Emerging concepts of potassium homeostasis in plants.
Ashish Kumar Srivastava,Ashish Kumar Srivastava,Alka Shankar,Anil Kumar Nalini Chandran,Manisha Sharma,Ki-Hong Jung,Penna Suprasanna,Penna Suprasanna,Girdhar K. Pandey,Girdhar K. Pandey +9 more
TL;DR: The complexity of ROS-calcium-hormone signalling network that is responsible for the sensing of K+ deficiency in plants is discussed, together with genetic approaches using K+ transporters that have been used to increase K+-use-efficiency (KUE) in plants, particularly under environmental stress conditions such as salinity and heavy metal contamination.
Comprehensive expression analysis of rice Armadillo gene family during abiotic stress and development.
Manisha Sharma,Amarjeet Singh,Alka Shankar,Amita Pandey,Vinay Kumar Baranwal,Sanjay Kapoor,Akhilesh K. Tyagi,Girdhar K. Pandey +7 more
TL;DR: A genome-wide identification and expression analysis in the rice genome provides a basis for further functional analysis of Armadillo genes under abiotic stress and reproductive developmental condition in the plant lineage.
A rice tonoplastic calcium exchanger, OsCCX2 mediates Ca2+/cation transport in yeast
TL;DR: OsCCX2 can be used as potential candidate for enhancing the abiotic stress tolerance in plants as well as for phytoremediation of heavy metal polluted soil.
Gene Expression Analysis of Rice Seedling under Potassium Deprivation Reveals Major Changes in Metabolism and Signaling Components
Alka Shankar,Amarjeet Singh,Poonam Kanwar,Ashish Kumar Srivastava,Amita Pandey,Penna Suprasanna,Sanjay Kapoor,Girdhar K. Pandey +7 more
TL;DR: The results of this study indicate that potassium deprivation leads to activation of multiple genes and gene networks, which may be acting in concert to sense the external potassium and mediate uptake, distribution and ultimately adaptation to low potassium conditions.
Whole genome transcriptome analysis of rice seedling reveals alterations in Ca2+ ion signaling and homeostasis in response to Ca2+ deficiency
Alka Shankar,Ashish Kumar Srivastava,Akhilesh K. Yadav,Manisha Sharma,Amita Pandey,Vaibhavi V. Raut,Mirnal K. Das,Penna Suprasanna,Girdhar K. Pandey +8 more
TL;DR: A whole genome transcriptome response to short (5 D) and long (14 D) term Ca(2+) starvation and restoration in rice is reported for the first time, to enable to understand how changes in Ca( 2+) concentration or availability are interpreted into adaptive responses in plants.
