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
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 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
OsNRAMP1 transporter contributes to cadmium and manganese uptake in rice
Plant, Cell and Environment - Tập 43 Số 10 - Trang 2476-2491 - 2020
Jia‐Dong Chang, Sheng Huang, Naoki Yamaji, Wenwen Zhang, Jian Feng, Fang‐Jie Zhao
AbstractRice is a major dietary source of the toxic metal, cadmium (Cd). Previous studies reported that the rice transporter, OsNRAMP1, (Natural resistance‐associated macrophage protein 1) could transport iron (Fe), Cd and arsenic (As) in heterologous yeast assays. However, the in planta function of OsNRAMP1 remains unknown. Here, we show...... hiện toàn bộ
Dissecting the response to dehydration and salt (NaCl) in the resurrection plant Craterostigma plantagineum
Plant, Cell and Environment - Tập 26 Số 8 - Trang 1307-1315 - 2003
Claudia Smith‐Espinoza, Andreas Richter, F. Salamini, Dorothea Bartels
ABSTRACTAlthough desiccation tolerant, the resurrection plant Craterostigma plantagineum is sensitive to relatively low levels of sodium chloride. Exposure to sodium chloride, but not dehydration, led to accumulation of sodium ions in leaves and roots and caused irreversible wilting. The effects of salt and dehydration on transcript accum...... hiện toàn bộ
Nitrogen isotope composition of tomato (Lycopersicon esculentumMill. cv. T‐5) grown under ammonium or nitrate nutrition
Plant, Cell and Environment - Tập 19 Số 11 - Trang 1317-1323 - 1996
R. Evans, Arnold J. Bloom, Scott S. Sukrapanna, James R. Ehleringer
ABSTRACTStudies that quantify plant δ15N often assume that fractionation during nitrogen uptake and intra‐plant variation in δ15N are minimal. We tested both assumptions by growing tomato (Lycopersicon esculetumMill. cv. T‐5) at NH4+or NO−... hiện toàn bộ
