This study attempted to understand some universal relations to fruit Ca uptake across species. Ca contents in fruit tissues were analyzed in different fruits, including three cultivars of litchi, two cultivars each of grape and citrus, and one cultivar each of loquat, apple, pear, Indian jujube and longan. Physiological and molecular characterization of two genetically diverse spring wheat (Triticum aestivum L.) cultivars for salt tolerance. Dr. Samina Tanwir ag (), UAF.

Consumers prefer newer apple cultivars and are willing to pay more for them compared with older cultivars (Yue and Tong, ). ‘Honeycrisp’ apple, a relatively new cultivar with high consumer demand, has been widely planted in the U.S., and a number of physiological disorders have been identified through the activities of the NE that. Cold stress seriously affects banana growth, yield and fruit quality. Long noncoding RNAs (lncRNAs) have been demonstrated as key regulators of biotic and abiotic stress in plants, but the identification and prediction of cold responsive mRNAs and lncRNAs in wild banana remains unexplored. In present study, a cold resistant wild banana line from China was used to profile the cold-responsive.

A characterization and comparison of the chilling-stress response in two cultivars of tomato (lycopersicon esculentum) by Randal William Giroux Download PDF EPUB FB2

Since the interest was in the response during early chilling stress (≤24 h, 10°C), samples were harvested at three time points during this period (0, 4 and 24 h). Differentially expressed genes between control (0 h), 4h, and 24h were assessed with empirical Bayes, using available methods in the Limma package for R, and setting a Benjamini Cited by: 5.

Upon exposure to root chilling conditions, the root hydraulic conductance of both tomato species decreases, but S. habrochaites closes its stomata rapidly in response to chilling stress, thereby. Request PDF | Small Heat Shock Proteins and the postharvest chilling tolerance of tomato fruit | Plants have the largest number of small heat shock proteins (sHsps) (15–42 kDa) among eukaryotes.

The bias of our spot picking, which was based largely upon differences between the two cultivars in response to cold stress, is apparent in comparison with the overall Arabidopsis genome.

The greatest proportion (more than half) of proteins identified in ‘Jonsok’ and ‘Frida’ fall into the biological process categories of stress-related. The exogenously applied L-proline enhances plant growth (Fedina et al., ) and crop productivity (Itai and Paleg, ) under chilling stress conditions.

The exogenous application of L-proline was provide tolerance to chilling stress at 5 °C for 2–6 days (Hayat et al., ) as well as had a dose-dependent stimulatory effect on seeds Cited by: 2. The differences in the molecular responses to chilling stress in JM and SJ were elucidated using the Agilent Rice Gene Expression Microarray 4x44K.

Since the interest was in the response during early chilling stress (≤24 h, 10°C), samples were harvested at three time points during this period (0, 4 and 24 h).Cited by: 5. 1. Introduction. The glutathione S-transferases (GSTs, EC ) are a large and complex enzyme family, involved in key metabolic steps in many eukaryotic organisms [1,2,3], including catalyzing the nucleophilic conjugation of the reduced site-specific (G-site) tri-peptide (glutathione, GSH, and Glu-Cys-Gly) into a wide range of electrophilic and hydrophobic substrates, as well as redox Cited by:   Vol Issue 1, January ISSN Comparative proteomic analysis reveals differential protein and energy metabolisms from two tobacco cultivars in response to cold stress Irrigation at the level of evapotranspiration aids growth recovery and photosynthesis rate in tomato grown under chilling stress.

Guoying Liu, Qingjie Du. After washing, tomato fruit were immersed for 7 min in water at 40 °C (HW) or at 20 °C (control), air-dried for 30 min at room temperature, and then stored for 14 days at 5 °C to induce chilling stress, followed by 14 days at 20 °C to allow ripening and symptoms development (Luengwilai et al., a).

Relative humidity was maintained above Cited by:   In field conditions, plants are often simultaneously exposed to multiple biotic and abiotic stresses resulting in substantial yield loss.

