| Abstract |
Abscisic acid (ABA) plays an important role in plant development and adaptation to abiotic stresses. The pyrabactin resistance-like (PYL) gene family has been characterized as intracellular ABA receptors in Arabidopsis. We describe here the functional characterization of PYL3 ABA receptor from a drought-tolerant rice landrace Nagina 22 (N22). The induced expression level of the PYL3 transcript was observed in the N22 under different stress treatments, including cold, drought, high temperature, salt and ABA. In contrast, the expression of PYL3 was down-regulated in drought-susceptible rice cv. IR64 in response to above stresses. C-terminal GFP translational fusion of OsPYL3 was localized to both cytosol and nucleus explaining in part functional conservation of PYL protein as ABA receptor. Arabidopsis transgenic lines overexpressing OsPYL3 were hypersensitive to ABA suggesting ABA signaling pathway-dependent molecular response of the OsPYL3. Further, constitutive overexpression of OsPYL3 in Arabidopsis led to improved cold and drought stress tolerance. Thus, OsPYL3 identified in this study could be a good candidate for genetic improvement of cold and drought stress tolerance of rice and other crop plants. |

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 04 April 2018.
All research outputs
#20,469,520
of 23,028,364 outputs
Outputs from Molecular Biotechnology
#817
of 976 outputs
Outputs of similar age
#292,581
of 331,324 outputs
Outputs of similar age from Molecular Biotechnology
#11
of 14 outputs
Altmetric has tracked 23,028,364 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 976 research outputs from this source. They receive a mean Attention Score of 3.5. This one is in the 1st percentile – i.e., 1% 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 331,324 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 14 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
