“…Three hundred fifty-eight of 4,560 vOTUs could be linked to putative hosts, which represents 13.5% of the viral abundance in the six viromes of three lakes. This abundance is lower than in other environments, such as cold, deep-sea seep sediments, suggesting the uniqueness of the viral and microbial communities in the Qinghai-Tibet Plateau lakes (Li et al, 2021). Although most predicted vOTUs were linked to Bacteroidetes (90), Gammaproteobacteria (73), and other bacteria (51), the most abundant vOTUs (35.5% in relative abundance) were linked to Alphaproteobacteria, including the most abundant vOTU (vOTU_1374).…”
