Natural variation in E arly flowering1 contributes to early flowering in japonica rice under long days
Plant, Cell and Environment - Tập 37 Số 1 - Trang 101-112 - 2014
AbstractNatural variation in heading‐date genes enables rice, a short‐day (SD)
plant, to flower early under long‐day (LD) conditions at high latitudes. Through
analysis of heading‐date quantitative trait loci (QTL) with F7 recombinant
inbred lines from the cross of early heading ‘H143’ and late heading ‘Milyang23
(M23)’, we found a minor‐effect Early Heading3 (EH3) QTL in the Hd16 region on
chromo...
The intracellular ROS accumulation in elicitor‐induced immunity requires the multiple organelle‐targeted Arabidopsis NPK1 ‐related protein kinases
Plant, Cell and Environment - Tập 44 Số 3 - Trang 931-947 - 2021
AbstractRecognition at the plasma membrane of danger signals (elicitors)
belonging to the classes of the microbe/pathogen‐ and damage‐associated
molecular patterns is a key event in pathogen sensing by plants and is
associated with a rapid activation of immune responses. Different cellular
compartments, including plasma membrane, chloroplasts, nuclei and mitochondria,
are involved in the immune ce...
The Arabidopsis defensin gene AtPDF2.5 mediates cadmium tolerance and accumulation
Plant, Cell and Environment - Tập 42 Số 9 - Trang 2681-2695 - 2019
AbstractAlthough excess cadmium (Cd) accumulation is harmful to plants, the
molecular mechanisms underlying Cd detoxification and accumulation in
Arabidopsis thaliana remain largely undetermined. In this study, we demonstrated
that the A. thaliana PLANT DEFENSIN 2 gene AtPDF2.5 is involved in Cd tolerance
and accumulation. In vitro Cd‐binding assays revealed that AtPDF2.5 has
Cd‐chelating activity...
FIONA1‐mediated mRNA m6A methylation regulates the response of Arabidopsis to salt stress
Plant, Cell and Environment - - 2024
AbstractN6‐methyladenosine (m6A) is an mRNA modification widely found in
eukaryotes and plays a crucial role in plant development and stress responses.
FIONA1 (FIO1) is a recently identified m6A methyltransferase that regulates
Arabidopsis (Arabidopsis thaliana) floral transition; however, its role in
stress response remains unknown. In this study, we demonstrate that
FIO1‐mediated m6A methylation...
Beyond soil water potential: An expanded view on isohydricity including land–atmosphere interactions and phenology
Plant, Cell and Environment - Tập 42 Số 6 - Trang 1802-1815 - 2019
AbstractOver the past decade, the concept of isohydry or anisohydry, which
describes the link between soil water potential (ΨS), leaf water potential (ΨL),
and stomatal conductance (gs), has soared in popularity. However, its utility
has recently been questioned, and a surprising lack of coordination between the
dynamics of ΨL and gs across biomes has been reported. Here, we offer a more
expanded ...
Cryptochromes integrate green light signals into the circadian system
Plant, Cell and Environment - Tập 43 Số 1 - Trang 16-27 - 2020
AbstractPlants are acutely sensitive of their light environment, adapting their
growth habit and prioritizing developmental decisions to maximize fecundity. In
addition to providing an energy source and directional information, light
quality also contributes to entrainment of the circadian system, an endogenous
timing mechanism that integrates endogenous and environmental signalling cues to
promot...
The interaction of light quality and irradiance with gibberellins, cytokinins and auxin in regulating growth of Helianthus annuus hypocotyls
Plant, Cell and Environment - Tập 30 Số 2 - Trang 147-155 - 2007
ABSTRACTA reduced red to far‐red (R/FR) light ratio and low photosynthetically
active radiation (PAR) irradiance are both strong signals for inducing
etiolation growth of plant stems. Under natural field conditions, plants can be
exposed to either a reduced R/FR ratio or lower PAR, or to a combination of
both. We used Helianthus annuus L., the sunflower, to study the effect of
reduced R/FR ratio, ...
Physiological and molecular mechanisms of heavy metal accumulation in nonmycorrhizal versus mycorrhizal plants
Plant, Cell and Environment - Tập 42 Số 4 - Trang 1087-1103 - 2019
AbstractUptake, translocation, detoxification, and sequestration of heavy metals
(HMs) are key processes in plants to deal with excess amounts of HM. Under
natural conditions, plant roots often establish ecto‐ and/or
arbuscular‐mycorrhizae with their fungal partners, thereby altering HM
accumulation in host plants. This review considers the progress in understanding
the physiological and molecular...
Involvement of gibberellins in the stem elongation of sun and shade ecotypes of Stellaria longipes that is induced by low light irradiance
Plant, Cell and Environment - Tập 29 Số 7 - Trang 1319-1328 - 2006
ABSTRACTPlants from two ecotypes of Stellaria longipes, alpine (an open, sunny
habitat) and prairie (where adjacent plants provide a shaded habitat), were
grown under normal and reduced levels of photosynthetically active radiation
(PAR). Growth under low PAR is significantly promoted in both ecotypes. When
quantified by the stable isotope dilution method, endogenous gibberellins (GAs)
(GA1, GA8, ...
The shade‐avoidance syndrome: multiple signals and ecological consequences
Plant, Cell and Environment - Tập 40 Số 11 - Trang 2530-2543 - 2017
AbstractPlants use photoreceptor proteins to detect the proximity of other
plants and to activate adaptive responses. Of these photoreceptors, phytochrome
B (phyB), which is sensitive to changes in the red (R) to far‐red (FR) ratio of
sunlight, is the one that has been studied in greatest detail. The molecular
connections between the proximity signal (low R:FR) and a model physiological
response (...
