| Abstract |
A DRT protein was identified and proved to be involved in the poplar arsenic resistance through comparative proteomics analysis between arsenic sensitive and resistant cultivars. Arsenic pollution in soil has been a serious problem all over the world. It is very important to dissect plants arsenic stress-response mechanisms in phytoremediation. In this study, arsenate-tolerant Populus deltoides cv. 'zhonglin 2025' and arsenate-sensitive Populus × euramericana cv. 'I-45/51' were screened from 10 poplar varieties. Systematic comparisons between these two cultivars demonstrated that 'zhonglin 2025' exhibited slighter morphological and structural injury, lower ROS and MDA accumulation, and higher photosynthesis and ROS scavenging ability under arsenate stress, compared with 'I-45/51'. Through comparative proteomics analysis, we detected that most of the identified arsenate-responsive proteins were stress and defense related. Among these proteins, PdDRT102 was found to be only highly induced in 'zhonglin 2025' under arsenate stress. Heterologous over-expression of PdDRT102 in Arabidopsis conferred to enhanced tolerance to arsenate and sodium chloride. PdDRT102 localizes to the plasma membrane and the nucleus in Arabidopsis. Interestingly, the remarkably increased fluorescence protein signals in the nucleus were found during arsenate stress. Together, these results not only provided an overall understanding on poplar response to arsenate stress, but also revealed that DRT102 protein might involve in protecting poplar against this stress. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. 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 03 May 2021.
All research outputs
#13,214,842
of 22,997,544 outputs
Outputs from Plant Cell Reports
#1,508
of 2,195 outputs
Outputs of similar age
#139,282
of 287,821 outputs
Outputs of similar age from Plant Cell Reports
#29
of 39 outputs
Altmetric has tracked 22,997,544 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,195 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 30th percentile – i.e., 30% 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 287,821 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 50% of its contemporaries.
We're also able to compare this research output to 39 others from the same source and published within six weeks on either side of this one. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
