Leted and non-deleted versions of an OsGRF4 cDNA had been amplified from NJ6. The resultant amplicons had been inserted in to the pSY-735-35S-cYFP-HA or pSY-736-35S-nYFP-EE vectors37 to generate fusion constructs. Co-transfection of constructs (e.g., those encoding nYFP-OsGRF4 and cYFP-SLR1) into tobacco leaf epidermal cells by Agrobacterium-mediated infiltration enabled testing for protein-protein interaction. Following 48h incubation within the dark, the YFP signal was examined and photographed employing a confocal microscope (Zeiss LSM710). Each and every BiFC assay was repeated at least three occasions. PZ-128 References Relevant primer sequences are provided in Supplementary Info Table 6.Co-immunoprecipitation (Co-IP) and western blotting Full-length OsGRF4, OsGIF1 and SLR1 cDNAs have been amplified, then inserted into either the pUC-35S-HA-RBS or the pUC-35S-Flag-RBS vector as previously described38. A. thaliana protoplasts have been transfected with 100 g of plasmid and after that incubated overnight in low light intensity conditions. Total protein was then extracted from harvested protoplasts by treating with 50 mM HEPES (pH7.5), 150 mM KCl, 1 mM EDTA (pH8), 0.3 Trition-X 100, 1 mM DTT with added proteinase inhibitor cocktail (Roche LifeScience). Lysates were incubated with magnetic beads conjugated with an antiDDDDK-tag antibody (MBL, M185-11) at 4 for at the least 4 hours. The magnetic beads were then rinsed 6 times using the extraction buffer and eluted with 3 lag peptide (SigmaAldrich, F4709). Immunoprecipitates had been electrophoretically separated by SDS-PAGE and transferred to a nitrocellulose membrane (GE Healthcare). Proteins were detected by immunoblot working with the antibodies anti-Flag (Sigma, F1804) and anti-HA (MBL, M180-7). InNature. Author manuscript; readily available in PMC 2019 February 15.Li et al.Pageaddition, the OsGRF4, SLR1, OsLhca1, OsLhca3, OsLhca4, OsLhcb2, OsPsaD and OsPsaE proteins had been detected by probing the membrane with anti-OsGRF4 antibodies (Abmart), anti-SLR1 antibodies (ABclonal Technology), anti-OsLhca1 antibodies (Agrisera, AS01005), anti-OsLhca3 antibodies (Agrisera, AS01007), anti-OsLhca4 antibodies (Agrisera, AS01008), anti-OsLhcb2 antibodies (Agrisera, AS01003), anti-OsPsaD antibodies (Agrisera, AS09461) and anti-OsPsaE antibodies (Agrisera, AS08324A), respectively. Uncropped blots had been shown in Supplementary Details Figure. 1. Relevant primer sequences are given in Supplementary Details Table six. EMSA assays EMSA was performed as previously described with minor modifications39. Full-length OsGIF1 and SLR1 cDNAs had been amplified and cloned into the pCold-TF vector (Takara). His-OsGIF1 and His-SLR1 recombinant proteins were purified using Ni-NTA agarose (QIAGEN, 30210), following the manufacturer’s directions. GST (Glutathione Ch55 Metabolic Enzyme/Protease Stransferase) and GST-OsGRF4 recombinant protein have been expressed in the Escherichia coli BL21 (DE3) strain after which purified applying Glutathione Sepharose 4B beads (GE Healthcare, 17-0756-01). 42 bp DNA probes had been artificially amplified and labelled using a biotin label kit (Biosune). DNA gel shift assays had been performed employing the LightShift Chemiluminescent EMSA kit (Thermo Fisher Scientific, 20148). Relevant primer sequences are offered in Supplementary Info Table 8. RNA-seq evaluation Total RNAs had been extracted from 3-week-old rice plants grown beneath higher N situations (1.25 mM NH4NO3) applying the QIAGEN RNeasy plant mini kit (QIAGEN, 74904) following the manufacturer’s guidelines. Three replicate RNA-seq libraries had been prepared fr.
