Organ specific expression of the cab gene in the above ground parts of sugar beet during development. RNA from root, lateral root, hypocotyl, cotyledon, petiole, sink and source leaf of sugar beets grown in the field was isolated 4, 6, 10, 12 16 and 19 weeks after sowing. Ten micrograms total RNA were separated in each lane and hybridized with the SSH fragment L2 (Table 1). The RNA gels were stained prior to blotting to confirm equal loading (data not shown).
