Ertility, fixed anthers had been ground to release pollen grains and then stained with I I resolution. Blue stained pollen grains were counted to decide pollen fertility. For in situ hybridization experiment, the spikelets at about stage have been collected and fixed in (wv) paraformaldehyde at overnight, followed by a series of dehydration by graded ethanol infiltration and lastly have been embedded in paraffin. Then mm thickness sections had been obtained making use of microtome (Leica). bp of CTBa cDNA was subcloned into pMDT vector and made use of as template to create Mikamycin IA web antisense and sense probes. The digoxingenin labelled probes have been ready A-804598 web applying digoxingenin RNA Labeling Kit (Roche,). Total proteins have been extracted from tobacco leaves expressing Super::AtpBMyc CaMVS::HFCTBaKD or Super:AtpBMycCaMVS::HF utilizing ml of IP buffer (mM Tris Cl, pH mM NaCl, mM MgCl NP, mM DTT and PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/27882223 Protease Inhibitor Cocktail, Roche). Lysates at have been centrifuged at , g for min and ml was taken as input. The left supernatants were incubated with ml HA agarose beads (Sigma, A) at for a minimum of h in a ml medium supplemented with IP buffer. Subsequently, beads had been collected by centrifugation at , g for min, washed 5 instances with IP buffer and eluted with boiled SDS loading buffer. Samples were then separated in SDSPAGE gels and detected by antiMyc (Sigma, M, dilution,) and antiHA antibodies (Sigma, H, dilution,). The original western blot images are supplied in Supplementary Fig Primer sequences are supplied in Supplementary Information . Determination of ATPase activity and ATP content. Panicles and leaves of distinct components under typical and CSPT for days had been sampled for 
determination of ATP synthase activity and ATP content. ATP synthase activity was determined by the protocol offered together with the ATPase Activity Assay Kit (GenMed Scientifics, GMS.). ATP was extracted in lysis buffer (mM Tris Cl, pH mM NaCl, mM EDTA TritonX and glycerol) and quantified based on the requirement of luciferase for ATP in making light following the manufacturer’s protocol supplied with the ATP Determination Kit (Invitrogen, A). A common curve of ATP concentrations from . mM to mM was utilised inside the analysis. Each and every experiment was performed with 3 biological samples, every single with five technical replicates. Measurement of photosynthetic price. The photosynthetic rates of diverse supplies under standard and CSPT situations were measured applying a LICOR CO gas exchange analyser (LICOR, Lincoln, NE). Statistical evaluation was based on data obtained from at the least eight plants of each line. In vitro phosphorylation assay. The kinase activity assays of CTBaKD have been carried out inside a ml reaction mixture containing purified CTBaKDGST (mg) GST (mg), CTBaKDGST (mg)AtpBGST (mg) or GST (mg)AtpBGST. The kinase buffer contained mM Tris Cl (pH .), mM MgCl and mM ATP. The reactions were began by adding mCi of gP ATP as well as the samples were incubated for min at . The reaction was 
stopped by adding ml loading buffer and boiled for min, then the proteins had been separated by SDSpolyacrylamide gel electrophoresis and detected by Typhoon imager (GE Healthcare). Primer sequences are offered in Supplementary Information . Information availability.
