| Abstract |
Superoxide dismutase genes were expressed differentially along with developmental stages of fertilized ovules in Xanthoceras sorbifolium, and the XsMSD gene silencing resulted in the arrest of fertilized ovule development. A very small percentage of mature fruits (ca. 5%) are produced relative to the number of bisexual flowers in Xanthoceras sorbifolium because seeds and fruits are aborted at early stages of development after pollination. Reactive oxygen species (ROS) in plants are implicated in an extensive range of biological processes, such as programmed cell death and senescence. Superoxide dismutase (SOD) activity might be required to regulate ROS homeostasis in the fertilized ovules of X. sorbifolium. The present study identified five SOD genes and one SOD copper chaperone gene in the tree. Their transcripts were differentially expressed along different stages of fertilized ovule development. These genes showed maximum expression in the ovules at 3 days after pollination (DAP), a time point in which free nuclear endosperm and nucleus tissues rapidly develop. The XsCSD1, XsFSD1 and XsMSD contained seven, eight, and five introns, respectively. Analysis of the 5'-flanking region of XsFSD1 and XsMSD revealed many cis-acting regulatory elements. Evaluation of XsMSD gene function based on virus-induced gene silencing (VIGS) indicated that the gene was closely related to early development of the fertilized ovules and fruits. This study suggested that SOD genes might be closely associated with the fate of ovule development (aborted or viable) after fertilization in X. sorbifolium. |

Attention Score in Context
This research output has an Altmetric Attention Score of 5. 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 17 February 2020.
All research outputs
#7,229,289
of 23,577,654 outputs
Outputs from Plant Cell Reports
#712
of 2,232 outputs
Outputs of similar age
#145,550
of 442,857 outputs
Outputs of similar age from Plant Cell Reports
#24
of 37 outputs
Altmetric has tracked 23,577,654 research outputs across all sources so far. This one has received more attention than most of these and is in the 68th percentile.
So far Altmetric has tracked 2,232 research outputs from this source. They receive a mean Attention Score of 4.1. This one has gotten more attention than average, scoring higher than 66% of its peers.
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 442,857 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
We're also able to compare this research output to 37 others from the same source and published within six weeks on either side of this one. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
