And subsequent liquid scintillation of 1-min fractions applying the chromatographic technique
And subsequent liquid scintillation of 1-min fractions applying the chromatographic Insulin-like 3/INSL3, Human (HEK293, His) technique described by Peters et al. (2007).Mutant Phenotype Analyses of AtABCC1 and AtABCC2 Knockout PlantsMutant phenotypes have been tested by transferring 2-week-old wild-type and atabcc1 and atabcc2 single and atabcc1atabcc2 double mutant seedlings grown on plates onto plates (see “Plant Material and Development Conditions”) containing 12MS medium (pH five.7) and eight.5 g L21 phytoagar supplemented with 150, 300, or 500 mM mannitol or infused with 400 or 700 g L21 PEG-8000. The PEG-infused plates have been prepared as outlined by a protocol by Verslues et al. (2006) and had estimated final water potentials of 20.7 and 21.7 MPa. The development and look of seedlings have been visually inspected from high-resolution photographs captured every day using a flatbed scanner.Yeast Strains and Expression ConstructsThe yeast (Saccharomyces cerevisiae) expression constructs pNEV-AtABCC1 and pYES3-AtABCC2 (Song et al., 2010) as well as the empty vector pNEV-N (Sauer Plant Physiol. Vol. 163,Burla et al.Quantitative Real-Time PCR for AtABCC1 and AtABCCThree-week-old wild-type Arabidopsis seedlings grown on plates were transferred onto plates containing 12MS medium (pH 5.7) and eight.5 g L21 phytoagar supplemented with 20 mM ABA, 20 mM ABA-GE, 10 mM tetcyclacis, and 20 mM ABA ten mM tetcyclacis. ABA and ABA-GE were diluted from stock solutions described in “Vacuolar ABA-GE Transport Assays.” Tetcyclacis (courtesy of Prof. Wolfram Hartung, University W zburg) was diluted from a 50 mM stock option in DMSO. Seedlings have been incubated for eight h below light inside the exact same chamber utilised for seedling development. Total RNA was then extracted from 3 pooled shoots excised from 3 seedlings in triplicate, employing the Promega SV total RNA isolation kit with on-column DNase remedy following the manufacturer’s instructions. Total RNA (1 mg) was reverse transcribed applying Moloney murine leukemia virus (H2) reverse transcriptase (Promega) and oligo(dT)15 primer within a final volume of 20 mL. Quantitative realtime PCR was performed on an Applied Biosystems 7500 Rapid Real-Time PCR system with software version two.0.four. PCR was performed in triplicate and contained 5 mL of 1:ten (vv) diluted cDNA (corresponding to 20 ng of reverse transcribed mRNA), 10 mL of SYBR Green PCR Master Mix (Applied Biosystems), and 0.25 mM of each and every primer within a final volume of 20 mL. The PCR program consisted of an initial 10 min at 95 followed by 40 cycles of 15 s at 95 and 1 min at 60 . The following intron-spanning primer pairs had been utilised: AtABCC1forward, 59-TATTACCAGAACACATCTCGGGA-39, and AtABCC1-reverse, 59-ACCTTCCATTAATTTCAGCCATCC-39; AtABCC2-forward, 59-TTGATGCTGAGGTCTCTGAGG-39, and AtABCC2-reverse, 59-AGTATCTTAGATCTCCGTAACAGC-39; TUB1-forward, 59-ATGCTGATGAATGCATGGTCC-39, and TUB1-reverse, 59-TTCAAGTCTCCAAAGCTAGGAG-39. Transcript levels have been calculated working with the regular curve strategy (Pfaffl et al., 2001) and normalized with TUB1 (tubulin b-1 chain) expression levels.Supplemental Figure S8.
