Time Dynamics

Stress can be remembered by plants in a form of stress legacy that can alter future phenotypes of previously stressed plants and even phenotypes of their offspring. DNA methylation belongs among the mechanisms mediating the stress legacy. It is however not known for how long the stress legacy is carried by plants. If the legacy is long lasting, it can become maladaptive in situations when parental-offspring environments do not match. We investigated for how long after the last exposure of a parental plant to drought can the phenotype of its clonal offspring be altered. We grew parental plants of three genotypes of Trifolium repens for five months either in control conditions or in control conditions that were interrupted with intense drought periods applied for two months in four different time-slots. We also treated half of the parental plants with a demethylating agent (5-azaC) to test for the potential role of DNA methylation in the stress legacy. Then, we transplanted parental cuttings (ramets) individually to control environment and allowed them to produce offspring ramets for two months. The drought stress experienced by parents affected phenotypes of offspring ramets. The stress legacy resulted in enhanced number of offspring ramets originating from parents that experienced drought stress even 8 weeks before their transplantation to the control environment. 5-azaC altered transgenerational effects on offspring ramets. We confirmed that drought stress can trigger transgenerational effect in T. repens that is very likely mediated by DNA methylation. Most importantly, the stress legacy in parental plants persisted for at least 8 weeks suggesting that the stress legacy can persist in a clonal plant Trifolium repens for relatively long period. We suggest that the stress legacy should be considered in future ecological studies on clonal plants.

The Relationship

ABSTRACTPhenotypic plasticity is facilitated by epigenetic regulation, and remnants of such regulation may persist after plasticity-inducing cues are gone. However, the relationship between plasticity and transgenerational epigenetic memory is not understood. Dauer diapause in Caenorhabditis elegans provides an opportunity to determine how a plastic response to the early-life environment affects traits later in life and in subsequent generations. We report that after extended diapause, post-dauer worms initially exhibit reduced reproductive success and greater inter-individual variation. In contrast, F3 progeny of post-dauers display increased starvation resistance and lifespan, revealing potentially adaptive transgenerational effects. Transgenerational effects are dependent on the duration of diapause, indicating an effect of extended starvation. In agreement, RNA-seq demonstrates a transgenerational effect on nutrient-responsive genes. Further, post-dauer F3 progeny exhibit reduced gene expression plasticity, suggesting a trade-off between plasticity and epigenetic memory. This work reveals complex effects of nutrient stress over different time scales in an animal that evolved to thrive in feast and famine.

Üvegházi körülmények között savanyú barna erdotalajban nevelt fehér here (Trifolium repens L.) növények rizoszférájának sókezelés hatására bekövetkezo változását ellenoriztük. Megvizsgáltuk a különbözo sókoncentrációknak (0, 0,2, 0,4, 0,6 és 0,8 tömeg %) a baktériumnépesség összetételére és a különbözo talajenzimek aktivitására gyakorolt hatását.  Megállapítottuk, hogy a talaj sótartalma közvetlenül befolyásolta a rizoszférában található fluoreszkáló pszeudomonaszok csíraszámát. A legsurubb populáció a 0,2% NaCl-ot tartalmazó talajban volt mérheto, ahol a fluoreszkáló pszeudomonaszok között a Pseudomonas putida és a P. fluorescens fordultak elo a legnagyobb számban. A pszeudomonaszok ily módon jól tolerálják a talaj magas NaCl-tartalmát, és gyökérkolonizáló tevékenységet képesek kifejteni a magas NaCl-tartalmú talajban is. A sókoncentráció növelésével kezdetben (a 0,2-0,4%-os tartományban) jelentosen növekedett a dehidrogenáz, kataláz, és ureáz enzimek aktivitása. A proteáz enzimek aktivitásmaximuma a 0,1-0,2% NaCl-koncentráció tartományba esett. A 0,4%-nál magasabb koncentrációkban a kontrollhoz hasonló mértékure csökkent mind a négy enzim aktivitása, és a baktériumok száma is. A foszfatáz- és a b-glükozidáz-tevékenység viszont a NaCl-dózis növelése következtében a koncentrációval arányosan, jelentosen csökkent a kontrollhoz viszonyítva.  Feltételezésünk szerint az enzimaktivitások változását is a sókezelés hatására bekövetkezo mikrobióta összetételének megváltozása okozta.
