Metabolic function in jhum field non-cropped and cropped
soil
A total of 263 KEGG pathways were assigned to the bacterial community.
The most prevalent functions (p < 0.001) for all samples in
the BS were ‘ABC transporter’ along with ‘Amino sugar and nucleotide
sugar metabolism’ and ‘Lippopolysaccarides biosynthesis’ (Fig 7a). Upon
comparison at 95 % confidence interval, we observed that the proportion
of ABC transporters was greater in 5-year fallow period than 20-year
fallow in BS and LARS but was lower in 5-year fallow period than
20-years in SARS and RI. Proportions of pyruvate metabolism pathways
were significantly (p < 0.01) greater in short fallow periods
than long fallow periods in BS and LARS. In contrast, amino sugar and
nucleotide sugar metabolism, lipopolysaccharides biosynthesis, were
significantly greater in long fallow periods (Fig 7a,b). In RI only,
amino sugar and nucleotide sugar metabolism have greater abundance in
long fallow periods. Interestingly BS and LARS have a significantly
higher sequence abundance of Benzoate degradation in short fallow
periods. In contrast, SARS and RI have
greater sequence abundance in long fallow periods (Fig 7a-d).
