Abstract:
... Two new PAM fluorometers (pulse amplitude modulated) were used in an investigation of photosynthetic performance of Prochloron resident as a symbiont in the ascidian C Lissoclinum patella, growing in a coral reef of Heron Island on the Great Barrier Reef. With a new DIVING- PAM in situ measurements of effective PSII quantum yield (deltaF/Fm') as a function of quantum flux density (rapid light curv ...

Abstract:
... To elucidate the involvement of brassinosteroids in the progression of tracheary element differentiation in cultured Zinnia cells, we analyzed the effects of uniconazole, an inhibitor of brassinosteroid synthesis, and brassinolide, a biologically active brassinosteroid, on the accumulation of mRNAs for various genes that were expressed in different stages of differentiation. Uniconazole specifical ...

Abstract:
... The shoot apical meristem functions to generate the lateral organs of a plant throughout the vegetative and reproductive phases. Homeobox genes play key roles in controlling such developmental programs, but their modes of action have not been well defined. Here we describe isolation and biological functions of a novel tobacco homeobox gene, designated NTH15 (Nicotiana tabacum homeobox 15), from a ...

Abstract:
... N-acetylchitooligosaccharides (fragments of chitin) elicit defense responses, including phytoalexin production, in suspension-cultured rice cells. They induced rapid and transient membrane depolarization accompanied by a transient increase in net Cl- -efflux. The membrane depolarization was not affected by anaerobiosis or azide, suggesting that the major part of the depolarization was mediated by ...

Abstract:
... Seedlings of Cuscuta japonica pasted on an acrylic plate developed many haustoria in response to far-red light after pre-irradiation with white light. The effect of far-red light was cancelled completely by red light irradiated immediately after the far-red light. In order to elucidate the photoreceptor(s) for photocontrol in the induction of haustoria, action spectra for the photo-induction and i ...

Abstract:
... Sensitive aequorin was microinjected into the cytoplasm of Nitella flexilis to study the role of Ca2+ in the generation of the tonoplast action potential. The temporal relation between the increase in cytoplasmic Ca2+ and the tonoplast action potential suggested that tonoplast action potential is triggered by an increase in cytoplasmic Ca2+. This is also supported by the fact that Mn2+, extracellu ...

Abstract:
... Properties of an unusual atp9-rpl16 cotranscript preferentially found in the maternal distorted leaf mutant of Arabidopsis thaliana, which had arisen from a genetic cross between chloroplast mutator and wild-type plants, were examined. Analysis of RNA editing of this cotranscript showed that one editing event in the rpl16 coding region created a UGA stop codon. This raises a possibility that a dow ...

Abstract:
... Tonoplast vesicles were prepared from the flesh tissue of mature pear fruit. Sugar uptakes into the vesicles determined by two different methods, the membrane and the gel filtration methods, were quite similar. The uptake was highest for glucose and subsequently, in order, for fructose, sucrose and sorbitol. It was not stimulated by addition of ATP, although the vesicles could create a proton grad ...

Northern analysis revealed the transcript of SoSPS1 to be predominant in leaves, but that of SoSPS2 to be distributed not only in leaves but also in roots at a similar level. The transcript of SoSPS1 was markedly accumulated during greening of etiolated leaves, where ...

The transcript le ...
