| Abstract |
In silico identified Gossypium hirsutum ghr-miR166b shows multi-compatible targets in mitochondrial ATP synthase of Bemisia tabaci. Its overexpression in planta has the potential to act as a biopesticide in reducing B. tabaci population, and consequently the spread of whitefly-transmitted plant viruses. Whiteflies (B. tabaci) are hemipterous insects that act as a vector to transmit plant viruses causing enormous losses to the plants. In the present study, G. hirsutum-encoded miRNAs targeting expressed sequence tags (ESTs) of B. tabaci, based on sequence complimentarity and miRNA-target mRNA thermodynamics, were in silico identified. Out of 108 G. hirsutum miRNAs, 55 targeted the protein encoding ESTs. Among them, ghr-miR166b was selected owing to its intrinsic affinity for ATP synthase. Its functional role was validated following expression of ghr-MIR166b (precursor) sequence in G. hirsutum cv. HS6 plants through Agrobacterium-mediated transformation. Total of seven independent transformed (T0) G. hirsutum lines were obtained. The transcript level of ghr-MIR166b in the transgenic lines was observed to be 2.0- to 17-fold higher as compared to non-transformed plants. Northern-blot analysis of small RNAs isolated from the transgenic plants confirmed the presence of the ghr-miR166b. After feeding on the leaves of transgenic line (HS6-166-30) having highest level of ghr-miR166b expression, B. tabaci population was reduced up to 91% as compared to non-transformed leaves. Further, in the whole plant assay, a maximum of 78% B. tabaci mortality was observed in the same line, while there was an increase in B. tabaci population on the non-transformed plants. Our results revealed that ghr-miR166b supposedly targeting ATP synthase gene of B. tabaci, and subsequently its overexpression in planta has potential to act as biopesticide for reducing B. tabaci population and consequently spread of whitefly transmitted viruses. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 22 August 2018.
All research outputs
#14,423,597
of 23,100,534 outputs
Outputs from Planta
#1,735
of 2,742 outputs
Outputs of similar age
#240,087
of 438,898 outputs
Outputs of similar age from Planta
#8
of 34 outputs
Altmetric has tracked 23,100,534 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,742 research outputs from this source. They receive a mean Attention Score of 3.3. This one is in the 34th percentile – i.e., 34% 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 438,898 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 34 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 76% of its contemporaries.
