Arbuscular mycorrhizal (AM) symbiosis alleviates drought stress in plants. However, the intimate mechanisms involved, as well its effect on production of signalling molecules associated with host plant-AM fungus interaction remains largely unknown. In present work, effects lettuce and tomato plant performance hormone levels were investigated non-AM AM Three different water regimes applied, their analysed over time. plants showed an improved growth rate efficiency photosystem II than under...
Plant growth-promoting rhizobacteria (PGPR) are naturally occurring soil bacteria which benefit plants by improving plant productivity and immunity. The mechanisms involved in these processes include the regulation of hormone levels such as ethylene abscisic acid (ABA). aim present study was to determine whether activity Bacillus megaterium PGPR is affected endogenous ABA content host plant. ABA-deficient tomato mutants flacca sitiens their near-isogenic wild-type parental lines were used....
The role of jasmonic acid in the induction stomatal closure is well known. However, its regulating root hydraulic conductivity (L) has not yet been explored. objectives present research were to evaluate how JA regulates L and calcium abscisic (ABA) could be involved such regulation. We found that exogenous methyl jasmonate (MeJA) increased Phaseolus vulgaris, Solanum lycopersicum Arabidopsis thaliana roots. Tomato plants defective biosynthesis had lower values than wild-type plants, was...
The jasmonate (JA)-pathway regulators MYC2, MYC3, and MYC4 are central nodes in plant signaling networks integrating environmental developmental signals to fine-tune JA defenses growth. Continuous activation of MYC activity is potentially lethal. Hence, MYCs need be tightly regulated order optimize fitness. Among the increasing number mechanisms regulating activity, protein stability arising as a major player. However, how levels proteins modulated still poorly understood. Here, we report...
Summary Phosphate (Pi) is an essential nutrient for all organisms. Roots are underground organs, but the majority of root biology studies have been done on systems growing in presence light. Root illumination alters Pi starvation response ( PSR ) at different intensities. Thus, we analyzed morphological, transcriptional and physiological responses to dark‐grown roots. We identified new genes pathways regulated by that were not described previously. also show Pi‐starved plants increase...
Different plant species employ different jasmonates to activate a conserved signalling pathway in land plants, where (+)-7-iso-JA-Ile (JA-Ile) is the ligand for COI1/JAZ receptor angiosperms and dn-cis-OPDA, dn-iso-OPDA Δ4 -dn-iso-OPDA act as ligands Marchantia polymorpha. In addition, some play COI1-independent role. To understand distribution of bioactive green lineage how their biosynthetic pathways evolved, we performed phylogenetic analyses systematic profiling representative from...
It is known that the presence of arbuscular mycorrhizal fungi within plant roots enhances tolerance host to different environmental stresses, although positive effect in plants under waterlogged conditions has not been well studied. Tolerance flooding can be achieved through molecular, physiological and anatomical adaptations, which will affect their water uptake capacity therefore root hydraulic properties. Here, we investigated properties non-flooded flooded non-mycorrhizal tomato...
The physiological and metabolic mechanisms behind the humic acid-mediated plant growth enhancement are discussed in detail. Experiments using cucumber (Cucumis sativus) plants show that shoot caused by a structurally well-characterized acid with sedimentary origin is functionally associated significant increases abscisic (ABA) root concentration hydraulic conductivity. Complementary experiments involving blocking agent of cell wall pores water transport (polyethylenglycol) conductivity...
