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
Kimberly A. Novick, Alexandra G. Konings, Pierre Gentine
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 surpris...... hiện toàn bộ
Cryptochromes integrate green light signals into the circadian system
Plant, Cell and Environment - Tập 43 Số 1 - Trang 16-27 - 2020
Martin William Battle, Matthew A. Jones
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 enviro...... hiện toàn bộ
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
Leonid V. Kurepin, R. J. Neil Emery, Richard P. Pharis, David B. Dunger
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....... hiện toàn bộ
ALKBH9C, a potential RNA m6A demethylase, regulates the response of Arabidopsis to abiotic stresses and abscisic acid
Plant, Cell and Environment - Tập 45 Số 12 - Trang 3566-3581 - 2022
Umme Amara, Yasira Shoaib, Hunseung Kang
AbstractAlthough several studies have shown that AlkB homolog (ALKBH) proteins are potential RNA demethylases (referred to as ‘erasers’), biological functions of only a few ALKBH proteins have been characterized to date. In this study, we determined the function of ALKBH9C (At4g36090) in seed germination and seedling growth of Arabidopsis thaliana... hiện toàn bộ
Isolation of nuclear shells from plant cells
Plant, Cell and Environment - Tập 11 Số 9 - Trang 819-825 - 1988
Zoya Galcheva-Gargova, Emma M. Marinova, Stanka Koleva
Abstract. Nuclei from Zea mays and Phaseolus vulgaris root meristematic and differentiated cells were treated according to a recently developed simple procedure for isolation of nuclear lamina of Ehrlich Ascite Tumor (EAT) cells. As revealed by electron microscopy, the residual structures obtained represented empt...... hiện toàn bộ
Singlet oxygen and photo‐oxidative stress management in plants and algae
Plant, Cell and Environment - Tập 28 Số 8 - Trang 1037-1045 - 2005
Heidi Ledford, Krishna Niyogi
ABSTRACTPhotosynthetic organisms constantly face the threat of photo‐oxidative stress from fluctuating light conditions and environmental stress. Plants and algae have developed an array of defences to protect the chloroplast from reactive oxygen species. Genetic and physiological studies have shown that antioxidant responses are important to high‐light acclimation...... hiện toàn bộ
Convergence and divergence in gene expression profiles induced by leaf senescence and 27 senescence‐promoting hormonal, pathological and environmental stress treatments
Plant, Cell and Environment - Tập 35 Số 3 - Trang 644-655 - 2012
Yongfeng Guo, Susheng Gan
ABSTRACTIn addition to age and developmental progress, leaf senescence and senescence‐associated genes (SAGs) can be induced by other factors such as plant hormones, pathogen infection and environmental stresses. The relationship is not clear, however, between these induced senescence processes and developmental leaf senescence, and to wh...... hiện toàn bộ
Insights into the cellular mechanisms of desiccation tolerance among angiosperm resurrection plant species
Plant, Cell and Environment - Tập 27 Số 11 - Trang 1329-1340 - 2004
Maïté Vicré, Jill M. Farrant, Azeddine Driouich
ABSTRACTWater is a major limiting factor in growth and reproduction in plants. The ability of tissues to survive desiccation is commonly found in seeds or pollen but rarely present in vegetative tissues. Resurrection plants are remarkable as they can tolerate almost complete water loss from their vegetative tissues such as leaves and roots. Metabolism is shut down ...... hiện toàn bộ
The effect of drought and ultraviolet radiation on growth and stress markers in pea and wheat
Plant, Cell and Environment - Tập 24 Số 12 - Trang 1337-1344 - 2001
V. Alexieva, Iskren Sergiev, S. Mapelli, E. Karanov
AbstractIt emerged recently that there is an inter‐relationship between drought and ultraviolet‐B (UV‐B) radiation in plant responses, in that both stresses provoke an oxidative burst. The purpose of this investigation was to compare the effects and interaction of drought and UV‐B in wheat and pea. The absence of changes in relative leaf water content (RWC) after U...... hiện toàn bộ
The sucrose transporter HbSUT3 plays an active role in sucrose loading to laticifer and rubber productivity in exploited trees of Hevea brasiliensis (para rubber tree)
Plant, Cell and Environment - Tập 33 Số 10 - Trang 1708-1720 - 2010
Cheng‐Yi Tang, Debao Huang, Jen Tsi Yang, S.H. Liu, Soulaïman Sakr, He‐Ping Li, Yihua Zhou, Yunxia Qin
ABSTRACTEfficient sucrose loading in rubber‐producing cells (laticifer cells) is essential for retaining rubber productivity in Hevea brasiliensis, but the molecular mechanisms underlying the regulation of this process remain unknown. Here, we functionally characterized a putative Hevea SUT member, ...... hiện toàn bộ
