Project description:ngs2021_19_rhizophagus-responses of maize to the arbuscular fungus rhizophagus irregularis mitigate n deficiency stress-What is the impact of Rhizophagus irregularis on maize transcriptome under different N nutrition conditions, what is the impact of N on R. irregularis transcriptome in maize roots.-After 4 days of germination, maize seeds were sown in pots filled with sterile mix 1:1 clay beads:unfertilized peat. Inoculation performed in 3 times with Rhizohphagus irregularis spores purchased at Agronutrition. First inoculation perfomed with 500 spores/plant at sowing. Two other incoulations performed the following week and 2 weeks later with 100 spore per plant each.
Project description:Arbuscular mycorrhizal symbiosis is a predominant relationship between plant and arbuscular mycorrhizal fungi. To idendify arbuscular mycorrhiza responsive miRNAs, small RNA libraries were constructed in tomato roots colonized with Rhizophagus irregularis and without Rhizophagus irregularis. We identify miRNAs in tomato roots and provide a new profile of tomato miRNAs. And we found that some miRNAs were responsive to arbuscular mycorrhiza by comparing miRNAs in treatment with that in control. Examination of arbuscular mycorrhiza responsive miRNAs in tomato through high-throughput small RNA sequencing of roots with Rhizophagus irregularis and that without Rhizophagus irregularis
Project description:We sequenced Endogenous short RNAs in Mucor circinelloides fungus grown in standard liquid culture. Short RNAs were profiled in wild type, Dicer-like 1 mutant (dcl1-), Dicer-like 2 mutant (dcl2-) and double Dicer mutant (dcl1-/dcl2-) strains. We identified many loci that produced less short RNAs in the dcl2- strain suggesting that DCL2 is the major protein generating short RNAs in Mucor circinelloides.
