| Abstract |
Lovastatin is a competitive inhibitor of the enzyme hydroxymethyl glutaryl coenzyme A reductase (HMGR) in cholesterol biosynthetic pathway and hence used in the treatment of hyperlipidemia. In a previous study, we report a tropical soil isolate, Aspergillus terreus (KM017963), which produces ample amount of lovastatin than its counterpart that are endophytic in origin. Bioinformatic analysis of whole genome sequence of A. terreus (AH007774.1), a soil isolate revealed the presence of gene cluster (AF141924.1 & AF141925.1) responsible for lovastatin production, whereas endophytic fungi including a strain of A. terreus showed no homology with the lovastatin gene cluster. The molecular study was also carried out targeting PCR amplification of the two important genes, lovE (a regulatory gene) and lovF (transcriptional regulatory factor) in genomic and c-DNA of soil and endophytic fungi. Expression of the two genes was successful in A. terreus (KM017963), whereas the same was not achieved in endophytic fungi. To further validate our above findings, in the present study, the whole genome sequencing of A. terreus and a selected endophytic fungus, Diaporthe ampelina (Phomopsis) was performed. Lovastatin gene cluster, when aligned on the consensus sequence of both genomes, the entire lovastatin gene cluster was detected in a single scaffold (1.16) of A.terreus genome. On the contrary, there was a complete absence of lovastatin gene cluster in the genome of D. ampelina (an endophyte). The probable reasons for the absence of lovastatin gene cluster in endophytic fungi are discussed. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 September 2017.
All research outputs
#20,879,072
of 23,498,099 outputs
Outputs from Current Microbiology
#1,963
of 2,471 outputs
Outputs of similar age
#277,048
of 316,586 outputs
Outputs of similar age from Current Microbiology
#28
of 36 outputs
Altmetric has tracked 23,498,099 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,471 research outputs from this source. They receive a mean Attention Score of 3.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 316,586 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 36 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
