Abstract: The ability of the pregnant human cervix to produce prostanoids has been studied using an in vitro superfusion technique. Tissues obtained from four patients during the first trimester of pregnancy produced prostaglandin E (PGE), prostaglandin F (PGF), 13,14-dihydro-15-oxo-prostaglandin F (PGFM) and 6-oxo-prostaglandin F1 alpha (6-oxo-PGF1 alpha). Production of thromboxane B2 (TXB2) was minimal. Preliminary studies using tissue taken at Caesarean hysterectomy during the last trimester of pregnancy indicate that the cervix may show increased prostanoid production during active dilatation. The implications of these observations for an involvement of prostanoids in cervical softening during human parturition are discussed.

Abstract: Regeneration of fertile green plants from isolated oat microspores is reported for the first time. Factors critical for microspore growth and regeneration include cold pre-treatment, pH of culture medium and the use of conditioned culture medium. It was found that cold pre-treatment at 4 degrees C in the dark for a minimum of 6 weeks was necessary to consistently achieve microspore growth into multicellular structures (MCS). Longer pre-treatments of up to 9 weeks were tested and found to be positively correlated with the number of MCS produced. Microspore culture medium with pH 8.0 produced significantly more MCS larger than eight cells in size than media with pH 5.8. The use of medium conditioned by actively growing barley microspores significantly increased the numbers of MCS larger than eight cells in size compared to non-conditioned media. Plants were regenerated only from cultures using conditioned medium. A total of 2 green plants and 15 albinos were regenerated. Of the green plants, one had the haploid chromosome complement (n = 3x = 21) and the other had the parental hexaploid chromosome complement (2n = 6x = 42) which may be due to spontaneous chromosome doubling. The hexaploid plant set seed naturally and the haploid plant set seed after its chromosome complement was doubled with colchicine.

Abstract: Doubled haploid (DH) techniques using immature microspores or embryos rescued in vitro following interspecific hybridization are important tools for breeding wheat and barley and for generating populations for gene mapping purposes. Here, we describe methods being used for the successful production of spring wheat and barley DHs in Australia.

Abstract: Long-term (1940–1970) flowering synchrony of Eucalyptus leucoxylon ssp. pruinosa (F.Muell. ex Miq.) Boland, E. microcarpa (Maiden) Maiden, E. polyanthemos ssp. vestita L.A.S.Johnson & K.D.Hill and E. tricarpa (L.A.S.Johnson) L.A.S.Johnson & K.D.Hill was quantified at the tree level. The least synchronous grouping was E. polyanthemos and E. microcarpa (0.06), with flowering overlap occurring in only 5 of the 30 years. The species with the most synchronous flowering were E. leucoxylon and E. tricarpa (0.62): flowering overlapped in 24 of the 30 years. Synchrony in the 1996–1997 flowering season was found to be 'typical': overlap among all species pairs and groupings was within the range delineated by the long-term data (e.g. the synchrony of 0.53 for E. leucoxylon and E. polyanthemos was similar to its mean long-term overlap of 0.51). In idual species flowered synchronously, both within (0.82–0.92) and across sites (0.81– 0.93). Flowering did not occur in any of the monitored trees during 1997–1998. Long-term synchrony values assist in quantifying the likelihood of hybridisation between species, and provide a baseline which may assist in detecting recent or future changes.

Abstract: Doubled haploids (DHs) are an important tool for the accelerated production of new crop varieties. In oat, DHs were first produced by pollinating oat florets with maize pollen. The resultant embryos spontaneously eliminate the maize chromosomes leaving a haploid complement of oat chromosomes. These embryos can be cultured in vitro using the "embryo rescue" technique to produce haploid plants whose chromosome number can be doubled with colchicine to produce homozygous DH oat plants.
