A, Fructan accumulation in onion leaves. TLC of sugars extracted from onion leaves after several time intervals of continuous illumination and feeding of 5% Suc. F, Fru; G, Glc; S, Suc; N-K, neokestose; 1-K, 1-kestose; Nys, nystose; DP1-DP6, inulin fructan with a degree of polymerization of 1 to 6; O, sugar products of onion bulb; C, inulin from chicory. B, mRNA levels of 1-SST, invertase, and 6G-FFT during fructan accumulation in onion leaves. Northern blots contain approximately 20 μg of total RNA from onion leaves treated similarly as the ones used in A. cDNA clones encoding onion 1-SST, invertase, and 6G-FFT were used as probes. An Arabidopsis 18S rRNA probe was used as a loading control.
