    Notes: Summary Arabinogalactan proteins (AGPs) are a class of plant extracellular-matrix proteins believed to participate in a broad range of processes involving the plant cell surface. They are extremely abundant in female reproductive tissues and in pollen tubes, the haploid male structures that traverse the diploid female reproductive tissues to deliver sperms to the egg cells. The prevalence of AGPs in reproductive tissues has led to speculations that they play significant functional roles ranging from serving as nutrient resources to cell-cell recognition in plant reproduction. Recent research from several laboratories demonstrated functional participation by AGPs in reproductive processes and began to examine the mechanisms underlying these functional roles. An overview of these recent studies will be discussed with a historical perspective as well as with a view towards future studies in establishing the significance of AGPs that, as a class, they have prominent roles in plant sexual reproduction in multiple and diverse ways.

    Notes: Abstract (E)-12-Tetradecenyl acetate (E12–14∶OAc), (Z)-12-tetradecenyl acetate (Z12–143nOAc), and tetradecanyl acetate (14∶OAc) were extracted and identified as major chemical components from female tips of the Asian corn borer,Ostrinia furnacalis (Hübner) (Lepidoptera: Pyralidae) in Taiwan, with a combined wash ratio of 48∶37∶15 and an individual female ratio of 45∶39∶16. The average amount ofE12-,Z12–14∶OAc and 14∶OAc in each female gland was 6.6±4.6, 5.8±3.5, and 2.4±1.7 ng/female, respectively. The mixture of these three synthetic chemicals not only gave strong activities in male antennae but also could catch significantly more males than virgin females in field-trapping tests. The field test also showed no significant difference in trapping ability among the three-component Taiwan formulations, the two-component Taiwan formulation (Z12–14∶OAc andZ1214∶OAc, 53∶47), and the Japan formulation (Z12–14∶ OAc andE 12–14∶OAc, 3:2).
