Project description:Through transcriptome profiling using RNA-seq, we investigated the mechanisms behind bacterial endosymbiont (Burkholderia rhizoxinica) control over host (Rhizopus microsporus) reproductive biology. By analyzing differential expression across six different conditions, including fungal opposite mates growing independently with or without endosymbionts, as well as opposite mates growing together with endosymbionts (mating) or without endosymbionts (no mating), we were able to identify that endosymbionts control expression of a Ras signaling protein critical for sexual reproduction in many fungi (Ras2). As little is known regarding sexual reproduction in Mucoromycotina, we also used these data to investigate conservation of sex-related genes across all fungi, as well as predict potential genes involved in sensing of trisporic acid, the mating pheromone used by these fungi. 6 different conditions were analyzed, each consisting of two biological replicates. These included Rhizopus microsporus ATCC52813 (sex +) growing alone with endosymbionts, R. microsporus ATCC52814 (sex -) growing alone with endosymbionts, ATCC 52813 growing alone without endosymbionts, ATCC52814 growing alone without endosymbionts, ATCC52813 and ATCC52814 growing together with endosymbionts (successfully mating), and ATCC52813 and ATCC52814 growing together without endosymbionts (failure to mate). In each condition, fungi were cultivated on half-strength PDA and plugs of mycelium were placed at the edge of the plate. After 6 days, approximately 2.5 cm of tissue were harvested from the center of the plate. Each biological replicate consists of 5 plates which were pooled prior to RNA extraction to ensure sufficient tissue was collected.

Project description:Background: The soil environment is responsible for sustaining most terrestrial plant life on earth, yet we know surprisingly little about the important functions carried out by diverse microbial communities in soil. Soil microbes that inhabit the channels of decaying root systems, the detritusphere, are likely to be essential for plant growth and health, as these channels are the preferred locations of new root growth. Understanding the microbial metagenome of the detritusphere and how it responds to agricultural management such as crop rotations and soil tillage will be vital for improving global food production. Methods: The rhizosphere soils of wheat and chickpea growing under + and - decaying root were collected for metagenomics sequencing. A gene catalogue was established by de novo assembling metagenomic sequencing. Genes abundance was compared between bulk soil and rhizosphere soils under different treatments. Conclusions: The study describes the diversity and functional capacity of a high-quality soil microbial metagenome. The results demonstrate the contribution of the microbiome from decaying root in determining the metagenome of developing root systems, which is fundamental to plant growth, since roots preferentially inhabit previous root channels. Modifications in root microbial function through soil management, can ultimately govern plant health, productivity and food security.
