Young poplar plants were exposed to different heat regimes, a rapid heat constraint at 42°C (heat shock HS) alone or preceded by a stepwise increase in temperature (heat gradient HG). Proteomics analyses were carried out on both leaf and cambial tissues. The responses of both tissues were compared and linked to morphological and physiological observations. Both heat treatments negatively affected the photosynthetic rate while increasing the stomatal conductance. In the leaf, the HS impacted… Expand
Transcriptome analysis of heat stress response in switchgrass (Panicum virgatum L.)
TLDR
Gene ontology (GOs) enrichment analysis showed that genes related to ATPase regulator, chaperone binding, and protein folding was significantly up-regulated and GOs associated with protein modification, transcription, phosphorus and nitrogen metabolic processes, were significantly down-regulated by heat stress.

Proteomic analysis of common bean stem under drought stress using in-gel stable isotope labeling.
TLDR
Results reveal the complexity of pathways involved in the drought stress response in common bean stems and enable comparison with the results of proteomic analysis of leaves, thus providing important information to further understand the biochemical and molecular mechanisms of drought response in this important legume.

Proteomic Analysis of Kiwifruit in Response to the Postharvest Pathogen, Botrytis cinerea
TLDR
Virus-induced gene silencing was used to examine the role of myosin 10 in kiwifruit, a gene modulating host penetration resistance to fungal infection, in response to B. cinerea infection. Expand
Sugar Transporters in Plants: New Insights and Discoveries
TLDR
This review highlights recent findings that address the path of phloem loading of sucrose in rice and maize leaves, shed light on how plant pathogens hijack sugar transporters to obtain carbohydrates for pathogen survival, and how the plant employs sugar transportters to defend against pathogens. Expand
Heat stress affects the cytoskeleton and the delivery of sucrose synthase in tobacco pollen tubes
TLDR
It is shown that heat stress affects pollen germination and, to a lesser extent, pollen tube growth, and damage induced by heat stress also extends to proteins that bind actin and participate in cell wall synthesis, such as sucrose synthase. Expand
Expression Pattern and Promoter Analysis of a Eucalyptus grandis Germin-like Gene
TLDR
It is shown that the activity of the EgGLP promoter in tobacco is modulated by light/dark transition and is closely related to GLPs known to be regulated by the circadian rhythm. Expand
Combined Proteomic and Metabolomic Profiling of the Arabidopsis thaliana vps29 Mutant Reveals Pleiotropic Functions of the Retromer in Seed Development
TLDR
This study suggests that loss of the retromer stimulates energy metabolism, affects many metabolic pathways, including that of cell wall biogenesis, and triggers an osmotic stress response, underlining the importance ofretromer function in seed biology. Expand
In planta validation of HK1 homodimerization and recruitment of preferential HPt downstream partners involved in poplar multistep phosphorelay systems
TLDR
This work confirmed in planta homodimerization of the cytoplasmic part of HK1 (HK1-CP) and the functional relevance of HK 1-CP/HPt interactions by bimolecular fluorescence complementation assays and proposed them as probably involved in osmosensing pathway in Populus. Expand

Proteins responding to drought and high-temperature stress in Populus × euramericana cv. ‘74/76’
TLDR
The level of the photosynthesis proteins affected greatly by the imposed stress conditions was consistent with the observed noticeable decrease in net photosynthesis rate, providing a fundamental data for future research on responses to drought and high temperature, two major factors limiting the growth of forest trees during summer under recent climatic warming. Expand
Drought tolerance of two black poplar (Populus nigra L.) clones: contribution of carbohydrates and oxidative stress defence.
TLDR
Data suggest that assimilation and partitioning of carbon to the roots are decreased, resulting in mobilization of stored starch in Populus nigra plants, leading to a higher capacity to defend against oxidative stress. Expand
Responses of poplar to chilling temperatures: proteomic and physiological aspects.
TLDR
Cold exposure induced a decrease in the candidate proteins involved in cell wall or energy production, especially in dehydrins and other late embryogenesis abundant proteins. Expand
Poplar under drought: comparison of leaf and cambial proteomic responses.
TLDR
There is a difference in the moment of response to the water constraint between the two tissues, cambium being affected later than leaves, and a significant number of leaf proteins appeared to be differentially regulated only during the recovery from drought. Expand
Root proteomic responses to heat stress in two Agrostis grass species contrasting in heat tolerance
TLDR
Phosphoproteomic analysis indicated that two isoforms of fructose-biphosphate aldolase were highly phosphorylated under heat stress, and thermal A. scabra roots had more up-regulated proteins than A. stolonifera roots, suggesting that the a Aldolase phosphorylation might be involved in root thermotolerance.

Proteomic and enzymatic response of poplar to cadmium stress.
TLDR
Proteomic and enzymatic changes in roots and leaves of actively growing poplar plants upon a cadmium stress exposure are highlighted and it appeared that the metabolic impact of Cadmium was more deleterious than in leaves. Expand
Ascorbate Peroxidase 1 Plays a Key Role in the Response of Arabidopsis thaliana to Stress Combination*
TLDR
Proteomic and metabolic analysis of Arabidopsis thaliana plants subjected to a combination of drought and heat stress suggests that cytosolic APX1 plays a key role in the acclimation of plants to aCombined drought andHeat stress. Expand
Physiological and proteomic responses of two contrasting Populus cathayana populations to drought stress.
TLDR
The results suggest that poplars' tolerance to drought stress relates to the control of reactive oxygen species (ROS) and to osmoprotective capacity and the differential regulation of some drought-responsive proteins, such as HSPs and the enzymes related to redox homeostasis and regulation of secondary metabolism, plays an important role in Populus cathayana Rehder's tolerance and acclimation to drought Stress.

Non-redundant functions of sHSP-CIs in acquired thermotolerance and their role in early seed development in Arabidopsis
TLDR
It is shown that the rose (Rosa hybrida) cytoplasmic 17.5-kDa Class I small HSP increases dramatically during flower development, and accumulates in closed bud petals and leaves only in response to heat stress, and analysis of Arabidopsis T-DNA insertion lines affected at three homologous genes revealed that their acquired thermotolerance is impaired.

Use of expression analysis to dissect alterations in carbohydrate metabolism in wheat leaves during drought stress
TLDR
Systematic expression analysis of an almost complete set of genes involved in conversion of triose phosphates to hexoses and hexose phosphorylation showed that isoenzymes of many enzymes were differentially regulated during drought stress, and coordinated down-regulation of drought down-regulated Calvin cycle genes was indicated.
