| Abstract |
This research reveals the different expression patterns of anthocyanin biosynthesis enzyme genes and transcription factors in six red-skinned pear cultivars with different genetic backgrounds. Skin color is an important feature of pear fruits, with red skin generally attracting consumers. However, great differences of coloration exist in different pear cultivars. To elucidate the characteristics of pigmentation in pear cultivars with different genetic backgrounds, six cultivars, belonging to P. communis, P. pyrifolia, P. ussuriensis, P. bretschneideri, and a hybrid of P. communis × P. pyrifolia, were used to detect pigment concentrations, expressions of seven anthocyanin biosynthesis enzyme genes, and three related transcription factor genes. Results showed that the occidental pears 'Starkrimson' and 'Red Bartlett' colored at the beginning of fruit setting, but color decreased with fruit maturity; the other four cultivars showed low anthocyanin accumulations and the contents increased during fruit development, but also decreased at later stages. The expression patterns of genes encoding enzymes indicated that ANS and UFGT were decisive genes for anthocyanin biosynthesis for red-skinned pear, and their different expressions led to the coloration differences between occidental and oriental pears. The expression patterns of transcription factors indicated that the different co-expression of MYB10 and bHLH33 genes and the different expressions of WD40 are involved in the differential regulation mechanisms of anthocyanin biosynthesis and coloration pattern between occidental and oriental pears. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 21 October 2015.
All research outputs
#20,239,689
of 22,766,595 outputs
Outputs from Plant Cell Reports
#1,985
of 2,180 outputs
Outputs of similar age
#215,760
of 258,576 outputs
Outputs of similar age from Plant Cell Reports
#16
of 26 outputs
Altmetric has tracked 22,766,595 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,180 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 1st percentile – i.e., 1% 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 258,576 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 26 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