Plants have evolved various physiological and molecular adaptations to protect themselves under stress combinations. Emerging evidences suggest that plant responses to a combination of stresses are unique from individual stress by:   Tomato is one of the most often cultivated vegetable species worldwide.

Due to the anti-oxidative and anti-cancer properties of lycopene, tomato consumption as well as production is still increasing. However, its productivity is impaired by a wide range of abiotic stresses, and the establishment of stress-tolerant crops is a key challenge for agricultural by: Chilling stress is considered the major abiotic stress affecting the growth, development, and yield of rice.

To understand the transcriptomic responses and methylation regulation of rice in response to chilling stress, we analyzed a cold-tolerant variety of rice (Oryza sativa L.

Abstract. An investigation aimed at a better understanding of the molecular adaptation mechanisms of salt stress was carried out in 7-d-old tomato Solanum lycopersicum (L.) Mill cultivars Patio and ‘F’, using a proteomic approach. Total proteins were extracted from radicles and hypocotyls collected from both non-saline control and salt-stressed seedlings, and separated by two Cited by: The use of grafting techniques for horticultural crops increases plant tolerance to various abiotic and biotic stresses.

Tomato production under greenhouse conditions relies on plants grafted onto vigorous rootstocks because they sustain crops for longer periods. Growers under Mediterranean conditions usually grow crops in passive greenhouses during the summer and winter season, to provide Author: Francisco Albornoz, Adriana Nario, Macarena Saavedra, Ximena Videla.

TRIFLORA L.) PLUM FRUITS AS AFFECTED BY COLD STORAGE (F. Sottile, F.M. Two mechanisms of aerenchyma formation have been described; schizogeny, in which development results in the cell separation and lysigeny, in which cells die to create the gas space.

While schizogenous aerenchyma provides a fascinating system for study and has been described in detail at a morphological and ultrastructural level, little is known. Ordinary red tomato and watermelon cultivars appear to have a similar carotenoid biosynthetic pathway leading to the synthesis and accumulation of large amounts of lycopene as major fruit pigment (Tadmor et al., ).Lycopene is the linear carotene responsible of the distinctive color of both fruits at full ripeness and has aroused considerable interest as health-promoting phytochemical Cited by: 5.

Tomato ‘Faworyt’ was cultivated in hydroponic system. Nutrient solution was aerated. After 25 days plants were divided into two groups: control (aerated) and stress (hypoxia - medium without aeration) and cultivated for the next 7 days. Roots and leaves of plants were evaluated separately.

Higher nitrate. Intracellular origins of ROS and their multiple damaging effects. Any circumstance in which cellular redox homeostasis is disrupted can lead to oxidative stress or the generation of ROS ().Production of ROS during environmental stress is one of the main causes for decreases in productivity, injury, and death that accompany these stresses in by:   mRNA expression profiles in tomato in response to Alternaria stress.

In order to detect the alteration in expression of genes during Alternaria-stress RNA-seq analysis was performed for two tomato cDNA libraries, Control 1 and Infected 1, constructed with the same RNA preparation that has been used for small RNA transcriptomics.

Sequencing Cited by:. MYB transcription factors play central roles in plant responses to abiotic stresses. How stress affects development is poorly understood. Here, we show that OsMYB3R-2 functions in both stress and developmental processes in rice (Oryza sativa). Transgenic plants overexpressing OsMYB3R-2 exhibited enhanced cold tolerance.

Cold treatment greatly induced the expression of OsMYB3R-2. Introduction. In functional genomics studies, ‘metabolomics’ refers to analysis of the metabolome, the complete set of small molecules (metabolites) present in cells at particular developmental stages, under particular environmental conditions, and in the context of various genetic modifications (Oliver et al., ).Metabolomics is a powerful tool for the characterization of metabolic Cited by: Kant P, Kant S, Gordon M, Shaked R, Barak S.
