Project description:Protist predators are the primary agents of top-down control of bacteria and primary producers, and thus key organisms determining the fate and transport of organic matter in nature. In this study, we address the effects of light and silver stress on the mixotrophic protist Poterioochromonas malhamensis by means of mass spectrometry-based label-free proteomics.

Project description:Based on the genome sequencing and gene annotation, we analyzed the alginate lyases and other genes related to alginate metabolism of strain Vibrio sp. C42, with the highest alginate-degrading activity. Combined with proteome measurement, we proposed its alginate metabolic pathways.
Project description:Leishmania donovani WHO reference strain MHOM/IN/80/DD8 and Leptomonas seymouri isolates Ld 2001 and Ld39 were used for proteome analysis which were originally isolated from clinical cases of kala azar patients with different inherent antimonial sensitivities. Ld 2001 was Sb-S and Ld 39 was Sb-R. The genome sequencing of these isolates had confirmed co-infection with Leptomonas.
Project description:Candida lusitaniae is an emerging human opportunistic yeast, which can switch from yeast to pseudohyphae, and one of the rare Candida species capable of sexual reproduction. Its haploid genome and the genetic tools available make it a model of interest to study gene function. This study describes the consequences of DPP3 inactivation on cell morphology and mating, both altered in the dpp3Δ knock-out. Interestingly, reintroducing a wild-type copy of the DPP3 gene in the dpp3Δ mutant failed to restore the wild-type phenotypes. Proteomic analyses showed that about 150 proteins were statistically deregulated in the dpp3Δ mutant, and that most of them did not return to their wild-type level in the reconstituted DPP3 strain. The analysis of the segregation of the dpp3Δ mutation and the phenotypes in the progeny of a cross (between the dpp3Δ knock-out and a wild-type strain) showed that the phenotypes are not linked to dpp3Δ, but to a secondary mutation. Genome sequencing of the dpp3Δ mutant allowed us to identify this secondary mutation.
