Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The mitogen-activated protein kinase (MAPK) phosphatases (MKPs) are important negative regulators in the MAPK signaling pathways, which play crucial roles in plant growth, regulation of development and response to environment stresses. Several MAPKs have been reported to be involved in the drought stress response, however, there is no evidence for the specific function of MKPs in drought stress. Here, a putative MKP in rice ( Oryza sativa ), OsIBR5, was characterized. Expression of OsIBR5 was induced by PEG6000, abscisic acid (ABA) and hydrogen peroxide (H 2 O 2 ). Overexpression of OsIBR5 in tobacco plants resulted in hypersensitivity to drought and H 2 O 2 treatments. Drought and ABA-induced stomatal closure was significantly reduced in OsIBR5 -overexpressing tobacco plants compared with controls. Moreover, OsIBR5 was found to interact with tobacco MAPKs SIPK and WIPK, and drought-induced WIPK activity was impaired in OsIBR5 -overexpressing tobacco plants. These results indicated that OsIBR5 is a MKP which was induced by abiotic stresses and decreased tolerance to drought stress in transgenic tobacco plants.
