Screening of optimal reference genes for qRT-PCR and preliminary exploration of cold resistance mechanisms in Prunus mume and Prunus sibirica varieties.

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
Prunus sibirica and Prunus mume are closely related plant species that differ in cold tolerance. Hybrids of P. sibirica and true mume, belonging to the apricot mei group, inherited strong cold resistance from P. sibirica. These materials are favourable for research on the molecular mechanisms of cold resistance. However, no suitable reference genes have been identified for analysing gene expression patterns between P. sibirica and P. mume. Ten candidate reference genes were assessed, namely, actins (ACT2-1, ACT2-2, ACT2-3, ACT2-4), protein phosphatase 2A-1 (PP2A-1), ubiquitins (UBQ2, UBQ3), ubiquitin extension protein (UBQ1) and tubulins (TUB1, TUB2), with four distinct algorithms (geNorm, NormFinder, BestKeeper and RefFinder). UBQ2 was recognized as the best reference gene in stems and buds across materials (P. sibirica; 'Xiaohong Zhusha', 'Beijing Yudie', and 'Xiao Lve' for true mume; and 'Dan Fenghou', 'Fenghou', and 'Yanxing' for apricot mei) under cold stress. In addition, the temporal and spatial expression patterns of PmCBF6 and PmLEA10 among seven varieties during winter periods were analysed using UBQ2 as a reference gene. The expression differed significantly among cultivars, which may contribute to their differences in cold tolerance. This paper confirmed the strong cold tolerance of apricot mei. And the best internal reference gene suitable for seven varieties was selected: UBQ2. Based on the above results, the expression of PmCBF6 and PmLEA10 genes during wintering in seven varieties was analysed. The molecular mechanisms of cold resistance were found to be possibly different in different varieties of P. sibirica and P. mume.
