Aim To analyse the cytomorphological features of kerati- nocytes in smears obtained from the oral mucosa of tobacco users and from oral squamous cell carcinoma lesions. Methodology Oral smears were obtained from clinically, normal appearing mucosa of oral squamous cell carcinoma patients （n=20） and from the mucosa of smokers （n=20）, and apparently healthy individuals （n=20） were used as controls. The smears were histochemically stained and cytomorphological assessment of the keratinocytes was carried out. One-way ANOVA （Analysis of Variance） was used for comparing the parameters among multiple groups and Tukey-HSD test was used to compare the mean values between groups. Results The mean nuclear area of keratinocytes from the mucosa of tobacco users was 46 ± 2.57 and that of the oral squamous cell carcinoma lesion was 81.54±4.31. While there was a significant （P=0.001） reduction in the cellular area of keratinocytes from oral squamous cell carcinoma lesion when compared with those from oral smears of tobacco users. Conclusion Cytomorphometric analysis of keratinocytes can serve as a useful adjunct in the early diagnosis of oral squamous cell carcinomas.

Using RNAi, the seed oil body protein 24-kDa oleosin has been suppressed in transgenic soybeans. The endoplasmic reticulum （ER） forms micro-oil bodies about 50 nm in diameter that coalesce with adjacent oil bodies forming a hierarchy of oil body sizes. The oil bodies in the oleosin knockdown form large oil body-ER complexes with the interior dominated by micro-oil bodies and intermediate-sized oil bodies, while the peripheral areas of the complex are dominated by large oil bodies. The complex merges to form giant oil bodies with onset of seed dormancy that disrupts cell structure. The transcriptome of the oleosin knockdown shows few changes compared to wild-type. Proteomic analysis of the isolated oil bodies of the 24-kDa oleosin knockdown shows the absence of the 24-kDa oleosin and the presence of abundant caleosin and lipoxygenase. The formation of the micro-oil bodies in the oleosin knockdown is interpreted to indicate a function of the oleosin as a surfactant.

Double fertilization in flowering plants occurs when the two sperm cells, carried by the pollen tube, are released in a synergid cell of the embryo sac and then fertilize the egg and the central cell. Proteins on the surfaces of the sperm, egg, central, and synergid cells might be important for guidance and recognition/fusion of the gametes. Here, we present functional analyses ofArabidopsis GEX3, which encodes a plasma membrane-localized protein that has homologs in other plants. GEX3 is expressed in both the vegetative and sperm cells of the male gametophyte and in the egg cell of the female gametophyte. Transgenic lines in which GEX3 was down-regulated or overexpressed, using the Arabidopsis GEX2 promoter, had reduced seed set. Reciprocal crosses and imaging after pollination with a reporter line showed that, in both cases, the defect causing reduced seed set occurred in the female. In the antisense lines, micropylar pollen tube guidance failed, In the overexpression lines, fertilization of mutant ovules was mostly blocked because pollen tube guidance failed, although, occasionally, non-viable embryos were formed. We conclude that properly regulated expression of GEX3 in the egg cell of Arabidopsis is essential for pollen tube guidance.
