Accumulation of LOX and icl
transcripts during in vitro senescence of cucumber cotyledons.
Cotyledons were excised from cucumber seedlings grown for 10 d
under a 14-h light/10-h dark photoperiod and then kept in the dark for
the number of days indicated. Total RNA (20 μg) isolated from the
cotyledons was loaded in each lane, separated with a denaturing gel,
transferred to a nylon membrane, and then sequentially probed with the
lox-1 3′ probe (A), the lox-1 internal
probe (B), and the icl probe (C).
