| Abstract |
The G1-like gene from the Lycium chinense was cloned and transferred into N. tabacum. Evidence showed that endogenous JA accumulation was crucial to LcGR gene expression in cadmium-stressed L. chinense. Glutathione reductase (GR) plays a vital role in glutathione-ascorbate metabolism and is a key enzyme in maintaining the redox state in plants. Jasmonic acids (JA) are important hormones regulating protective responses against bacteria and mechanic damage in plants. At present, the relationship between the endogenous JA accumulation, the glutathione (GSH) content and GR gene expression in plants under cadmium (Cd) stress has not been elucidated. This study primarily aims to explore their interconnected relations. First, we isolated the GR1-like gene from Lycium chinense (LcGR). Real-time PCR showed that gene LcGR and allene oxide cyclase (LcAOC) (a JA synthesis gene) expression in L. chinense plants was significantly enhanced by CdCl2 and reduced by CdCl2 cotreatment with 12,13-epoxy-octadecenoic acid (EOA), a JA synthesis inhibitor. Meanwhile, the JA content in plants strongly increased under Cd stress and decreased under Cd + EOA treatment, which was in accordance with expression pattern of LcAOC. The function of gene LcGR was confirmed in vitro with E. coli expression system. The subcellular localization in chloroplasts of LcGR gene was proved in Nicotiana tabacum leaves with transient transfection system of Agrobacterium tumefaciens. Furthermore, the overexpression of gene LcGR in the transgenic tabacum led to great Cd-tolerance and higher GSH accumulation. Overall, the results showed that the endogenous JA accumulation in Cd-stressed plants affects the GR expression which is crucial to the GSH accumulation and GSH-dependent tolerance to cadmium in LcGR transformants. |

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 12 August 2020.
All research outputs
#13,044,767
of 22,982,639 outputs
Outputs from Plant Cell Reports
#1,477
of 2,195 outputs
Outputs of similar age
#150,835
of 315,729 outputs
Outputs of similar age from Plant Cell Reports
#30
of 38 outputs
Altmetric has tracked 22,982,639 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 31st percentile – i.e., 31% 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 315,729 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 51% of its contemporaries.
We're also able to compare this research output to 38 others from the same source and published within six weeks on either side of this one. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
