Plants can re-programme their transcriptome, proteome and metabolome to deal with environmental and biotic stress. It has been shown that the rhizosphere microbiome has influence on the plant metabolome and on herbivore behaviour. In the present study, Trichoderma gamsii was isolated from
MicroRNAs (miRNAs) play very important roles in plant growth and development as well as phytohormones. More importantly, microRNAs were recently found to be a new growth regulator involved in plant hormone signaling. Therefore, for investigating the expression change of microRNAs in plants exposed
A highly sensitive and accurate multiplex gas chromatography-tandem mass spectrometry (GC-MS/MS) technique is reported for indole-3-acetic acid, abscisic acid, jasmonic acid, 12-oxo-phytodienoic acid and salicylic acid. The optimized setup allows the routine processing and analysis of up to 60 plant
Phytohormones are crucial endogenous modulators that regulate and integrate plant growth and responses to various environmental pollutants, including the uptake of pollutants into the plant. However, possible links between endogenous phytohormone pathways and pollutant accumulation are unclear. Here
In numerous experimental studies, seedlings of the model dicot Arabidopsis thaliana have been raised on sterile mineral salt agar. However, under natural conditions, no plant has ever grown in an environment without bacteria. Here, we document that germ-free (gnotobiotic) seedlings, raised on
The ability of plant growth promoting rhizobacteria (PGPR) for imparting abiotic stress tolerance to plants has been widely explored in recent years; however, the diversity and potential of these microbes have not been maximally exploited. In this study, we characterized four bacterial strains,
Aiming to counteract B deficiency impacts, plants have developed different strategies in order to reach an optimal growth in soils with limited B availability. These include B transport mechanisms that involves a facilitated transport, via channel proteins, and a high-affinity active transport
For the first time, the organ-specific expression pattern of the AtUSP (At3g58450) gene, which also undergoes hormonal regulation, was shown. The USP protein encoded by this gene is involved in seed germination of Arabidopsis thaliana and, unlike abscisic acid, stimulates this process.
Many plant species and/or genotypes are highly recalcitrant to Agrobacterium-mediated genetic transformation, and yet little is known about this phenomenon. Using several Arabidopsis genotypes/ecotypes, the results of this study indicated that phytohormone pretreatment could overcome this
Protein phosphorylation/dephosphorylation is a central post-translational modification in plant hormone signaling, but little is known about its extent and function. Although pertinent protein kinases and phosphatases have been predicted and identified for a variety of hormone responses, classical
OBJECTIVE
Simultaneous analysis of defense-related phytohormones can provide insights into underlying biochemical interactions. Ultra-high-performance liquid chromatographic (UHPLC) techniques hyphenated to electrospray ionization mass spectrometry (ESI-MS) are powerful analytical platforms,
Global transcriptome studies demonstrated the existence of unique plant responses under combined stress which are otherwise not seen during individual stresses. In order to combat combined stress plants use signaling pathways and 'cross talk' mediated by hormones involved in stress and growth
Universal stress proteins (USPs) are known to be expressed in response to various abiotic stresses in a wide variety of organisms, such as bacteria, archaebacteria, protists, algae, fungi, plants, and animals. However, in plants, biological function of most of the USPs still remains obscure. In the
Seed germination in many plant species is triggered by sunlight, which is rich in the red (R) wavelength and repressed by under-the-canopy light rich in far red (FR). R:FR ratios are sensed by phytochromes to regulate levels of gibberellins (GAs) and abscisic acid (ABA), which induce and inhibit
