Trichoderma species are soil-borne filamentous fungi widely utilized for their many plant health benefits, such as conferring improved growth, disease resistance and abiotic stress tolerance to hosts. Many able produce the auxin phytohormone indole-3-acetic acid (IAA), its production has been suggested promote root growth. Here we show that of IAA is strain dependent diverse external stimuli associated with production. In in vitro assays, Arabidopsis primary length was negatively affected by...
Trichoderma spp colonizes the plant rhizosphere and provides pathogen resistance, abiotic stress tolerance, enhance growth development. We evaluated Arabidopsis-Trichoderma interaction using a split system in which atroviride virens were grown on PDA or MS medium. Arabidopsis was significantly increased at 3 5 days post-inoculation with both species, when fungal strains interaction. The analysis of DR5:uidA reporter line revealed greater auxin accumulation root tips fungi hair-defective...
Recent reports have underlined the potential of gamma ( γ )-rays as tools for seed priming, a process used in industry to increase vigor and enhance plant tolerance biotic/abiotic stresses. However, impact -rays on key aspects metabolism still needs be carefully evaluated. In present study, rice seeds were challenged with different doses grown absence/presence NaCl assess these treatments early stages life. Enhanced germination efficiency associated radicle hypocotyl length was observed,...
Proline accumulation in two different bean (Phaseolus vulgaris L.) cultivars, one drought-sensitive (Canario 60) and drought-resistant (Pinto Villa) was investigated. Both tolerated salt concentrations up to 150 mM NaCl, but the sensitive Canario 60 did not survive at 400 NaCl. In response stress, both cvs. accumulated proline all analyzed tissues, lowest contents were detected roots. Pinto Villa higher than only The addition of polyamines or ornithine increased content plant tissues without...
Abstract Seeds of Opuntia spp. have physiological dormancy; they need a period after‐ripening to break dormancy, and the embryos low growth potential. We evaluated combined effects seed age presence fungi on testa germination streptacantha , an abundant species in Chihuahuan Desert (Mexico), assuming that older seeds broken dormancy can reduce mechanical resistance germination. In preliminary experiment, we found no 9‐year‐old (1998) freshly collected (2007) seeds. However, obtained 67% 27%...
Dehydrins (DHNs) are intrinsically disordered proteins that play central roles in plant abiotic stress responses; however, how they work remains unclear. Herein, we report the planta subcellular localization of Arabidopsis thaliana DHNs AtCOR47, AtERD10, and AtRAB18 through GFP translational fusions. To explore dimerization ability acidic AtCOR47 conducted an DHN binding assay using Bimolecular Fluorescence Complementation (BiFC) technique. Our analyses revealed homodimeric interactions for...
DnaJ proteins are essential co-chaperones involved in abiotic and biotic stress responses. Arabidopsis AtDjA3 gene encodes a molecular co-chaperone of 420 amino acids, which belongs to the J-protein family. In this study, we report functional characterization using knockout line designated j3 35S::AtDjA3 overexpression lines. Loss function was associated with small seed production. fact, mutant seeds showed reduction 24% weight compared Col-0 seeds. Expression analysis that modulated...
Abstract In arid and semiarid regions, low precipitation rates lead to soil salinity problems, which may limit plant establishment, growth, survival. Herein, we investigated the NaCl stress effect on chlorophyll fluorescence, photosynthetic-pigments, movement chloroplasts ultrastructure in chlorenchyma cells of Opuntia streptacantha cladodes. Cladodes segments were exposed salt at 0, 100, 200, 300 mM for 8, 16, 24 h. The results showed that reduced content, F v / m , ΦPSII, qP values. Under...
Abstract Turbinicarpus lophophoroides (Werderm) and pseudopectinatus (Backeb) are cacti species under special protection status. Both have seed dormancy. To help preserve these we ran germination experiments to determine the effect of age putrescine on breaking The treatments used were (from four different years) administration exogenous (0.1 μmol/L, 0.1 mmol/L a control). collection years 2001, 2002, 2004 2005 for T. , 2003, . response variable evaluated was final percentage. showed...
The cactus OpsDHN1 dehydrin belongs to a large family of disordered and highly hydrophilic proteins known as Late Embryogenesis Abundant (LEA) proteins, which accumulate during the late stages embryogenesis in response abiotic stresses. Herein, we present vivo subcellular localization by N-terminal GFP translational fusion; our results revealed cytoplasmic nuclear GFP::OpsDHN1 protein Nicotiana benthamiana epidermal cells. In addition, dimer assembly planta using Bimolecular Fluorescence...
