Abstract During the evolution, plants acquired the ability to synthesize different phenylpropanoid compounds like chlorogenic acid (CGA), which plays vital roles in resistance mechanisms to abiotic stresses. These environmental factors, including heavy metal, cold, heat, ultraviolet (UV) light, drought, and salinity affect the plant physiological processes, resulting in massive losses of agriculture production. As plants evolve from green algae to bryophytes, ferns, gymnosperms and angiosperms, phenylpropanoids are produced and accumulated in different tissues, giving the plant the capacity to counteract the harmful effects of the adverse environments. Studies have been performed on the metabolic evolution of… More >

Abstract Low-temperature storage is convenient for postharvest preservation of peach fruit, but peach fruit is sensitive to cold damage, which lowers its quality. Nitric oxide (NO) has the potential to improve the bitter resistance of peach fruit. In this work, peach fruit was treated with 15 μmol L⁻¹ NO and 5 μmol L⁻¹ c-PTIO [2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxo-3-oxide], to study changes in mitochondrial fatty acids and expression of the C-repeat binding factor (CBF). The results showed that 15 μmol L⁻¹ exogenous NO significantly maintained fruit quality, reduced peroxidation of mitochondrial fatty acids, increased the activities of the antioxidants superoxide dismutase (SOD),… More >

Abstract Slow growth rate restricts the development and growth of seedlings due to nutrients deficiency or nutrient imbalance. Exponential fertilization can enhance the internal nutrient reserves in seedlings at the nursery-stage and strengthen their resistance to adverse conditions. In this study, nitrogen requirements for producing Hydrangea macrophylla ‘Hanatemari’ that robust seedlings, nutrient dynamics, biomass and growth, was examined utilizing exponential fertilization. The potted seedlings were fertilized with urea under exponential regime at rates of 0.5, 1.5 and 2.0 g nitrogen/plant (EF1, EF2, and EF3), respectively. In addition, an unfertilized group treated with equal volume of deionized water… More >

Abstract Tripterygium wilfordii has been renowned mostly because of the anticancer effects of its root extracts, which is partly ascribed to the presence of celastrol, a pentacyclic triterpenoid, as one of the main active components. Celastrol also has recently been reported as an effective prodrug in the treatment of obesity. Despite the promising activities, the pathway leading to celastrol biosynthesis, especially cytochrome P450 (CYP) enzyme(s) that occur in its downstream steps, are largely unknown. This study conducted a comparative analysis of the T. wilfordii transcriptome derived from its root and leaf tissues. Differential gene expression analysis identified a More >

Abstract Soybean oleic acid content is one of the important indexes to evaluate the quality of soybean oil. In the synthesis pathway of soybean fatty acids, the FAD2 gene family is the key gene that regulates the production of linoleic acid from soybean oleic acid. In this study, CRISPR/Cas9 gene editing technology was used to regulate FAD2 gene expression. Firstly, the CRISPR/Cas9 single knockout vectors GmFAD2-1B and GmFAD2-2C and double knockout vectors GmFAD2-2A-3 were constructed. Then, the three vectors were transferred into the recipient soybean variety Jinong 38 by Agrobacterium-mediated cotyledon node transformation, and the mutant plants were obtained. More >

Abstract Sugarcane is one of the major important sugar yielding crops in Bangladesh. As an exhaustive crop, sugarcane removes a huge amount of plant nutrients from the soil. However, the combined use of organic and inorganic fertilizers can be a good approach to deal with nutrient depletion and promote sustainable crop production as well as improve soil health. Therefore, an attempt was made to identify the most fruitful and profitable integrated nutrient management on the aspects of growth, yield and quality of sugarcane in two consecutive growing seasons. Seven treatments: T₁=Control, T₂=165:55:120:30:10:2.5:4 kg N:P:K:S:Mg:Zn:B ha⁻¹, T₃=Poultry Litter (PL) at… More >

Abstract The “super rice” breeding program in China has been successful in developing high-yielding hybrids, including few with high harvest index values. However, there is limited information on the relationship between lodging resistance and harvest index, and the mechanisms underlying the relationship in super-rice hybrids. In this study, a two-year field experiment was conducted to compare lodging resistance and its related traits between two super-rice hybrids differing in harvest index, i.e., Guiliangyou 2 (G2) with a high harvest index and Y-liangyou 1 (Y1) with a typical harvest index of modern high-yielding rice varieties. Results showed that More >

Abstract BEL1-like homeodomain (BLH) family proteins are homeodomain transcription factors, which are found ubiquitously in plants and play important roles in regulating meristem and flower development. Although BLH proteins have been reported in some plant species, there is very little information available for plants in the Malus genus (e.g., apple tree:Malus domestica). In the present study, we identified 19 apple MdBLH genes. Phylogenetic analysis revealed that the MdBLH genes could be divided into five groups. Analysis of gene structure showed that MdBLH gene has four exons, and the third exon was 61 bp in length. Chromosomal location analysis suggested that… More >

Abstract Ananas comosus var. bracteatus is an important ornamental plant because of its green/white chimeric leaves. The accumulation of anthocyanin makes the leaf turn to red especially in the marginal part. However, the red fades away in summer and winter. Light intensity is one of the most important factors affecting leaf color along the seasons. In order to understand the effects of light intensity on the growth and coloration of the chimeric leaves, Ananas comosus var. bracteatus was grown under full sunlight, 50% shade and 75% shade for 75 days to evaluate the concentration of pigments, the color parameters… More >

Abstract Plants in natural ecosystems are exposed to a combination of UV radiation, ionizing radiation (IR) and other abiotic factors. These factors change with the altitude. We investigated DNA alterations of some wild plants of different plant families in natural ecosystems at three altitudes in Rila Mountain, Bulgaria (1500, 1782, and 2925 m above sea level (a.s.l.) exposed to UV radiation, IR and other abiotic stresses, to assess the tolerance of plant species to the changing environmental conditions in three successive growth seasons. For this purpose, physicochemical, cytogenetic, and molecular methods were applied. DNA damage was assessed… More >
