“…Overall, the 95% confidence interval based on binomial distribution was 0.0526 Ϯ 0.0449 between T. matsutake isolates from Japan and those from the rest of Asia. As for the relevancy of the sampling in our studies, the specimens analyzed must be regarded as representing their geographical origins, for extensive diversification of mushroom species generally existing in a local habitat makes the risk of reisolation of the same samples hardly possible (1,2,6,9,14,20,25,27,29,30,33). Nucleotide sequence analysis of the geotype determinants.…”

“…Note that Japanese isolates were collected from various locations between 1983 and 2005, Korean isolates were collected between 1997 and 2006, and Chinese and Bhutanese isolates were collected between 1992 and 2007 ( Table 1). The occurrence of local diversification at the level of isolates has been reported in T. matsutake (14,20,33), and diversification through mosaicism has been documented as a general phenomenon in mushroom-producing basidiomycetes (1,2,9,25,27,29,30). Therefore, the retroelement-based geotyping markers are recognized as highly conserved over generations.…”

The ectomycorrhizal basidiomycete Tricholoma matsutake produces commercially valuable fruit bodies, matsutake, in forests. Here we report a PCR system targeting retroelement integration sites to differentiate among individual Asian isolates of T. matsutake based on their geographical origins, such as Japan, the area of South Korea through North Korea, the northeastern provinces of China, and the area of the southwestern provinces of China through Bhutan. The overall misjudgment rate of the analytical system was approximately 5% based on 95 samples of T. matsutake examined including those from cultures and from commodities. We also provide evidence that T. matsutake isolates grown throughout the Far East, including the northeastern provinces of China, are closely related to each other while distinct from those in the area of the southwestern provinces of China through Bhutan. The method allows us to trace back geographical origins of Asian matsutake, thus contributing to food safety, appropriate tariffs, and proper price setting.

“…In many plants, somatic mutations accumulate between cell lineages (Whitham and Slobodchikoff 1981). Somatic mutations have also been reported in fungi (Peabody et al 2000;Stenlid 2000), red algae (Santelices and Varela 1993;Meneses et al 1999;Santelices et al 1999), invertebrates (Rinkevich and Weissman 1987;Barki et al 2002;Sommerfeldt et al 2003), and vertebrates (De 2011).…”

While numerous criteria have been proposed in definitions of biological individuality, it is not clear whether these criteria reflect the evolutionary processes that underlie transitions in individuality. We consider the evolution of individuality during the transition from unicellular to multicellular life. We assume that "individuality" (however it is defined) has changed in the volvocine green algae lineage during the transition from single cells, to simple multicellular colonies with four to one hundred cells, to more complex multicellular organisms with thousands of differentiated cells. We map traits associated with the various proposed individuality criteria onto volvocine algae species thought to be similar to ancestral forms arising during this transition in individuality. We find that the fulfillment of some criteria, such as genetic homogeneity and genetic uniqueness, do not change across species, while traits underpinning other aspects of individuality, including degrees of integration, group-level fitness and adaptation, and group indivisibility, change dramatically. We observe that different kinds of individuals likely exist at different levels of organization (cell and group) in the same species of algae. Future research should focus on the causes and consequences of variation in individuality.

“…Th ere is some evidence for genetic mosaics in Armillaria fruit bodies (Peabody et al, 2000), for genetically diff erent multiple initiation pathways ( Leslie and Leonard, 1979) and, conversely, for diff erent structures (specifi cally sclerotia and basidiomes) sharing a common initiation pathway (Moore, 1981). Fruiting in haploid, primary homothallic species, such as Volvariella bombycina and V. volvacea (Chang and Yau, 1971;Chiu and Chang, 1987;Royse et al, 1987) and in homokaryons in heterothallic species (Uno and Ishikawa, 1971;Elliott, 1972Elliott, , 1985Stahl and Esser, 1976;Dickhardt, 1983;Graham, 1985) shows that fruiting is independent of the sexual cycle regulated by the incompatibility system in heterothallic species (Kües and Casselton, 1992;Kronstad and Staben, 1997;Casselton and Olesnicky, 1998;Kües et al, 1998;Chiu and Moore, 1999;Kües and Liu, 2000;Brown and Casselton, 2001;Kothe, 2002).…”

ABSTRACT:Research done over the last century has persistently indicated major diff erences between fungi, animals, and plants. Unfortunately, for most of that time fungi have been considered, quite erroneously, to be closely related to plants; as observations have been constrained to comply with this fundamental error, a proper appreciation of fungal developmental biology has been seriously inhibited. During the fi nal quarter of the 20t century, the phylogenetic status of the true fungi as an independent Kingdom of eukaryotes became clear. In this review, I bring together some of the observations, old and recent, that contribute to our current understanding of the way that fungi construct multicellular structures.
