspring ramets. Offspring ramets were placed more often into the control light environment (88.46% ramets) than to the UV-B light environment (11.54% ramets) when parental ramets were exposed to UV-B radiation, which is a manifestation of “escape strategy.” Offspring of control parental ramets show similar preference to the two light environments. Parental ramets exposed to UV-B had lower levels of overall DNA methylation and had different epigenetic profiles than control parental ramets. The methylation of UV-B-stressed parental ramets was maintained among their offspring ramets, although the epigenetic differentiation was reduced after several asexual generations. The parental experience with the UV-B radiation strongly influenced foraging behavior. The memory on the previous environmental interaction enables clonal plants to better interact with a heterogeneous environment and the memory is at least partly based on heritable epigenetic variation.

“…Cloned plants have strong environmental adaptability and widely exist in natural ecosystems due to the characteristics of life infinity, spatial mobility, reproductive diversity, and resource sharing, etc. In particular, they occupy an advantageous position and play a pivotal ecological role in grassland, tundra, wetlands, waters and other ecological systems [4][5][6][7][8]. Studies on the morphological, physiological and ecological characteristics of clonal growth have been systematically compared [9][10][11][12].…”

“…For example, from woodland habitats to grassland and sandy habitats, the cloned plants adopted the intense foraging strategy of Phalanx to Guerrilla with change of spacer length, internode length and branching angle [32]. Research of the clonal plant growth in heterogeneous environments could characterize the strategies of the selective survival pattern [8].…”

“…However, different plants might have formed the optimal spatial expansion strategy in order to adapt to environmental changes and resist the selection pressure brought by environmental heterogeneity in the long course of evolutionary life history [2,45]. So the studies on the behavior selection of habitats in heterogeneous environments are important to reveal the ecological adaptation strategies of clonal plants [8].…”

The different spatial expansion strategies of clonal plants are the result of their adaptations to extreme heterogeneous environments. In this paper, the spatial expansion strategy and the adaptive responses of Phragmites australis to environmental factors were analyzed by comparing clonal modules along degradation gradients (from wetland ecosystem to desert ecosystem). The results show that: 1) With the deterioration of the environmental conditions, the clonal modules (rhizome internode length, spacer length, primary rhizome length and branch angle) showed a trend of first increasing and then decreasing, but the ramet number showed a trend of decreasing first and then increasing, which turned the survival strategy from "Phalanx" (with cluster distribution and showing the invasion attitude) to "Guerilla" (with discrete distribution and showing the evasive attitude) and then back to Phalanx in the process of space expansion. 2) The clonal modules were significantly different in the heterogeneous environment, and were shown the co-development and trade-off relationships (P<0.05). 3) Soil water content, bulk density, pH value and salinity were the main driving forces-especially soil water content, bulk density and pH values in the middle and deep layers and the soil salinity of each layer were the most important environmental factors. The space expansion strategies of Phragmites australis in an extreme environment complemented the theories of traditional cloning plant ecology. And there was important guiding significance for the management and restoration of the degradation wetlands in arid and semi-arid regions to clarified environmental driving forces of clonal plants in inland river wetlands.
