Abstract

Abiotic stresses are serious threats to plant growth, productivity and result in crop loss worldwide, reducing average yields of most major crops. Although abiotic stresses might elicit different plant responses, most induce the accumulation of reactive oxygen species (ROS) in plant cells leads to oxidative damage. L-ascorbic acid (AsA, vitamin C) is known as an antioxidant and H2O2-scavenger that defends plants against abiotic stresses. In addition, vitamin C is also an important component of human nutrition that has to be obtained from different foods. Therefore, increasing the vitamin C content is important for improving abiotic stresses tolerance and nutrition quality in crops production. Here, we show that the expression of AtOxR gene is response to multiple abiotic stresses (salt, osmotic, metal ion, and H2O2 treatment) in both the leaves and roots of Arabidopsis. AtOxR protein was localized to the Endoplasmic Reticulum (ER) in yeast and Arabidopsis cells by co-localization analysis with ER specific dye. AtOxR-overexpressing transgenic Arabidopsis plants enhance the tolerance to abiotic stresses. Overexpression of AtOxR gene resulted in AsA accumulation and decreased H2O2 content in transgenic plants. In this study, our results show that AtOxR responds to multiple abiotic stresses. Overexpressing AtOxR improves tolerance to abiotic stresses and increase vitamin C content in Arabidopsis thaliana. AtOxR will be useful for the improvement of important crop plants through moleculer breeding.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 2. 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 10 October 2016.
All research outputs
#14,638,545
of 23,881,329 outputs
Outputs from BMC Biotechnology
#632
of 937 outputs
Outputs of similar age
#180,504
of 323,104 outputs
Outputs of similar age from BMC Biotechnology
#2
of 15 outputs
Altmetric has tracked 23,881,329 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 937 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.9. This one is in the 32nd percentile – i.e., 32% 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 323,104 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 93% of its contemporaries.
