Development of a Precise Polarization Modulator for UV Spectropolarimetry
We developed a polarization modulation unit (PMU) to rotate a waveplate continuously in order to observe solar magnetic fields by spectropolarimetry. The non-uniformity of the PMU rotation may cause errors in ...

Analysis of the duplicated CHS1 gene related to the suppression of the seed coat pigmentation in yellow soybeans
Seed coat color in soybean is controlled by the classically defined I (Inhibitor) locus. The seeds of most commercial soybean varieties are yellow due to the presence of a dominant allele of the I locus (I: yello...
