During the development of multicellular organisms, organogenesis and pattern formation depend on formative divisions to specify maintain pools stem cells. In higher plants, these activities are essential shape final root architecture because functioning apical meristems de novo lateral roots entirely rely it. We used transcript profiling sorted pericycle cells undergoing initiation identify receptor-like kinase ACR4 Arabidopsis as a key factor both in promoting cell constraining number once...
Like animals, the mature plant body develops via successive sets of instructions that determine cell fate, patterning, and organogenesis. In coordination various developmental programs, several hormones play decisive roles, among which auxin is best-documented hormonal signal. Despite broad range processes influenced by auxin, how such a single signaling molecule can be translated into multitude distinct responses remains unclear. Arabidopsis thaliana , lateral root development classic...
Abstract Multicellular organisms depend on cell production, fate specification, and correct patterning to shape their adult body. In plants, auxin plays a prominent role in the timely coordination of these different cellular processes. A well-studied example is lateral root initiation, which triggers founder specification cycle activation xylem pole–positioned pericycle cells. Here, we report that E2Fa transcription factor Arabidopsis thaliana an essential component regulates asymmetric...
Abstract Multiple plant developmental processes, such as lateral root development, depend on auxin distribution patterns that are in part generated by the PIN-formed family of auxin-efflux transporters. Here we propose AUXIN RESPONSE FACTOR7 (ARF7) and ARF7-regulated FOUR LIPS/MYB124 (FLP) transcription factors jointly form a coherent feed-forward motif mediates auxin-responsive PIN3 planta to steer early steps formation. This regulatory mechanism might endow circuitry with temporal ‘memory’...
In eukaryotes, transcriptional regulation is determined by dynamic and reversible chromatin modifications, such as acetylation, methylation, phosphorylation, ubiquitination, glycosylation, that are essential for the processes of DNA replication, DNA-repair, recombination gene transcription. The rapid changes in histone acetylation induce genome-wide specific alterations expression play a key role modification. Because their sessile lifestyle, plants cannot escape environmental stress, hence...
Small peptides of the Arabidopsis GLV/RGF/CLEL family are involved in different developmental programmes, including meristem maintenance and gravitropic responses. In addition, our previous report suggested that they also participate formation lateral roots. Specifically, GLV6 is transcribed during first stages primordium development overexpression results a strong reduction emerged To investigate cause this phenotype we analysed gain-of-function (gof) mutants found induces supernumerary...
The potential of Marrubium vulgare to alleviate scopolamine (Sco)-induced deficits in spatial working memory has drawn considerable scientific interest. This effect is partly attributed its potent antioxidant and acetylcholinesterase inhibitory (AChEI) activities. study examined the effects M. extract, standardized marrubiin content, on recognition healthy Sco-treated rats. Male Wistar rats (200–250 g) were divided into four groups. extract was orally administered for 21 days Sco (2 mg/kg)...
Plants experience a number of limiting factors, as drought and heat, which are often coinciding stress factors in natural environment. This study evaluated the changes mesophyll cell ultrastructure leaves two varieties winter wheat (Triticum aestivum L.), differing their tolerance, under individual or combined heat treatment. Although affected leaf ultrastructure, damaging effect was more pronounced manifested certain differences between genotypes. Chloroplasts mitochondria were...
Selection and breeding of genotypes with improved drought/heat tolerance become key issues in the course global change predicted increased frequency droughts or heat waves. Several morphological physiological plant traits must be considered. Rooting depth, root branching, nutrient acquisition, mycorrhization, nodulation legumes release nutrients, assimilates phytohormones to shoot are relevant systems. Xylem embolism its repair after a drought, development axillary buds solute channeling via...
Abstract Recurrent drought periods of varying duration often cause extensive crop damage and affect wheat production in Southern Europe. This study compares biochemical ultrastructural responses four ( Triticum aestivum L.) cultivars to long‐term field drought, their contribution final grain yield. Gel electrophoresis immunoblotting analyses combined with transmission electron microscopy yield evaluation were employed assess susceptibility the cultivars. Two them behaved as drought‐tolerant,...
The growth-promoting and heat-mitigating effects of a commercially available protein-hydrolysate-based biostimulant, Kaishi, during the early vegetative stage was investigated by applying it as foliar spray on soil-grown maize plants or in nutrient solution hydroponically grown plants. At 10−3 dilution, biostimulant inhibited germination delayed growth progress, while at 10−6–10−12 dilutions, promoted shoot root growth. Heat stress caused biomass reduction, decreased leaf pigment content...
Sideritis scardica Griseb. and Clinopodium vulgare L., belonging to the Lamiaceae family, are rich in terpenoids phenolics exhibit various pharmacological effects, including antioxidant, anti-inflammatory anti-cancer activities. While memory-enhancing impacts of S. well documented, cognitive benefits C. remain unexplored. This study assessed potential effect on learning memory healthy scopolamine (Sco)-induced memory-impaired male Wistar rats, comparing it with effects scardica. Over a...
ABSTRACT Pea (Pisum sativum cv. Citrine) plants were grown in nutrient solution containing various manganese (Mn) concentrations the presence or absence of succinate to evaluate potential role plant tolerance Mn excess. Supplying pea with excess led a reduction relative growth rate (RGR), chlorophyll and b content, photosynthetic O2 evolution activity, photosystem II (PSII) as measured light-adapted state (φPSII) comparison control. The primary photochemical efficiency PSII, estimated by...
Abstract The incorporation of a fusion green fluorescent protein and tubulin-α 6 from Arabidopsis thaliana in root hairs Lotus japonicus has allowed us to visualize quantify the dynamic parameters cortical microtubules living hairs. Analysis individual microtubule turnover real time showed that only plus polymer ends contributed overall dynamicity, exhibiting instability as main type behavior Comparison four standard vivo instability—the growth rate, disassembly frequency transitions...
In the present study, protective effect of nitric oxide (NO) against Cd-induced structural disturbances in pea (Pisum sativum) leaves was investigated. Cadmium treatment resulted a decreased leaf size and thickness lamina, reduced intercellular spaces mesophyll, small pavement cells, high density stomata. These abnormalities were partially or fully reversed by simultaneous application Cd NO donor, sodium nitroprusside (SNP). The concentration 1000 µM SNP very effective counteracting adverse...
