Abstract Cadmium (Cd) and Mercury (Hg) is among the heavy metals most hazardous for plant and human health. Known to induce oxidative stress in plants and disbalance equilibrium in the antioxidant defence system, these metals alter plant growth and cause damage at the cellular and molecular levels. Soybean is an important oilseed crop that is raised in soils often contaminated by Cd and Hg. The comparative studies on the deleterious effect of Cd and Hg and the defence system of antioxidants were not studied earlier in soybean plant. In this study, soybean plants were exposed to Cd (100 µM CdCl₂) and… More >

Abstract Banana is a tropical crop cultivated in warm places. Chilling stress in Egypt is making banana crops less productive. Abscisic acid (ABA), a key plant hormone, regulates metabolic and physiological processes and protects plants from a variety of stresses. In vitro growing banana shoots were pre-treated with ABA at four concentrations (0, 25, 50, and 100 mM) and chilled at 5°C for 24 h, followed by a six-day recovery period at 25°C. By comparing ABA treatments to both positive and negative controls, physiological and biochemical changes were investigated. Chilling stress (5°C) caused a considerable increase in lipid peroxidation and ion… More >

Abstract Abiotic stresses at different growth stages in the life of plants negatively affect yield productivity. Therefore, plants, including Amaranthus hypochondriacus, develop adaptive strategies to face the stresses and expand functional diversification. In plants, the mitochondrial transcription termination factors (mTERF) are essential functions in regulation, and organelles (mitochondria and chloroplasts) control gene expression (OGE) under several stress conditions. Based on the in-silico-wide genome and transcriptome analysis, twenty-four mTERF genes were detected in the main targeted mitochondria organelles clustered into three different main groups. The chromosomal location and gene duplication analysis indicated one segmental and one tandem duplication in the genome. The… More >

Abstract Castor (Ricinus communis L.) is one of ten oil crops in the world and has complex inflorescence styles. Generally, castor has three inflorescence types: single female inflorescence (SiFF), standard female inflorescence (StFF) and bisexual inflorescence (BF). StFF is realized as a restorer line and as a maintainer line, which was applied to castor hybrid breeding. However, the developmental mechanism of the three inflorescences is not clear. Therefore, we used proteomic techniques to analyze different inflorescence styles. A total of 72 diferentially abundant protein species (DAPs) were detected. These DAPs are primarily involved in carbon and energy metabolism and carbon fixation… More >

Abstract In arid and semi-arid sand dune ecosystems, belowground bud bank plays an important role in population regeneration and vegetation restoration. However, the responses of belowground bud bank size and composition to sand burial and its induced changes in soil environmental factors have been rarely studied. In arid sand dunes of Northwestern China, we investigated belowground bud bank size and composition of the typical rhizomatous psammophyte Psammochloa villosa as well as three key soil environmental factors (soil moisture, total carbon and total nitrogen) under different depths of sand burial. Total buds and rhizome buds increased significantly with increasing burial depth, whereas… More >

Abstract Drought is one of the major abiotic threat to rice production in the context of climate change. Super Basmati is an elite, fine grain basmati rice variety grown in Punjab, Pakistan. Due to drought sensitive in nature, its yield has been facing an alarming situation in production because of gradual decrease in irrigated water for a couple of years. Three reported novel QTLs for drought tolerance were selected for incorporation into Super Basmati by employing marker assisted selection strategy. IR55419-04 with novel QTLs was used as a donor parent. Foreground selection was performed by applying PCR based QTL linked SSR… More >

Abstract Appropriate knowledge of the parental cultivars is a pre-requisite for a successful breeding program. This study characterized fruit yield, quality attributes, and molecular variations of ten tomato cultivars during three consecutive generations under greenhouse conditions. Peto 86, Castle Rock, and Red Star cultivars showed the highest fruit yield (kg/plant), total phenolic compounds (TPC), and sap acidity. Principal component analysis categorized the evaluated fruit yield into three groups based on their quality attributes. A robust positive correlation appeared among traits inside each group. A positive correlation was likewise noticed between the first and the second groups. However, a negative correlation was… More >

Abstract This present study includes twelve species that represent the Ficus genus, namely; aspera, carica, tinctoria subsp. gibbosa, hirta, hispida, neriifolia, palmata, pumila, racemosa, septica, sur, and sycomorus, belonging to the Moraceae family. The species samples were collected from various locations in Egypt. The study focused on the anatomical and molecular characteristics of mature foliage leaves. Since the identification and classification of taxa are highly dependent on the anatomical features of leaves, the anatomical characteristics were recorded in the form of a comparison between the examined plants in the data matrix. This study aims to contribute to the identification of the… More >

Abstract Drought is a severe environmental constraint, causing a significant reduction in crop productivity across the world. Salicylic acid (SA) is an important plant growth regulator that helps plants cope with the adverse effects induced by various abiotic stresses. The current study investigated the potential effects of SA on drought tolerance efficacy in two barley (Hordeum vulgare) genotypes, namely BARI barley 5 and BARI barley 7. Ten-day-old barley seedlings were exposed to drought stress by maintaining 7.5% soil moisture content in the absence or presence of 0.5, 1.0 and 1.5 mM SA. Drought exposure led to severe damage to both genotypes,… More >

Abstract Chrysanthemum morifolium Ramat is one of the four major cut flowers in the world. Pht1 family is focus on the uptake and transport of phosphate in plants. In our previous studies, CmPht1;2 overexpression line (Oe1) had higher phosphate contents both in roots and shoots, and its root development was significantly enhanced than wild type (WT) at low phosphorus conditions in chrysanthemum. Metabolomics analysis showed that several metabolites had a change in pyruvate metabolism and tricarboxylic acid (TCA) cycle pathway. To explore the gene difference expression and the change of metabolic pathway between CmPht1;2-Oe1 and WT, we conducted the transcriptome analysis.… More >
