Stable Plastid Transformation in Nicotiana benthamiana
Journal of Plant Biology - Tập 52 - Trang 244-250 - 2009
Plastids from Nicotiana benthamiana were transformed with the vector for
dicistronic expression of two genes—aminoglycoside 3'-adenyltransferase (aadA)
and green fluorescent protein (gfp)—in the plastids of Nicotiana tabacum.
Transplastomic shoots exhibited green fluorescence under UV light.
Transformation efficiencies were similar between species. Although the border
sequence (trnI and trnA) for ...
Transgenic Rice Overexperessing a Tomato Mitochondrial Phosphate Transporter, SlMPT3;1, Promotes Phosphate Uptake and Increases Grain Yield
Journal of Plant Biology - Tập 61 - Trang 383-400 - 2018
Mitochondrial phosphate transporter plays an important regulatory role in
promoting the uptake and transport of phosphate in plants. In this study, the
SlMPT3;1 gene, a member of mitochondrial phosphate transporter family in tomato,
was isolated and transformed into the rice Oryza sativa L. ssp. japonica
cultivar Kitaake. The SlMPT3;1 is localized to the mitochondrial membrane and
functions in com...
ROS-Mediated ABA Signaling
Journal of Plant Biology - Tập 52 - Trang 102-113 - 2009
In plants, reactive oxygen species (ROS) are short-lived molecules produced
through various cellular mechanisms in response to biotic and abiotic stimuli.
ROS function as second messengers for hormone signaling, development, oxygen
deprivation, programmed cell death, and plant–pathogen interactions. Recent
research on ROS-mediated responses has produced stimulating findings such as the
specific so...
Cell type identity inArabidopsis roots is altered by both ascorbic acid-induced changes in the redox environment and the resultant endogenous auxin response
Journal of Plant Biology - Tập 50 - Trang 484-489 - 2007
Redox plays a critical role in controlling many cellular processes of plant
growth and development. To understand the effect of changes in redox on
cell-type determination in the root meristem, we examined the influence of a
strong reducing agent -ascorbic acid (AA) - on both the expression patterns of
several cell type-specific promoters and the endogenous auxin sensitivity of
auxin-responsive DR...
Sequence Variation and Comparison of the 5S rRNA Sequences in Allium Species and their Chromosomal Distribution in Four Allium Species
Journal of Plant Biology - Tập 55 - Trang 15-25 - 2011
The gene structure and sequence diversity of 5S rRNA genes were analyzed in 13
Allium species. While the lengths and sequences of the coding gene segments were
conserved, the spacers were highly variable and could be characterized as either
short (213–404 bp) or long (384–486 bp) spacers. The short spacers were further
classified into five subtypes (SS-I to SS-V) and the long spacers into four
sub...
Castasterone Can be Biosynthesized from 28-homodolichosterone in Arabidopsis thaliana
Journal of Plant Biology - Tập 61 - Trang 330-335 - 2018
We recently demonstrated the biosynthesis of 24-ethylidene brassinosteroids in
Arabidopsis thaliana. To determine the physiological role of biosynthesis of
24-ethylidene brassinosteroids, metabolism of 28-homodolichosterone as the end
product of 24-ethylidene brassinosteroids biosynthesis was examined by a crude
enzyme solution prepared from A. thaliana. In wild-type plants, dolichosterone
and cas...
Phosphorus use efficiency in anthocyanin-free tomato (Lycopersicon esculentum Mill.)
Journal of Plant Biology - Tập 41 - Trang 86-92 - 1998
An anthocyanin-free tomato plant, H957, and its parental wild type, H883, were
hydroponically grown to test for tolerance to a low phosphorus (P) in H957. The
tolerance was evaluated by comparing growth and metabolism of H957 vs. H883 at
different P concentrations ranging 25–400 μM. Fresh weights were measured
weekly. Dry weight, mineral contents, photosynthetic rate, and P utilization
ratios of t...
Reactive oxygen species mediate IAA-lnduced ethylene production in mungbean (Vigna radiata L.) hypocotyls
Journal of Plant Biology - Tập 50 - Trang 18-23 - 2007
We reported previously that ROS may function as a downstream component for
signaling auxin, a hormone that induces the ethylene production. Here we
demonstrated that ROS can act upstream to promote auxin-induced ethylene
production in mungbean hypocotyls. When plants were treated with AVG, ethyiene
biosynthetic inhibitor, or ACC, ethylene precursor, we found that little effect
on the ROS generatio...
Ultrastructural changes of cell organelles inArabidopsis stems after gamma irradation
Journal of Plant Biology - Tập 48 - Trang 195-200 - 2005
We examined ultrastructural changes of the cell organelles ofArabidopsis stems
in response to gamma irradiation. Seedlings treated with 0 to 5 Gy developed
normally, while height growth in plants exposed to 50 Gy was significantly
inhibited. Based on TEM observations, the chloroplasts were extremely sensitive
to such irradiation. In particular, the thylakoids were heavily swollen, some
portions of...
