The use of bioeffectors, formally known as plant biostimulants, has become common practice in agriculture and provides a number benefits stimulating growth protecting against stress. A biostimulant is loosely defined an organic material and/or microorganism that applied to enhance nutrient uptake, stimulate growth, stress tolerance or crop quality. This review intended provide broad overview effects biostimulants their ability improve abiotic stresses. Inoculation application extracts from...
Sucrose nonfermenting 1 (SNF1)-related protein kinase 2s (SnRK2s) are central components of abscisic acid (ABA) signaling pathways. The snrk2.2/2.3/2.6 triple-mutant plants nearly completely insensitive to ABA, suggesting that most the molecular actions ABA triggered by SnRK2s-mediated phosphorylation substrate proteins. Only a few proteins SnRK2s known. To identify additional and provide insight into we used quantitative phosphoproteomics compare global changes in phosphopeptides WT triple...
Summary Loss‐of‐function siz1 mutations caused early flowering under short days. plants have elevated salicylic acid (SA) levels, which are restored to wild‐type levels by expressing nahG , bacterial salicylate hydroxylase. The of was suppressed indicating that SIZ1 represses the transition mainly through suppressing SA‐dependent floral promotion signaling Previous results shown exogenous SA treatment does not suppress late autonomous pathway mutants. However, mutation accelerated time an...
Tomato is a major crop in the Mediterranean basin, where cultivation open field often vulnerable to drought. In order adapt and survive naturally occurring cycles of drought stress recovery, plants employ coordinated array physiological, biochemical, molecular responses. Transcriptomic studies on tomato responses subsequent recovery are few number. As search for novel traits improve genetic tolerance increases, better understanding these required. To address this need we designed study which...
The emerging roles of rhizobacteria in improving plant nutrition and stress protection have great potential for sustainable use saline soils. We evaluated the function salt-tolerant strain Azotobacter chroococcum 76A as protectant an important horticultural crop, tomato. Specifically we hypothesized that treatment tomato plants with A. could improve performance under salinity sub-optimal nutrient regimen.Inoculation Micro Tom increased numerous growth parameters also conferred protective...
Improving crop performance under water-limiting conditions is essential for achieving environmentally sustainable food production. This requires significant progress in both the identification and characterization of key genetic physiological processes involved water uptake loss. Plants regulate loss through developmental environmental responses. These responses include: root morphology architecture, cuticle development, stomatal guard cell movements response to environment. Genes...
Biostimulants hold great potential for developing integrated sustainable agriculture systems. The rhizobacteria Azotobacter chroococcum strain 76A and the fungus Trichoderma harzianum T22, with demonstrated biostimulant activity in previous systems, were evaluated Triticum durum cv Creso their ability to enhance growth tolerance drought stress. Growth conditions of low high soil nitrogen, two levels water T. increased plant (+16%) under control moderate stress (+52%) optimal fertilization,...
Omeprazole is a selective proton pump inhibitor in humans that inhibits the H+/K+-ATPase of gastric parietal cells. has been recently shown to act as plant growth regulator and enhancer salt stress tolerance. Here, we report omeprazole treatment hydroponically grown maize improves nitrogen uptake assimilation. The presence micromolar concentrations nutrient solution alleviates chlorosis inhibition induced by low availability. Nitrate assimilation enhanced treated plants through changes...
Biostimulants have rapidly and widely been adopted as growth enhancers stress protectants in agriculture, however, due to the complex nature of these products, their mechanism action is not clearly understood. By using two algal based commercial biostimulants combination with Solanum lycopersicum cv. MicroTom model system, we assessed how modulation nitrogen metabolites potassium levels could contribute mediate physiological mechanisms that are known occur response salt/and or osmotic...
Our knowledge base involving the biochemical participants of epigenetic control has expanded greatly over last decade. The role marks to DNA and histones controlled by non-coding RNAs is one most intensely studied areas biology today. This review covers many mechanisms that other molecules use gene expression eventually affect responses environment. In first part review, we discuss array covalent modifications genome constitute epigenome, which consists histone variants, modifications,...
Pre-treatment of tomato plants with micromolar concentrations omeprazole (OP), a benzimidazole proton pump inhibitor in mammalian systems, improves plant growth terms fresh weight shoot and roots by 49% 55% dry 54% 105% under salt stress conditions (200 mM NaCl), respectively. Assessment gas exchange, ion distribution gene expression profile different organs strongly indicates that OP interferes key components the adaptation machinery, including hormonal control root development (improving...
Abscisic acid (ABA) plays an important role in various aspects of plant growth and development, including adaptation to stresses, fruit development ripening. In seeds, ABA participates through its core signaling components dormancy instauration, longevity determination, inhibition germination unfavorable environmental conditions such as high soil salinity. Here, we show that seed pepper was delayed but only marginally reduced by or NaCl with respect control treatments. Through a similarity...
Tomato is a horticultural crop of high economic and nutritional value. Suboptimal environmental conditions, such as limited water nutrient availability, cause severe yield reductions. Thus, selection genotypes requiring lower inputs goal for the tomato breeding sector. We screened 10 varieties exposed to deficit, low nitrate or combination both. Biometric, physiological molecular analyses revealed different stress responses among genotypes, identifying T270 severely affected, T250 tolerant...
Omeprazole (OP) has been shown to act as a plant growth regulator and enhances tolerance salt stress. In this study, two Ocimum basilicum genotypes were tested for their responses OP under The genotypes, Napoletano (NAP) sensitive genotype, Genovese (GEN) tolerant had contrasting treatment. NAP demonstrated increases in terms of (+36%) (+19%) upon treatment while GEN increase (+35%) enhanced sensitivity stress (−13%). also an effect on the post‐harvest behaviour these by increasing shelf...
