Drought represents a major threat to plants in natural ecosystems and agricultural settings. The biostimulant Super Fifty (SF), produced from the brown alga Ascophyllum nodosum, enables ecologically friendly stress mitigation. We investigated physiological whole-genome transcriptome responses of Arabidopsis thaliana drought after treatment with SF. SF strongly decreased drought-induced damage. Accumulation reactive oxygen species (ROS), which typically stifle plant growth during drought, was...
Abiotic stresses cause oxidative damage in plants. Here, we demonstrate that foliar application of an extract from the seaweed Ascophyllum nodosum, SuperFifty (SF), largely prevents paraquat (PQ)-induced stress Arabidopsis thaliana. While PQ-stressed plants develop necrotic lesions, pre-treated with SF (i.e., primed plants) were unaffected by PQ. Transcriptome analysis revealed induction reactive oxygen species (ROS) marker genes, genes involved ROS-induced programmed cell death, and...
Abiotic stresses, which at the molecular level leads to oxidative damage, are major determinants of crop yield loss worldwide. Therefore, considerable efforts directed towards developing strategies for their limitation and mitigation. Here superoxide-inducing agent paraquat (PQ) was used generate stress in model species Arabidopsis thaliana crops tomato pepper. Pre-treatment with biostimulant SuperFifty (SF) effectively universally suppressed PQ-induced leaf lesions, H2O2 build up, cell...
Abstract Oxidative stress can lead to plant growth retardation, yield loss, and death. The atr7 mutant of Arabidopsis thaliana exhibits pronounced tolerance oxidative stress. Using positional cloning, confirmed by knockout RNA interference (RNAi) lines, we identified the mutation revealed that ATR7 is a previously uncharacterized gene with orthologs in other seed plants but no homology genes lower plants, fungi or animals. Expression - GFP fusion shows nuclear-localized protein. RNA-seq...
A monoclonal antibody, JIM 20, derived against an extensin type of hydroxyproline-rich glycoprotein (HRGP) from pea, showed high affinity for HRGP in pearl millet [Pennisetum glaucum (L.) R. Br.]. Electrophoretic separation Tris–SDS extracted proteins suspension cells revealed a range PM-HRGP polypeptides having glycan epitope, which reacted with 20. molecular mass band, probably aggregate or polymer, and few low were recognized by 20 during Western blot analysis. Treatment hydrogen peroxide...
Polygalacturonases (PGs) are hydrolytic enzymes employed by several phytopathogens to weaken the plant cell wall degrading homopolygalacturonan, a major constituent of pectin. Plants fight back employing polygalacturonase-inhibitor proteins (PGIPs). The present study compared inhibition potential pearl millet PGIP (Pennisetum glaucum; PglPGIP1) with known Phaseolus vulgaris (PvPGIP2) against two PGs, PG-II isoform from Aspergillus niger (AnPGII) and PG-III Fusarium moniliforme (FmPGIII). key...
Proline/hydroxyproline-rich glycoprotein (P/HRGP) level in pearl millet genotypes resistant to downy mildew increase after inoculation with the oomycete pathogen Sclerospora graminicola. Using purified P/HRGPs from cell walls, polyclonal antibodies (Pab-P/HRGP) were raised rabbit. Based on this antiserum, an enzyme immunoassay was developed that displays a linearity detection range 0.01 10 μg P/HRGP. Western blot analysis, confirming induction of three marker infected genotype, and...
Introduction The production of high-quality food for the growing world population on one hand and reduction chemical-synthetic pesticides other represents a major challenge agriculture worldwide. effectiveness combination microbial non-microbial biostimulants (BSs) with various nitrogen (N) forms in pathogen defense is discussed as promising, but still poorly understood bio-based alternative crop protection. Methods For this reason, nitrate stabilized ammonium fertilizer both combined...
