Altered expression of the TaRSL2 gene contributed to variation in root hair length during allopolyploid wheat evolution.
Article in Planta, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
MAIN
conclusionAltered expression of the TaRSL2 gene was positively correlated with variation in root hair length during allopolyploid wheat evolution, and overexpression of TaRSL2 in Arabidopsis increases root hair length. Root hairs aid nutrient and water uptake and anchor the plant in the soil. Allopolyploid wheats display significant growth vigor in terms of root hair length compared to their diploid progenitors, but little is known about the molecular basis of variation in root hair length during wheat allopolyploidization. Here, we isolated three orthologs of the Arabidopsis root hair gene ROOT HAIR DEFECTIVE SIX-LIKE 2 (AtRSL2) in allohexaploid wheat, designated TaRSL2-4A, TaRSL2-4B and TaRSL2-4D. The deduced polypeptides of these three TaRSL2 homoeologous genes shared high similarity, and a conserved basic helix-loop-helix (bHLH) domain was present in their C-terminal regions. Notably, the expression of TaRSL2 was positively correlated with root hair length of wheat accessions with different ploidy levels. Moreover, ectopic overexpression of TaRSL2-4D in Arabidopsis could increase root hair length. We found that the transcript levels of TaRSL2 homoeologous genes dynamically changed during allopolyploid wheat evolution, implicating the complexity of the underlying molecular mechanism. Collectively, we propose that altered expression of the TaRSL2 gene contributed to variation in root hair length in allopolyploid wheats.
