COMPARISON OF C AND N MINERALIZATION AND METAGENOME ANALYSIS OF RHIZOSPHERE SOILS BELONGING TO DIFFERENT COLCHICUM SPP.

This study is aimed at determining the characteristics and microbiota of soil upon which some Turkish Colchicum (Colchicaceae) species naturally grows. For this aim rhizosphere samples balansae Planch., triphyllum Kunze variegatum L. were analysed in research. The carbon mineralization rate C. p<0.05 significantly different from that other two soils. In terms nitrogen mineralization, significant difference exists between all three soils (p<0.001). was found to have highest bacterial diversity. results revealed 254 common soils, 35.60% unique while 21.89% 22.67% respectively. It collected areas close each had number species, distant region shared 75 with 19 balansae. Metagenomics analysis reveals rhizophere variegatum, triphyllum, Actinobacteria dominant phylum level. Likewise, soil, Nitrosocosmicus halophilic Halobacter be archaea. Saccharomycetales detected, Cryptococcus neoformans var. grubii H99 exclusively detected soil. Significant (p<0.05) observed organic (C%) samples. differences content, others available phosphorus content (p<0.05). showed biological as well physico-chemical properties regulate microbial diversity density by extension influences their activity evidently manifests itself mineralisation.
