“…AM symbioses are widely distributed (Smith and Read, 1997) and their effects on plant reproduction and on plant population dynamics are relatively well established for plants with monomorphic breeding systems (Koide, 2000;Koide and Dickie, 2002;and references therein). However, relatively little is known for plants with dimorphic breeding systems, even though around 15% of angiosperms belong to populations with sexually dimorphic breeding systems (Sakai and Weller, 1999).…”

“…Two excellent reviews are already available about the effects of mycorrhizal symbiosis on plant reproduction in monomorphic plants (Koide, 2000) and its implications for plant population dynamics (Koide and Dickie, 2002). In the present review, a new subject is added: the effect of AM on reproduction in plants with dimorphic breeding systems.…”

“…Most of the studies about the effects of mycorrhizas on plant reproduction have focused on monoecious and hermaphroditic species. The mycorrhizal effects observed are largely explained by the improved growth and nutrient uptake of colonised plants compared to non-mycorrhizal plants (Koide, 2000). Nevertheless, it is also possible that changes in host plant hormone levels due to AM symbiosis (Ludwig-Müller, 2000 and references therein) mediate the mycorrhizal effects on plant reproduction, as different hormones affect many plant functions related to reproduction (Davies, 1995).…”

Most plant species grow in association with arbuscular mycorrhizal fungi in their roots forming arbuscular mycorrhizal (AM) symbiosis. The positive effects of this type of symbiosis on plant's performance are well known and established. However, relatively little is known about how AM symbiosis affects plant reproduction, even though reproduction is probably the most important component of life history. This review begins with a summary of the existing data on plants with monomorphic breeding systems, as most of the research has been performed using hermaphroditic and monoecious plants. Later, the limited number of studies examining mycorrhizal effects on plants with dimorphic breeding systems is detailed. Finally, several key areas for future investigations are highlighted. These include examination of the incidence of sex-specific interactions in other plant species with dimorphic systems, the influence of AM symbiosis in seed germination and establishment in plants with different gender, or the study of the mechanisms behind the AM effects seen on plant reproduction. Evidence suggests that AM symbioses are beneficial for plants with monomorphic and dimorphic breeding systems, as AM symbioses improve both sexual and asexual reproduction. However, the effects observed strongly depend on both the plant and the AM fungus species involved. Plant interactions with AM fungi and the outcome of these interactions may further depend on the gender of the host: sex-specific patterns of root colonization and sex-specific benefits from AM symbioses have been reported in several plant species. However, the incidence and the importance of sex-specific relationships between AM fungi and plants are still largely unexplored.Additional key words: clonal growth, plant sexual dimorphism, plant-fungus interactions, sex-specific interactions, sexual reproduction. Resumen Revisión. Efecto de las micorrizas arbusculares en las características reproductivas de las plantas con dimorfismo sexualLa mayoría de plantas crecen en asociación con hongos micorrícicos arbusculares en sus raíces formando micorrizas arbusculares (MA). Los efectos positivos de este tipo de simbiosis para el desarrollo de plantas son bien reconocidos. Poco se sabe de los efectos de las MA sobre la reproducción; aunque sea probablemente el rasgo más importante de la estrategia vital de una planta. Esta revisión detalla los datos disponibles sobre los efectos de las MA en la reproducción de plantas con sistemas de reproducción monomórficos y dimórficos. Se presentan los datos existentes sobre los efectos en la reproducción en plantas con sistemas de reproducción monomórficos, dado que la mayoría de los estudios se han efectuado sobre plantas hermafroditas y monoicas; se detallan los estudios que examinan los efectos de las MA en plantas con sistemas de reproducción dimórf icos; y se proporcionan líneas de investigación futuras. Los datos sugieren que las MA son mayoritariamente beneficiosas tanto para plantas con sistemas monomórficos cómo dimórficos, ya que m...

“…For example, removal of above-ground biomass can cause the plant to preferentially allocate carbon away from the roots to other plant parts, resulting in altered carbon allocation to AMF [179]. Conversely, increased growth of plant reproductive structures results in a greater requirement for resources in order to produce sufficient branches, leaves and roots [229]. Mycorrhizal fungi have been shown to affect economically important plants, for example by improving growth of tomato plants and mineral nutrient content of fruits [230].…”

Plants and arbuscular mycorrhizal fungi have co-evolved over a period of at least 450 million years. This fungal-plant association involves the transfer of carbon to the obligate biotropic fungus, in return for a wide range of beneficial functions. Although this is usually a mutualistic relationship, it can become parasitic to the plant under adverse conditions. Here, the research examining mechanisms by which mycorrhizal associations improve plant fitness is reviewed. Although there is strong evidence that a number of beneficial functions are performed by mycorrhizae, the mechanisms behind these are often not clear. There are numerous factors which influence these mechanisms and their outcomes, one or more of which can be affecting the association simultaneously. The knowledge we have on arbusular mycorrhizal associations with plants could be applied to various land management practices in order to improve soil degradation brought about by anthropogenic activities. These include erosion, drought, nutrient stress and salinization, and are often a result of poor land management. In order to use mycorrhizal fungi as a biomanagement tool, more research is required, particularly in mature field communities over long timescales. There is a need to invest in the development of sustainable agroecological management methods and to design future policy and legislation that encourages large organizations to incorporate more sustainable practices whilst protecting small-scale farmers.

“…The relationship is considered mutualistic: the heterotrophic fungi are fully dependent on the host plant for carbon acquisition and in exchange, fungi uptake and allocate soil nutrients to the plant ( Smith and Read, 2008 ). The importance of AM fungi for plants is widely recognized and well established: because of increased nutrient uptake and other fungal-derived benefi ts such as improved water acquisition, mycorrhizal plants grow usually better and have increased reproductive output than nonmycorrhizal plants ( Smith and Read, 2008 ;Koide, 2010 ). Recently, evidence is accumulating about the existence of sex-specifi c interactions between AM fungi and sexually dimorphic plants (reviewed in Varga, 2010 ).…”

Effects of arbuscular mycorrhizal fungi and maternal plant sex on seed germination and early plant establishment

• Premise of the study: Arbuscular mycorrhizal fungi usually enhance overall plant performance, yet their effects on seed germination and early plant establishment, crucial steps in plant cycles, are generally overlooked. In gynodioecious species, sexual dimorphism in these traits has been reported, with females producing seeds that germinate at a faster rate than seeds from hermaphrodites.• Methods: Using the gynodioecious plant Geranium sylvaticum , I investigated in a greenhouse experiment whether the presence of arbuscular mycorrhizal spores affects seed germination and early plant establishment, examining at the same time whether the sex of the mother producing the seeds also infl uences these parameters and whether sex-specifi c interactions between these two factors exist.• Key results: The presence of arbuscular mycorrhizal spores in the soil decreased seed germination, did not affect plant survival, but did increase plant growth. Moreover, no signifi cant differences in seed traits were detected between the sexes of the plants producing the seeds.• Conclusions: This study demonstrates that arbuscular mycorrhizal fungi may have contrasting effects for plants during early life stages and that mycorrhizal effects can take place even at the precolonization stage.
