“…In one such study, adaptive transgenerational effects of drought remained after effects of provisioning were removed via covariate analysis, confirming that the expression of transgenerational plasticity in this system relies on additional mechanisms [24]. Studies in other plant systems have also identified effects of parental environment that are independent of seed provisioning [67][68][69], suggesting that other regulatory mechanisms may be involved in many cases of transgenerational plasticity in plants.…”

Environmental stresses experienced by individual parents can influence offspring phenotypes in ways that enhance survival under similar conditions. Although such adaptive transgenerational plasticity is well documented, its transmission mechanisms are generally unknown. One possible mechanism is environmentally induced DNA methylation changes. We tested this hypothesis in the annual plant Polygonum persicaria, a species known to express adaptive transgenerational plasticity in response to parental drought stress. Replicate plants of 12 genetic lines (sampled from natural populations) were grown in dry versus moist soil. Their offspring were exposed to the demethylating agent zebularine or to control conditions during germination and then grown in dry soil. Under control germination conditions, the offspring of drought-stressed parents grew longer root systems and attained greater biomass compared with offspring of well-watered parents of the same genetic lines. Demethylation removed these adaptive developmental effects of parental drought, but did not significantly alter phenotypic expression in offspring of well-watered parents. The effect of demethylation on the expression of the parental drought effect varied among genetic lines. Differential seed provisioning did not contribute to the effect of parental drought on offspring phenotypes. These results demonstrate that DNA methylation can mediate adaptive, genotype-specific effects of parental stress on offspring phenotypes.

“…This fact was particularly evident in several studies carried out with Plantago lanceolata [Plantaginaceae] (Lacey et al 1997). While temperature effects on germination are mediated by the seed coat, the embryo mediates other, more persistent, effects of temperature on parental effects (Case et al 1996).…”

The seed coat as a modulator of seed-environment relationships in Fabaceae

-(The seed coat as a modulator of seed-environment relationships in .abaceae). The seed coat is one of the main determinants of seed germination, vigor and longevity potentials. It is also intimately associated with temporal and spatial dispersion of seed germination in a large number of plant species. The understanding of its properties and characteristics may explain, anticipate or even allow the modification of seed performance under certain environmental conditions. There is a growing volume of evidence associating seed coat characteristics to specific seed problems. .or example, susceptibility to mechanical damage is related to lignin content of the seed coat, while seed longevity and tolerance to field weathering depends on seed coat integrity. Seed performance in many legumes has been associated with certain seed coat structures, such as the hilum, strophiole and micropyle. In soybean, permeability is also related with porosity, color, and cerosity, that affect seed vigor, storage potential, resistance to shrinking and fungi infection, and to susceptibility to imbibition damage. The understanding of these associations is necessary before genetic alterations through breeding for desirable characteristics and is fundamental for the development and improvement of seed pre-sowing treatments, production, handling and quality evaluation procedures, which may ultimately result in reduction of seed quality losses and increase the efficiency of agricultural production systems.RESUMO -(O tegumento como modulador das relações da semente com o ambiente em .abaceae). O tegumento é um dos principais condicionantes da germinação, do vigor e da longevidade de sementes. A compreensão da sua estrutura e propriedades pode contribuir para explicar, antecipar ou alterar o comportamento de sementes sob determinadas condições ambientais. Grande parte das características do tegumento está associada a problemas específicos apresentados pelas sementes. Assim, por exemplo, susceptibilidade a danos mecânicos está associada ao seu teor de lignina, enquanto que longevidade e potencial de deterioração no campo têm sido relacionados ao grau de permeabilidade do tegumento. Em leguminosas, o grau de permeabilidade da semente está associado ao comportamento de determinadas estruturas presentes no tegumento (hilo, estrofíolo, micrópila). Especificamente no caso da soja, a permeabilidade está também associada à porosidade, cor e cerosidade, que influenciam o vigor, o potencial de armazenamento, o grau de resistência ao enrugamento, à infecção por microorganismos, à danos por embebição, etc. A compreensão destas associações é necessária antes de qualquer tentativa de alteração via melhoramento genético de características indesejáveis, é fundamental ao desenvolvimento e aperfeiçoamento de práticas adequadas de manuseio, produção e de testes de avaliação de qualidade de sementes que poderão resultar na redução de perdas de qualidade de sementes e no aumento da eficiência dos sistemas de produção agrícolas.

“…Transgenerational effects of environmental variation on adult phenotypes, mediated by maternal effects, have been observed in some plants (Miao et al 1991;Case et al 1996; reviews in Roach and Wulff 1987;Bernardo 1996a) but are particularly well documented in animals in which progeny spend a substantial amount of time during development inside of their mother (e.g., mammals, many aphids) or in which parental care is provided after progeny are born or hatched (Riska et al 1985;Cheverud and Moore 1994). However, the persistence of environmental variation across generations appears to be uncommon in animals that lay eggs immediately after fertilization, in which progeny complete development entirely outside of their mother, without parental care (i.e., most animals).…”

Inheritance of Environmental Variation in Body Size: Superparasitism of Seeds Affects Progeny and Grandprogeny Body Size via a Nongenetic Maternal Effect

Abstract.-Maternal effects provide the most common mechanism by which environmental variation in one generation affects the phenotype of individuals in subsequent generations. In egg-laying animals, however, we typically observe that maternal effects can have large influences on early growth (egg size and early development), but these effects gradually disappear and become undetectable by the time progeny mature due to developmental plasticity in progeny. We describe a system in which an environmentally induced reduction in body size is inherited by progeny via a nongenetic maternal effect. The seed beetle, Callosobruchus maculatus, completes development inside a discrete resource package (a seed) selected by its mother. Due to superparasitism in response to low host availability, progeny frequently develop at high densities, resulting in intense larval competition and pupation at a smaller body size. Females reared at higher density (and thus emerging smaller) lay smaller eggs than females reared at lower density. Progeny from these smaller eggs mature at a smaller size than progeny reared from the larger eggs laid by females reared at lower density. Crosses between high and low density lines demonstrated that treatment differences in body size are maternally inherited, confirming that the inheritance of body size variation in part involves an environmentally based maternal effect.
