This review describes sources of structures of non-microspore origin observed in anther and microspore cultures. Various characteristics of these structures may cause a wrong diagnosis of these struct...
Potted rice plants were grown in the phytotron with different water temperatures in a range from 18 to 25°C during the period from the spikelet differentiation stage to just before the young microspor...
Cooling treatments at different stages of pollen development lowered the percentage of fertilized spikelets through decreasing the number of engorged pollen grains per anther at anthesis. Cooling duri...
We divided the developmental processes from microspore differentiation to fertilization into 4 phases and defined the component relating to fertilization in each phase. The percentage of fertilization...
Development of pollen cells as well as the fate of tapetal cells were studied by the glycol methacrylate semithin method for light microscopy. Sections including artificially produced images of pollen...
Cool Tolerance of Barley (Hordeum vulgare L.) at the Young Microspore Stage.
In vitro pollen germination experiment using agar plates showed that the growth under high nitrogen conditions enhanced the damage to pollen germination ability caused by the cooling at the young micr...
Changes in gene expression patterns by high nitrogen (High-N) and High-N plus cooling at the young microspore stage (High-N-cooling) in rice mature anthers were analyzed by semiquantitative RT-PCR wit...
Many field observations have suggested that roots play an important role in the tolerance to the sterillity-type cool-weather damage at booting stage in rice plants. However, how the roots affect fert...
The effects of gibberellin, cytokinin and an inhibitor of gibberellin biosynthesis on spikelet fertility and the number of pollen grains were examined in rice plants which were cooled at the young mic...
The relative amount of roots (dry weight ratio of root to shoot, or root dry weight per spikelet) or the physiological activity of roots is correlated with the cool-weather resistance in rice plants. ...
A selected set of twenty inter-line F 1 hybrids of Brassica napus L. was evaluated for their capacity to produce microspore-derived doubled haploid (DH) plants subsequently utilized in the breedi...
