The Arabidopsis thaliana NAC domain transcription factor, VASCULAR-RELATED NAC-DOMAIN7 (VND7), acts as a key regulator of xylem vessel differentiation. In order to identify direct target genes of VND7, we performed global transcriptome analysis using Arabidopsis transgenic lines in which VND7 activity could be induced post-translationally. This analysis(More)
To express a foreign gene in plants effectively, a good expression system is required. Here we describe the identification of a transcriptional terminator that supports increased levels of expression. The terminators of several Arabidopsis genes were examined in transfected Arabidopsis T87 protoplasts. The heat shock protein 18.2 (HSP) terminator was the(More)
PURPOSE Recent studies have shown that low-intensity resistance training with vascular occlusion (kaatsu training) induces muscle hypertrophy. A local hypoxic environment facilitates muscle hypertrophy during kaatsu training. We postulated that muscle hypertrophy can be more efficiently induced by placing the entire body in a hypoxic environment to induce(More)
Eubacterial-type multi-subunit plastid RNA polymerase (PEP) is responsible for the principal transcription activity in chloroplasts. PEP is composed of plastid-encoded core subunits and one of multiple nuclear-encoded sigma factors that confer promoter specificity on PEP. Thus, the replacement of sigma factors associated with PEP has been assumed to be a(More)
Although the active digestion of mating-type minus (mt-) chloroplast DNA (cpDNA) in young zygotes is considered to be the basis for the uniparental inheritance of cpDNA in Chlamydomonas reinhardtii, little is known about the underlying molecular mechanism. One model of active digestion proposes that nucleases are either synthesized or activated to digest(More)
The alcohol dehydrogenase gene (NtADH) was previously isolated from tobacco BY2 suspension cultured cell. Expression of this gene was dramatically increased only during the early stationary phase, and the 5'-untranslated region (5'-UTR) was hypothesized to be involved in the stimulatory effect at the post-transcriptional level. In this paper, we(More)
An exogenous gene, placed between the 5'-upstream regions of the Chlamydomonas reinhardtii chloroplast genes, rbcL or psbA, and the 3'-end of the rbcL gene, do not have the same expression pattern as endogenous genes in the C. reinhardtii chloroplast. Here, we chose four chloroplast genes, rbcL, psbA, psbD and atpA, and examine the effects of chloroplast(More)
(R)-4-Chloro-3-hydroxybutyrate (CHB) and (S)-3-hydroxy-gamma-butyrolactone (HL) are used for the synthesis of biologically and pharmacologically important compounds. Enterobacter sp. DS-S-75 was found to have the unique activity to convert (S)-CHB in the racemate to (S)-HL through asymmetric dechlorination, hydrolysis, and lactonization. As a result, the(More)
Abiotic stress influences the translation of mRNAs in plants. To gain a global view of the early translational response to abiotic stress, we investigated genome-wide changes in mRNA translation in Arabidopsis thaliana suspension cell cultures exposed to brief periods of two types of stress: elevated temperature (37 degrees C) and high salinity (200 mM(More)
The 5'-untranslated region (5'-UTR) functions as a translational enhancer in monocotyledonous plant cells is necessary to express a foreign gene efficiently. Here, we show that the 5'-UTR of the rice alcohol dehydrogenase gene contributes to efficient translation in not only dicotyledonous plant cells, but also in monocotyledonous rice cells.
