“…Schima wallichii (family: Theaceae) is a medium to large-sized evergreen tree with its distribution range from 900 to 2100 m asl along the Himalaya (Nepal, Bhutan, northeast India, east and west China). This tree also grows in abandoned land and forest areas (Hauchhum and Singson 2020 ).…”

Alnus nepalensis and Schima wallichii are native tree species accompanying succession in abandoned agricultural land in the middle mountainous region of central Nepal. To understand how root fungi recover during spontaneous succession, we analyzed the diversity and composition of arbuscular mycorrhizal (AM), ectomycorrhizal (ECM), and total fungi in tree fine roots from three land use types, short-term abandoned land (SA), long-term abandoned land (LA), and regenerated forest (RF) as a reference. Additionally, ECM morphotypes were examined. The results showed different speeds of succession in the studied fungal groups. While the change in the AM fungal community appears to be rapid and LA resembles the composition of RF, the total fungi in the abandoned land types are similar to each other but differed significantly from RF. Interestingly, the relative abundance of Archaeosporaceae followed a trend differing between the tree species (SA < LA in A. nepalensis, but SA > LA in S. wallichii). Unlike AM and total fungi, there was no significant difference in the ECM community of A. nepalensis between land use types, probably due to their low species diversity (9 ECM morphotypes, 31 ECM operational taxonomic units). However, Cortinarius sp. was significantly more abundant in RF than in the other land use types, whereas Alnicola, Tomentella, and Russula preferred young stages. Our results suggest that for both studied tree species the AM fungal succession could reach the stage of regenerated forest relatively fast. In the case of total fungi, because of hyperdiversity and composed of species specialized to a variety of environments and substrates, the transition was expected to be delayed in abandoned land where the vegetation was still developing and the ecosystem was not as complex as that found in mature forests.

“…Based on flowering, 67 genera of woody bamboos have been placed in the nine sub-tribes (Dransfield andWidjaja 1995 andLi 1997). India is the second-largest reservoir of bamboos with a total of 136 bamboo species belonging to 23 genera (Hauchhum and Singson 2019). Most bamboo species flower once in a lifetime and then die.…”

The SNP barcodes are a viable option for identifying cultivars or species, hence to find single nucleotide polymorphisms (SNPs) that can distinguish the complex, the plastid genes (ribulose bi-phosphate carboxylase), Bambusa tulda-longispiculata-nutans-teres rbcL matK (maturase K), and(RNA polymerase C1) were targeted. Through amplification of these plastid genes and sequencing of amplicons, rpoC1 alignment, and mining of the sequence, SNPs were discovered using NovoSNP software. Over 2045 bp sequenced plastid DNA, seven SNPs were identified in targeted three barcode genes. Three SNPs were found in the gene, which was of 868 bp length, whereas two SNPs matK were found in each of the gene's 730 bp and 's 447 bp lengths. Based on that, discovered that differed from all other rbcL rpoC1 B. nutans species in terms of SNPs present in the and genes, but was determined to be distinct from all three species with rbcL rpoC1 B. longispiculata respect to SNPs present in the gene. Out of seven identified SNPs, the unique heterozygous nucleotide A/G at locus 520G/A and the matK nucleotide 'C' at locus 713 bp were observed in which were absent in all the other three species. These identified Bambusa longispiculata, SNPs can be utilized to differentiate these taxonomically closely related bamboo species.
