1 · What the graph read from it

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.

2 · The registry

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

MAIN

conclusionOf the three functional FPPS identified in maize, fpps3 is induced by herbivory to produce FDP important for the formation of the volatile sesquiterpenes of plant defense. Sesquiterpenes are not only crucial for the growth and development of a plant but also for its interaction with the environment. The biosynthesis of sesquiterpenes proceeds over farnesyl diphosphate (FDP), which is either used as a substrate for protein prenylation, converted to squalene, or to volatile sesquiterpenes. To elucidate the regulation of sesquiterpene biosynthesis in maize, we identified and characterized the farnesyl diphosphate synthase (FPPS) gene family which consists of three genes. Synteny analysis indicates that fpps2 and fpps3 originate from a genome duplication in an ancient tetraploid ancestor. The three FPPSs encode active enzymes that produce predominantly FDP from the isopentenyl diphosphate and dimethylallyl diphosphate substrates. Only fpps1 and fpps3 are induced by elicitor treatment, but induced fpps1 levels are much lower and only increased to the amounts of fpps3 levels in intact leaves. Elicitor-induced fpps3 levels in leaves increase to more than 15-fold of background levels. In undamaged roots, transcript levels of fpps1 are higher than those of fpps3, but only fpps3 transcripts are induced in response to herbivory by Diabrotica virgifera virgifera. A kinetic of transcript abundance in response to herbivory in leaves provided further evidence that the regulation of fpps3 corresponds to that of tps23, a terpene synthase, that converts FDP to the volatile (E)-ß-caryophyllene. Our study indicates that the differential expression of fpps1 and fpps3 provides maize with FDP for both primary metabolism and terpene-based defenses. The expression of fpps3 seems to coincide with the herbivore-induced emission of volatile sesquiterpenes that were demonstrated to be important defense signals.
