S were cultivated in BrightBoy growth chambers (CLF Plant Climatics, Wertingen, Germany) in extended days (16 h 80 mol m-2 s-1 white light/8 h dark) and at a temperature of 21 C C. They had been grown either in sterile conditions on half-strength Murashige and Skoog (MS) medium (39) (with 1 sucrose and 0.eight plant agar) or in soil (SP ED63P, Patzer GmbH, HSP supplier Sinntal-Altengronau). For hypocotyl elongation assays, seeds were plated on MS plates containing 24-epiBL or solvent (dimethyl sulfoxide) in equal quantities as a control, stratified for 48 h at four C, and after that incubated vertically within the light or within the dark (having a prior six h light impulse). The length in the hypocotyls of plants germinated in the identical time was then measured at distinctive time points. For adult plant phenotyping, plants have been pregrown on MS medium and transferred to soil at 5 days post germination.PMAT1 malonylates brassinolide glucosideWestern blot evaluation Five microliter of protein preparations produced inside the wheat germ expression system had been mixed with five l two x SDS buffer (100 mM TRIS/HCl pH six.8, 200 mM DTT, four SDS, 20 glycerol and 0.025 bromophenol blue) and heated to 95 C for three min. Samples were separated on a 10 SDS-PAGE gel and transferred onto a PVDF membrane (Merck Millipore). Immediately after blocking with TBS-T (150 mM NaCl, 10 mM TRIS/HCl pH 8.0, 0.1 Tween 20) containing 5 skim milk powder, the membrane was probed with anti-c-Myc-HRP antibody (cat. sc40 HRP, Santa Cruz Biotechnology) diluted 1:5000 in TBS-T containing 5 skim milk powder. The membrane was washed six instances in TBS-T and one particular time in phosphate buffered saline prior signal detection applying the ECL Pick kit (cat. RPN2235, GE Healthcare). To probe BES1 phosphorylation, opened flowers of adult plants were frozen and ground to a fine powder in liquid nitrogen. Proteins had been extracted by addition of two volumes two x SDS buffer and heating to 95 C for five min. Extracts (7.five l) had been separated on 15 SDS-PAGE gels and blotted and blocked as described above. The membrane was probed having a BES1 antibody (21) 1:2000 in TBS-Tcontaining five skim milk powder at four C overnight. Just after washing six times with TBS-T containing five skim milk powder, the membrane was probed with HRP-conjugated anti-mouse antibody (cat. 61020, Invitrogen) diluted 1:10,000 in TBS-T containing five skim milk powder at 4 C overnight. Final washing and signal detection was performed as stated above. qPCRs RNA isolation, cDNA synthesis, and qPCR was performed as described previously (11). The amplification curves were linear (r2 0.99), plus the primer pairs showed higher efficiency (9505 ). Melting curves confirmed absence of unspecific by-products. Expression levels were normalized for the internal typical GAPC2 and measured in three to four technical replicates.
