Figure Lengend Snippet: Schematic representation of the full-length CrMYC2 protein showing the positions of the potential nuclear localization signal sequences (NLS 1, 2, 3, and 4) and of the regions of CrMYC2 used to make the GFP fusions . NLS: nuclear localization signal, CrMYC2: full-length CrMYC2 sequence, F1 to F8: partial CrMYC2 sequences used for fusion to GFP. Grey box: bHLH domain. Single oval shape: monopartite NLS. Double oval shape: bipartite NLS.

Article Snippet: PCR cycling conditions were as follows: 94°C for 4 min (1 cycle) followed by 94°C for 1 min, an annealing step at various temperatures depending on the T m of the primers used for 1.5 min, and 72°C for 1 min (30 cycles), with a final extension step at 72°C for 5 min. PCRs were performed in a final volume of 25 μl with 0.25 U of Taq polymerase and 1 × MgCl 2 -free buffer (Promega), 2 mM MgCl 2 , 200 nM of each dNTP, appropriate oligonucleotides (1 μM each) and 5 ng of Crmyc2 cDNA in pGEM-T Easy (Promega).

Techniques: Sequencing

Figure Lengend Snippet: Alignment of amino acid sequences of CrMYC2, AtMYC2/RAP1/AtbHLH006/At1g32640.1, At4g17880.1, At5g46760.1, At5g46830.1 and Os10g42430.1 . Bold letters correspond to conserved amino acids residues within a putative NLS. Basic amino acids are boxed in grey. Asterisks under sequences correspond to positions where the amino acid is the same for all sequences. Boxed or underlined sequences indicate the three regions involved in CrMYC2 nuclear targeting.

Figure Lengend Snippet: Subcellular localization in epidermal onion cells of fusions of GFP with full-length CrMYC2, with different putative nuclear localization signals and with deletion mutants of CrMYC2 . The green fluorescence of the GFP protein was visualized by epifluorescence microscopy. A: control with GFP alone. B: control with GFP fused to the NLS of the SV40 large T antigen. C: control with GFP fused to an endoplasmic reticulum retention signal. D: right, GFP fused to full-length CrMYC2, left: corresponding DAPI staining,. E-H: GFP fused with different putative NLS sequences from CrMYC2, 1, 2, 3 and 4, respectively; I-P: GFP fused with different deletion mutants of CrMYC2 (F1 to F8).
