Host-Induced Silencing of Some Important Genes Involved in Osmoregulation of Parasitic Plant Phelipanche aegyptiaca.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Broomrape is an obligate root-parasitic weed that acts as a competitive sink for host photoassimilates. Disruption of essential processes for growth of broomrape using host plant-mediated systemic signals can help to implement more specific and effective management plans of this parasite. Accordingly, we tested the possibility of transient silencing three involved genes (PaM6PR, PaCWI, and PaSUS1) in osmoregulation process of broomrape using syringe agroinfiltration of dsRNA constructs in tomato. The highest decrease in mRNA levels, enzyme activity, and amount of total reducing sugars was observed in Phelipanche aegyptiaca when grown on agroinfiltrated tomato plants by PaM6PR dsRNA construct than control. In addition, PaSUS1 dsRNA construct showed high reduction in mRNA abundance (32-fold fewer than control). The lowest decrease in mRNA levels was observed after infiltration of PaCWI dsRNA construct (eightfold fewer than control). While the highest reduction in PaM6PR and PaSUS1 expression levels was detected in the parasite at 3 days post-infiltration (dpi), the maximum reduction in both of the total reducing sugars amount and M6PR and SUS1 activities was observed at 8 dpi. On the contrary, CWI activity, PaCWI expression level, and amount of total reducing sugars in broomrape shoots simultaneously decreased at the day 3 after the dsRNA construct infiltration against PaCWI. On the whole, our results indicated that the three studied genes especially PaM6PR may constitute appropriate targets for the development of transgenic resistance in host plants using silencing strategy.
