Common smut on 10 different varieties of maize,which caused by the fungus Ustilago maydis,was investigated under natural conditions in Shenyang in summer of 2004.

Both indoor and field tests showed that 12 5% diniconazole W P was a very good funggicides to control fungus Ustilago maydis Granule, a mixture of diniconazole and phoxim, could respectively provide 75 7% and 85% control efficiency to Ustilago maydis and Ostrinia Furanncalis if used before tasse

0 and potential GPI-anchor sites prediction algorithm Big-PI Predictor were employed to predict the subcellular location of proteins encoded in Ustilago maydis genome.

7 Mb of publicly available DNA sequence in Ustilago maydis was researched for mono- to hexanucleotide simple sequence repeat (SSR or microsatellite) to determine the type, size and frequency.

The application of black corn flour in bread production was studied The result indicated that bread quality was reduced to different degrees, with increased amount of black corn flour and decreased grain size The addition of black corn flour for 50, 70 and 90 meshes could not surpass 8%, 7% and 7% of flour weight respectively

The results showed that having black corn flour mixed with wheat flour in a proportion of 3.
