Melatonin (MT; N-acetyI-5-methoxytryptamine) is an amine hormone involved in abiotic stress resistance. Previous studies have confirmed that melatonin can promote seed germination, mediate physiological regulation mechanisms, and stimulate crop growth under stress. However, the osmotic mechanism by which exogenous mediates salt tolerance cotton still largely unknown. To investigate effect of on concentration germinating seeds, we analyzed content over time during germination different...
Although previous studies have found that melatonin can promote seed germination, the phytohormone regulation mechanism by which exogenous mediates salt tolerance during cotton germination is still largely unknown. The effects of on traits and physiological parameters GXM9 seeds (Gossypium hirsutum L.) under three stress treatments (CK, pretreated with water alone; S, in 150 mM NaCl stress; SM, 20 μM solution) laboratory was investigated. results showed (150 mM) inhibited endogenous...
Seed germination is considered the beginning of spermatophyte lifecycle, and it a crucial stage in determining subsequent plant growth development. Although many previous studies have found that melatonin can promote seed germination, role cotton remains unexamined. The main objective this study characterization potential promotional effects (at doses 0, 10, 20, 50, 100 200 μM) on germination. This experiment demonstrated low concentrations while high failed to even inhibited Together, these...
The root system plays an important role in the growth and development of cotton, is closely related to shoot growth, both which are affected by N availability soil. However, it unknown how affects root-shoot relationship under various rates Yellow River Basin, China. Thus, aim this study was assess impacts application rate on relationship, provide insight into regulation efficiency from perspective system. A field experiment conducted 2014 2015 used determine effects (0, 120, 240, 480 kg...
Abstract Background As damage to the ecological environment continues increase amid unreasonable amounts of irrigation, soil salinization has become a major challenge agricultural development. Melatonin (MT) is pleiotropic signal molecule and indole hormone, which alleviates abiotic stress plants. MT been confirmed eliminate reactive oxygen species (ROS) by improving antioxidant system reducing oxidative under adversity. However, mechanism exogenous mediates salt tolerance regulating...
The germination of cotton ( Gossypium hirsutum L.) seeds is affected by drought stress; however, little known about the physiological mechanism affecting and effect melatonin (MT) on seed under stress. Therefore, we studied effects exogenous MT antioxidant capacity epidermal microstructure results demonstrated a retarded water absorption testa stress, significantly inhibiting growth in seeds. Drought stress led to accumulation reactive oxygen species (ROS), malondialdehyde (MDA),...
Root systems are the key organs through which plants absorb water and nutrients perceive soil environment thus easily damaged by salt stress. Melatonin can alleviate stress-induced damage to roots. The present study investigated effects of exogenous melatonin on root physiology, transcriptome metabolome cotton seedlings under Salt stress was observed cell structure disorder physiological system seedling After subjecting melatonin-soaked seeds stress, activities SOD, CAT POD in roots...
Melatonin (N-acetyl-5-methoxytryptamine, MT) can mitigate abotic stress, including drought stress on a number of crops. However, it is unclear whether and how seed priming with melatonin alleviates the effects germination seedling growth triticale ( Triticale hexaploide L.). In this study, we investigated MT germination, protective enzyme activity, superoxide anion, hydrogen peroxide in under PEG-6000 induced stress. Seed 20 μM alleviated adverse growth. seeds primed exhibited improved...
Abstract Background Root system architecture (RSA) exhibits significant genetic variability and is closely associated with drought tolerance. However, the evaluation of drought-tolerant cotton cultivars based on RSA in field conditions still underexplored. Results So, this study conducted a comprehensive analysis tolerance physiological morphological traits (i.e., aboveground RSA, yield) within rain-out shelter, two water treatments: well-watered (75 ± 5% soil relative content) stress (50...
Abstract Background Cotton ( Gossypium hirsutum L.) is one of the most important cash crops worldwide. Fine roots are central part root system that contributes to plant water and nutrient uptake. However, mechanisms underlying response cotton fine soil drought remains unclear. To elucidate proteomic changes in plants under stress, 70–75% 40–45% relative content treatments were imposed on control (CK) stress (DS) groups, respectively. Then, tandem mass tags (TMT) technology was used determine...
Abstract Lateral roots and root hairs are essential portions of cotton roots. However, the morphology lifespan ( Gossypium hirsutum L.) lateral in response to nitrogen stress have remained unknown. Two cultivars were assessed when no normal (138 mg N·kg −1 soil) added. The daily acquisitions phenotype information including angle, density, diameter, lifespan, hair length, obtained situ by a self‐designed platform RhizoPots equipped with high‐resolution scanners. Nitrogen starvation...
Quantitative analysis of root development is becoming a preferred option in assessing the function hidden underground roots, especially studying resistance to abiotic stresses. It can be enhanced by acquiring non-destructive phenotypic information on such as rhizotrons. However, it challenging develop high-throughput phenotyping equipment for and analyzing situ images development. In this study, RhizoPot platform, platform integrating plant culture, automatic image acquisition, segmentation,...
Melatonin application has obvious improving effects on alleviating the drought-induced inhibition of plant growth. However, root phenotypic dynamics in wheat treated with melatonin remain unknown. This study was conducted using RhizoPot, a novel and improvised situ observation device, three treatments, including normal water condition (CK), drought (Ds, relative content 45–50%), 100 µM treatment under (MT). Results showed that MT effectively improves morphological indicators, (specific root)...
Phosphorus (P) deficiency is a common challenge in crop production because of its poor mobility through the soil. The root system plays significant role P absorption from soil and initial indicator low levels. However, phenotypic dynamics longevity cotton roots under stress remain unknown. In this study, RhizoPot, an improvised situ observation device, was used to monitor phenotypes seedlings P-deficient (PD) P-replete (PR) conditions. Low reduced accumulation roots, leading dry weight...
The chlorophyll fluorescence parameter F v /F m is significant in abiotic plant stress. Current acquisition methods must deal with the dark adaptation of plants, which cannot achieve rapid, real-time, and high-throughput measurements. However, increased inputs on different genotypes based hyperspectral model recognition verified its capabilities handling large variable samples. a drought tolerance index reflecting best tolerant cotton genotype. Therefore, prediction varieties, evaluation,...
Abstract In cell–cell communication, noncell-autonomous transcription factors play vital roles in controlling plant stem cell fate. We previously reported that AUXIN RESPONSE FACTOR3 (ARF3), a member of the ARF family with critical floral meristem maintenance and determinacy, has distinct accumulation pattern differs from expression domain its encoding gene shoot apical (SAM). However, biological meaning this difference is obscure. Here, we demonstrate ARF3 Arabidopsis (Arabidopsis thaliana)...
