To study similar, but distinct, plant disease resistance (R) specificities exhibited by allelic genes at the rice blast resistance locus Pik/Pikm, we cloned the Pik gene from rice cultivar Kanto51 and compared its molecular features with those of Pikm and of another Pik gene cloned from cv. Kusabue. Like Pikm, Pik is composed of two adjacent NBS-LRR(More)
1. To examine whether cytosolic Ca2+ in smooth muscle cells distributes evenly, cytosolic Ca2+ levels were measured with two different Ca2+ indicators in the ferret isolated portal vein; a fluorescent indicator, fura-PE3, that shows the average Ca2+ level, and a photoprotein, aequorin, that preferentially shows a high Ca2+ compartment. 2. A noradrenaline(More)
Exposing plants to hypoxic conditions greatly improves their anoxic stress tolerance by enhancing the activities of glycolysis and fermentation in roots. Ethylene may also be involved in these adaptive responses because its synthesis is increased in roots under hypoxic conditions. Here it is reported that pre-treatment of wheat seedlings with an ethylene(More)
— This paper describes the architecture (circuit design) and principles of operation of sigma-delta (ΣΔ) time-to-digital converters (TDC) for high-speed I/O interface circuit test applications; they offer good accuracy with short test times. In particular, we describe multi-bit ΣΔ TDC architectures for fast testing. However, mismatches among delay cells in(More)
Seed dormancy is an important agronomic trait: low levels can cause premature germination, while too much can inhibit uniform germination. As an approach to controlling the seed dormancy level in crops, we used Triticeae DOG1-like genes as transgenes. DOG1 is an Arabidopsis gene that underlies natural variation in seed dormancy. We previously showed that(More)
— This paper describes a method of generating low-distortion sinusoidal waves using an arbitrary waveform generator (AWG), and experimental results of using such a generator for ADC dynamic performance testing. With this proposed method, 3 rd order harmonics of the generated signal are suppressed simply by changing the AWG program (or waveform memory(More)

Effects of selective applications of drugs to the guinea pig hypogastric ganglion were studied on the contractile response of the vas deferens to the hypogastric nerve stimulation or to ganglionic stimulating drugs. Both acetylcholine (ACh) and dimethylphenylpiperazinium (DMPP) contracted the vas deferens. Neostigmine potentiated the ACh-induced(More)
