Spikelet proteins expressed at the young microspore stage in rice were separated and analysed by two-dimensional polyacrylamide gel electrophoresis (2DE). The separated proteins were electro blotted onto a polyvinylidene difluoride (PVDF) membrane, and 50 proteins were analyzed by a gas-phase protein sequencer. The N-terminal amino acid sequences of 20 out of 50 proteins were determined. N-terminal regions of the remaining proteins could not be sequenced because of blocking. The internal amino acid sequences of proteins were determined by sequence analysis of peptides obtained by the Cleveland peptide mapping method. Results revealed the presence of the photosynthetic apparatus at rice young microspore stage. Major proteins identified in this study could be used as a marker for various studies on physiological stresses.

The lateral root formation in soybean sprout culture declines its quality. This study was done to measure the effect of fluorescent light treatment during 24 hour imbibition and 6-day culture on seed germination and growth of soybean sprout. After 6 day culture, the sprouts were sorted as normal (＞4cm), abnormal (＜4cm) and non-germination by their hypocotyl lengths, and lateral roots, fresh and dry weights were measured. Lateral roots were less formed in the fluorescent light treatment lasted during the whole period of the imbibition than in the treatment for 50 minutes a day during the culture. The fluorescent light treatment during the imbibition mainly affected the germination and growth compared to the treatment done during the culture. Compared to the dark imbibition, the light treatment during the imbibition resulted in more normal sprouts, thicker diameters of hypocotyl and hook, and more fresh weights in cotyledon, hypocotyl, whole sprout, and economic yield. However, these results were reverse in lengths of hypocotyl and root, and fresh and dry weights of roots. It is concluded that the fluorescent lamp mainly irradiating red and blue lights can be used for the sprout production as an alternative light replacing blue and red lights treated during the imbibition because it blocked the lateral root appearance and stimulated growth of the sprout.
