The goal of this project is to lay grounds for transmission genetics in arbuscular mycorrhizal (AM) fungi (Glomeromycota). We use a cosmopolitan species Glomus etunicatum as a model. Our objectives are to investigate: (i) evolution of the ribosomal RNA genes, (ii) the reproductive mode, and (iii) the developmental patterns of spore formation. We discovered that (i) the polymorphism of rRNA genes in the G. etunicatum lineage is inconsistent with the concerted evolution model of rRNA, which is one of the paradigms of evolutionary biology, (ii) the population structure of G.
Improved crop varieties are required to remain competitive in the global economy. Agricultural resources are increasingly allocated to benefit the large producer. However, the growing movement toward consumption of locally grown produce has made small- and medium-sized farms profitable.
The development of strawberry, raspberry and blackberry varieties adapted to temperate climates will help diversified growers remain profitable and competitive with large producers in tropical and subtropical climates.
