Uncultivated species

Inferring phylogenetic trees for newly recovered genomes from metagenomic samples is very useful in determining the identities of uncultivated microorganisms. Even though 16S ribosomal RNA small subunit genes have been established as “gold standard” markers for inferring phylogenetic trees, they usually cannot be assembled very well in metagenomes due to shared regions among 16S genes. Using single-copy marker genes to build genome trees has become increasingly popular for uncultivated species.

Understanding the interaction among different species within a community and their responses to environmental changes is a central goal in ecology. However, defining the network structure in a microbial community is very challenging due to their extremely high diversity and as-yet uncultivated status.

Mycoplasmas are one of the smallest bacteria and are divided into two groups, haemotropic and non-haemotropic mycoplasmas. Hemotrophic mycoplasmas (hemoplasmas) are uncultivable cell wall-less bacteria, previously known as Haemobartonella and Eperythrozoon species. They are gram-negative, obligate red cell parasites and it is considered as pleomorphic. They can be seen as rod, spherical, or ring-shaped organisms and are found individually or in chains across the red cell surface. Hemoplasmas can cause acute hemolytic anemia in dogs and cats.

Rice is a staple food for human being all over the world and India is the second largest producer and consumer of rice at global level. Production of rice in India is limited by several biotic and abiotic factors. Rice sheath blight (Rhizoctonia solani AG1-IA) is one of the most important factor causes significant grain yield and quality losses at worldwide. Yield losses of up to 50% have been reported under most conducive environments in India. Several uncultivated (weeds) and cultivated plant species are known to act as alternate and collateral hosts of R.

Tomato (Solanum lycopersicum L.) is one of the most important vegetable crops under solanaceous group which can be grown both under open field conditions and greenhouses. Tomato has achieved high popularity especially in the recent years because of lycopene’s anti-oxidative activities and anti-cancerous functions. The cultivated tomato has been used in genetic studies because of the ease with which it can be easily manipulated and also its diversity present within the population.
