Apyrase and extracellular ATP play crucial roles in mediating plant growth defense responses. In the cold-tolerant poplar, Populus euphratica, low temperatures up-regulate APYRASE2 (PeAPY2) expression callus cells. We investigated biochemical characteristics of PeAPY2 its role cold tolerance. found that predominantly localized to plasma membrane, but punctate signals also appeared endoplasmic reticulum Golgi apparatus. exhibited broad substrate specificity, it most efficiently hydrolyzed...
Abstract Salt-induced fluxes of H+, Na+, K+, and Ca2+ were investigated in ectomycorrhizal (EM) associations formed by Paxillus involutus (strains MAJ NAU) with the salt-sensitive poplar hybrid Populus × canescens. A scanning ion-selective electrode technique was used to measure flux profiles non-EM roots axenically grown EM cultures two P. isolates identify whether major alterations detected promoted fungal partner. plants exhibited a more pronounced ability maintain K+/Na+ homeostasis...
Summary In higher plants, the salt overly sensitive ( SOS ) signalling pathway plays a crucial role in maintaining ion homoeostasis and conferring tolerance under salinity condition. Previously, we functionally characterized conserved woody plant Populus trichocarpa . this study, demonstrate that overexpression of constitutively active form Pt 2 TD ), one key components pathway, significantly increased aspen hybrid clone Shanxin Yang davidiana × bolleana ). Compared to wild‐type control,...
Abstract Screening for root traits has been one of the most difficult areas to practise over large number genotypes. Hydroponic systems enable easy access roots while high‐molecular weight polyethylene glycol ( PEG ) is used induce water stress. A total 838 genotypes were evaluated length in a hydroponic trial under ‐induced stress and non‐stress growing conditions. Augmented complete block design with seven blocks six standard control varieties was used. Root differences highly significant...
Salt stress is an important environmental cue impeding poplar nitrogen nutrition. Here, we characterized the impact of salinity on proton-driven nitrate fluxes in ectomycorrhizal roots and importance a Hartig net for uptake. We employed two Paxillus involutus strains root colonization: MAJ, which forms typical structures (mantle net), NAU, colonizing with thin, loose hyphal sheath. Fungus-colonized noncolonized Populus × canescens were exposed to sodium chloride used measure surface pH,...
Using 3-month-old seedlings of Bruguiera gymnorrhiza (L.) Savigny and Kandelia candel Druce, we compared species differences in ionic homeostasis control between the two non-secretor mangrove species. A high salinity (400 mM NaCl, 4 weeks) resulted a decline K+/Na+ ratio root leaf tissues, reduction was more pronounced K. (41–66%) as with B. (5–36%). Salt-altered flux profiles Na+, K+, H+ Ca2+ roots effects exogenous hydrogen peroxide (H2O2), nitric oxide (NO) on ion fluxes were examined...
Heat shock transcription factor (HSF) is an important TF that performs a dominant role in plant growth, development, and stress response network. In this study, we identified total of 30 HSF members from poplar, which are unevenly distributed on 17 chromosomes. The poplar family can be divided into three subfamilies, the same subfamily share relatively conserved domains motifs. acidic hydrophilic proteins located nucleus mainly carry out gene expansion through segmental replication....
Using a Non-invasive Micro-test Technique, flux profiles of Cd2+, Ca2+, and H+ were investigated in axenically grown cultures two strains Paxillus involutus (MAJ NAU), ectomycorrhizae formed by these fungi with the woody Cd2+-hyperaccumulator, Populus × canescens, non-mycorrhizal (NM) roots. The influx Cd2+ increased fungal mycelia, NM ectomycorrhizal (EM) roots upon 40-min shock, after short-term (ST, 24 h), or long term (LT, 7 d) exposure to hydroponic environment 50 uM CdCl2. treatments...
Histone deacetylases (HDACs) are key enzymes catalyzing the removal of acetyl groups from histones. HDACs act in concert with histone acetyltransferases (HATs) to regulate acetylation status, which modifies chromatin structure, affecting gene transcription and thus regulating multiple biological processes such as plant growth development. Over a decade, certain herbaceous plants have been deeply studied. However, functions woody not well understood. deacetylase specific inhibitor...
Abstract Three new pyrrole alkaloids albifipyrrols A–C ( 1–3 ), were isolated from the endophytic fungus Albifimbria viridis collected Chinese medicinal plant. Their structures elucidated by extensive NMR and HRESIMS spectrometric analyses. All compounds evaluated for immunosuppressive activity. Fortunately, compound 2 exhibits certain inhibition specifically against LPS-induced proliferation of B lymphocyte cells with IC 50 value 16.16 μM. Graphical
Thaumatin-like proteins (TLPs) in plants are involved diverse biotic and abiotic stresses, including antifungal activity, low temperature, drought, high salinity. However, the roles of
Water deficit caused by osmotic stress and drought limits crop yield tree growth worldwide. Screening identifying candidate genes from stress-resistant species are a genetic engineering strategy to increase resistance. In this study, an increased concentration of mannitol resulted in elevated expression thioredoxin f (KcTrxf) the nonsecretor mangrove Kandelia candel. By means amino acid sequence phylogenetic analysis, Trx was classified as f-type thioredoxin. Subcellular localization showed...
Cadmium (Cd2+) pollution occurring in salt-affected soils has become an increasing environmental concern the world. Fast-growing poplars have been widely utilized for phytoremediation of soil contaminating heavy metals (HMs). However, woody Cd2+-hyperaccumulator, Populus × canescens, is relatively salt-sensitive and therefore cannot be directly used to remediate HMs from soils. The aim present study was testify whether colonization P. canescens with ectomycorrhizal (EM) fungi, a strategy...
