Abstract:
... Rice (Oryza sativa L.) is a typical Si-accumulating plant and is able to accumulate Si up to >10 % of shoot dry weight. The cell wall has been reported to become thicker under Si-deficient condition. To clarify the relationship between Si accumulation and cell wall components, the physical properties of, and macromolecular components and Si content in, the pectic, hemicellulosic, and cellulosic fr ...

Subject:
Turnera; autopolyploidy; diploidy; evolution; microspores; pollen
Abstract:
... Turnera sidoides is a complex of distylous perennial rhizomatous herbs that includes five subspecies. Since polyploidy has played a prominent role within this species (x = 7), ongoing studies in T. sidoides are focused on the understanding of the mechanisms involved in the origin and the establishment of polyploids. Therefore, aiming to contribute to the understanding of the mode of polyploid form ...

Abstract:
... Although an important oil crop, peanut has only 162,030 expressed sequence tags (ESTs) publicly available, 86,943 of which are from cultivated plants. More ESTs from cultivated peanuts are needed for isolation of stress-resistant, tissue-specific and developmentally important genes. Here, we generated 63,234 ESTs from our 5 constructed peanut cDNA libraries of Ralstonia solanacearum challenged roo ...

ISSN:

Subject:
acidification; bromoxynil; plasma membrane; proton pump; protons
Abstract:
... In the previous paper, I reported that 3,5-dibromo-4-hydroxybenzonitrile (bromoxynil) depolarizes the plasma membrane by inhibiting the electrogenic proton pump and discussed that the inhibition is caused by cytosol acidification due to influx of protonated bromoxynil and following release of proton (Shimmen in J Plant Res 123:715–722, 2010). However, a possibility of direct inhibition of the prot ...

Abstract:
... Range-wide genetic variation of Korean pine (Pinus koraiensis) was assessed using maternally inherited mtDNA and paternally inherited cpDNA for 16 natural populations throughout northeast Asia in order to study its phylogeographical history during the Quaternary. The cpDNA variation indicated that there was no difference between populations on the Asian continent and those in the Japanese archipel ...

Subject:
Dinophyceae; carotenoids; genes; nucleotide sequences; phylogeny; pigments; plastids; ribosomal RNA
Abstract:
... Green-colored plastids in the dinoflagellates Lepidodinium chlorophorum and L. viride have been widely believed as the remnant of an endosymbiotic prasinophyte. This hypothesis for the origin of the Lepidodinium plastids is solely based on an unpublished result quoted in Elbrächter and Schnepf (Phycologia 35:381–393, 1996) hinting at the presence of a characteristic carotenoid in prasinophytes, pr ...

Abstract:
... Pyridine compounds, including nicotinic acid and nicotinamide, are key metabolites of both the salvage pathway for NAD and the biosynthesis of related secondary compounds. We examined the in situ metabolic fate of [carbonyl-14C]nicotinamide, [2-14C]nicotinic acid and [carboxyl-14C]nicotinic acid riboside in tissue segments of tea (Camellia sinensis) plants, and determined the activity of enzymes i ...

Subject:
Arabidopsis thaliana; air temperature; flowering; gene expression; gene expression regulation; genes; microRNA; models; phenology; photoperiod; transcription (genetics)
Abstract:
... Plants monitor environmental factors, such as temperature and day length, and also endogenous factors, such as their age and phytohormones, to decide when to flower. These cues are utilized to control expression levels of genes required for flowering. Thus, flowering time control is a unique model for understanding how gene activity is precisely regulated at the transcriptional level. In Arabidops ...

DNA; EDTA (chelating agent); Taraxacum officinale; buffers; ethanol; filters; glass; plant tissues; polymerase chain reaction; sucrose
Abstract:
... For some plant species, DNA extraction and downstream experiments are inhibited by various chemicals such as polysaccharides and polyphenols. This short communication proposed an organic-solvent free (except for ethanol) extraction method. This method consists of an initial washing step with STE buffer (0.25 M sucrose, 0.03 M Tris, 0.05 M EDTA), followed by DNA extraction using a piece of glass fi ...

Abstract:
... Contrary to extensive researches on the roles of metallothioneins (MTs) in metal tolerance of animals, the roles of plant MTs in metal tolerance are largely under investigation. In this study, we evaluated the functional role of type 2 MT from Colocasia esculenta (CeMT2b) in Zn tolerance of tobacco and E. coli cells. Under Zn-stress conditions, transgenic tobacco overexpressing CeMT2b displayed mu ...
