material for RNA isolation, cDNA and RT-PCR
- harvest ~50 mg of leaves, petioles, flowers, stem, roots from 58d.o. medicago truncatula A17 plant (4 biological repeats each) → freeze in liquid nitrogen
- RNA isolation following Qiagen protocol; quantities:
petiole 1: 352 ng/μL
petiole 2: 446 ng/μL
petiole 3: 1703 ng/μL
petiole 4: 402 ng/μL
stem 1: 154 ng/μL
stem 2: 834 ng/μL
stem 3: 418 ng/μL
root 1: 405 ng/μL
root 2: 540 ng/μL
root 3: 468 ng/μL
root 4: 693 ng/μL
leaves 1: 2335 ng/μL
leaves 2: 2116 ng/μL
leaves 3: 1326 ng/μL
leaves 4: 291 ng/μL
flowers 1: 2591 ng/μL
→ store in -80°C
- cDNA synthesis using supersript III following manufacturer's protocol; at first only one sample of each tissue → use 2 µg RNA of petiole 2, stem 2, root 4, leaves 2, flowers 1
→ store in -20°C
