Salt stress negatively affects the growth, development, and yield of horticultural crops. Nitric oxide (NO) is considered a signaling molecule that plays key role in plant defense system under salt stress. This study investigated impact exogenous application 0.2 mM sodium nitroprusside (SNP, an NO donor) on tolerance physiological morphological characteristics lettuce (Lactuca sativa L.) (25, 50, 75, 100 mM). caused marked decrease yield, carotenoids photosynthetic pigments stressed plants...
Non-self-recognition of microorganisms partly relies on the perception microbe-associated molecular patterns (MAMPs) and leads to activation an innate immune response. Bacillus subtilis produces three main families cyclic lipopeptides (LPs), namely surfactins, iturins fengycins. Although LPs are involved in induced systemic resistance (ISR) activation, little is known about defence responses by these molecules their involvement local fungi. Here, we showed that purified surfactin,...
Several plant growth-promoting rhizobacteria (PGPR) are known to improve tolerance multiple stresses, including low temperatures. However, mechanisms underlying this protection still poorly understood. The aim of study was evaluate the role endophytic PGPR, Burkholderia phytofirmans strain PsJN (Bp PsJN), on Arabidopsis thaliana cold using photosynthesis parameters as physiological markers. Under standard conditions, our results indicated that Bp inoculation led growth promotion plants...
Plant innate immunity serves as a surveillance system by providing the first line of powerful weapons to fight against pathogen attacks. Beneficial microorganisms and Microbial-Associated Molecular Patterns might act signals trigger this immunity. Burkholderia phytofirmans PsJN, highly efficient plant beneficial endophytic bacterium, promotes growth in wide variety plants including grapevine. Further, bacterium induces resistance abiotic biotic stresses. However, no study has deciphered...
Abnormal temperatures induce physiological and biochemical changes resulting in the loss of yield. The present study investigates impact PsJN strain Paraburkholderia phytofirmans on tomato (Lycopersicon esculentum Mill.) response to heat stress (32°C). results this work showed that bacterial inoculation with P. increased growth parameters such as chlorophyll content gas exchange at both normal high (25 32°C). At temperature (25°C), rate photosynthesis photosystem II activity significant...
Ionic liquids (ILs) are considered as suitable candidates for lignocellulosic biomass pretreatment prior enzymatic saccharification and, obviously, second-generation bioethanol production. However, several reports showed toxic or inhibitory effects of residual ILs on microorganisms, plants, and animal cells which could affect a subsequent fermentation process.In this context, the impact two hydrophilic imidazolium-based already used in was investigated: 1-ethyl-3-methylimidazolium acetate...
Owing to the large genetic diversity of barley and its resilience under harsh environments, this crop is great value for agroecological transition need reduction nitrogen (N) fertilizers inputs. In present work, we investigated a North African genotype collection in terms growth limiting N (LN) or ample (HN) supply physiological traits including amino acid content young seedlings. We identified Moroccan variety, Laanaceur, accumulating five times more lysine leaves than others both...
Natural rhamnolipids are potential biocontrol agents for plant protection against bacterial and fungal diseases. In this work, we synthetized new synthetic mono-rhamnolipids (smRLs) consisting in a rhamnose connected to simple acyl chain differing by the nature of link length lipid tail. We then investigated effects these ether, ester, carbamate or succinate smRL derivatives on Botrytis cinerea development, symptoms spreading tomato leaves immune responses plants. Our results demonstrate...
Abstract In Arabidopsis thaliana, zygotic embryo divisions are highly regular, but it is not clear how patterning established in species or culture systems with irregular cell divisions. We investigated this using the Brassica napus microspore embryogenesis system, where male gametophyte reprogrammed vitro to form haploid embryos absence of exogenous growth regulators. Microspore formed via two pathways: a zygotic-like pathway, characterized by initial suspensor formation followed proper...
The study aimed for evaluate the efficacy of Pseudomonas knackmussii MLR6 on growth promotion, photosynthetic responses, pigment contents and gene expression plant model Arabidopsis thaliana under NaCl stress.
Abstract Plant-associated Burkholderia spp. have been shown to offer a promising alternative method that may address concerns with ecological issue associated pesticide overuse in agriculture. However date, little work has studied the role of species as biocontrol agents for grapevine pathogens. To this end, two strains, BE17 and BE24 isolated from maize rhizosphere France, were investigated determine their potential ability induce systemic resistance against grey mould disease grapevine....
Stilbenes are specialized metabolites that particularly abundant in Vitis species. Although the biosynthetic pathways of stilbenes have been well-characterized, role specific peroxidases stilbene oligomerization remains to be investigated. In this study, we used grapevine cell cultures characterize functional vinifera peroxidase 4 (VvPRX4) production resveratrol oligomers after elicitation with methyl jasmonate (MeJA). We showed MeJA triggers accumulation t-resveratrol, dimers, and predicted...
