    Notes: Abstract  DNA polymorphism between a cytoplasmic male-sterile rice line II-32A, the male-fertile maintainer counterpart II-32B, a fertile revertant (T24), as well as two commercial indica restorers, was analyzed with randomly amplified polymorphic DNA (RAPD). A very low degree of polymorphism was found between the revertant T24 and II-32A compared with that of indica rice varieties. This result, together with agronomic and genetic evidence, suggests the revertant to be a product of a nuclear mutation. An analysis of polymorphism between II-32A and the revertant T24 with 510 RAPD decamer primers identified the co-segregating markers OPB07640 and OPB181000 to be linked to a sterile allele of the restoring locus in the revertant T24, at a distance of 5.3 cM. RAPD analysis of a mapping population of Tesanai2/CB with primer OPB07 revealed linkage of OPB07640 with RG374 (10.8 cM) and RG394 (8.8 cM) on chromosome 1. Thus the restorer gene, designated Rf 5, was tentatively localized between RG374 and RG394 on chromosome 1 and appears to be independent of other mapped restorer genes in rice.

    Notes: Summary The efficiency (plate number per unit time) and elution power (range ofn-alkanes) of packed capillary SFC and SGC using CO2 as the mobile phase were compared. A higher plate number per unit time was obtained in SGC than in SFC using the same column under the same applied conditions. SGC is more suitable for fast separations than SFC. The solvating ability of the mobile phase, at the column exit end, decreased remarkably after the restrictor was removed. However, the elution molecular weight range in SGC can be greatly extended by increasing the column temperature.n-Alkanes with carbon numbers as high as 80 were separated under SGC conditions using a 35 cm ×250 μm i.d. column packed with 10 μm polymer-encapsulated silica particles at 200 atm, with a temperature program of 100–380°C at 10°C min−1.
