Expression of the TPE4A gene in
different tissues of the pea plant. Northern-blot analysis showing the
accumulation of the TPE4A transcript in leaves. Lane 1,
Young leaves; lane 2, mature leaves; lane 3, senescent leaves; lane A,
apex; lane S, stem; lane T, tendrils; lane R, roots. Petal lanes are as
follows: dā1, 1 d before anthesis; d 0, day of anthesis; and d+1,
1 d after anthesis, when the petals were senescent.
