Abstract The phenotype of a common bean plant is often closely related to its yield, and the yield of plants with reduced height or poor stem development during growth is low. Mutants serve as an essential gene resource for common bean breeding genetic research. Although model plants and crops are studied to comprehend the molecular mechanisms and genetic basis of plant phenotypes, the molecular mechanism of phenotypic variation in common beans remains underexplored. We here used the mutant ‘nts’ as material for transcriptome sequencing analysis. This mutant was obtained through ⁶⁰Co-γ irradiation from the common bean variety ‘A18’. Differentially expressed genes… More >

Abstract Hot pepper (Capsicum annuum L.) is consumed as one of the oldest domesticated crops all over the world. Although mutation breeding using radiation has been performed in hot peppers, little is known about the comparative analysis of mutagenic effects at the molecular level by ion beam irradiation. To comprehend the response mechanism of hot pepper to the ion beam, we used a mutant with favorable economic characteristics induced by lithium-ion beam irradiation to investigate the biological effects. The results indicated that the lithium-ion beam had a positive effect on important agronomic traits, particularly yield unit, but had a negligible effect… More >

Abstract Various strains of powdery mildew (PM), a notorious plant fungal disease, are prevalent and pose a significant threat to plant health. To control PM, transgenic technology can be used to cultivate more resistant plant varieties. In the present study, we utilized the rapid amplification of cDNA ends (RACE) technique to clone the full-length cDNA sequence of the EuCHIT30.7 gene to explore plant genes with disease resistance functions. Bioinformatics analysis revealed that this gene belongs to the GH18 family and is classified as a class III chitinase. The EuCHIT30.7 gene is expressed throughout the Eucommia ulmoides plant, with the most abundant… More >

Abstract Due to climate change, it is necessary to develop plant varieties that are resilient to climate conditions and resistant to abiotic and biotic stresses. The use of microalgae, which are microorganisms that contain carbohydrates, proteins, lipids, and vitamins, against drought tolerance is a new approach. The aim of the current study was to determine the drought-related mechanisms in the conomon melon genotype and develop drought-tolerant melon cultivars. Morphological, physiological, pomological, and molecular analyses were carried out on the algae-treated genotypes. It has been determined that commercial algae application provides the best results in leaf temperature, leaf relative water contents (LRWC),… More >

Abstract One hundred twenty-five endophytic microorganisms were isolated from the roots, stems, and leaves of four prominent rice cultivars growing in temperate regions. Their potential to combat rice blast disease and promote plant growth was investigated. The dual culture tests highlighted the strong antagonistic activity of five fungal (ranging from 89%–70%) and five bacterial (72%–61%) endophytes. Subsequent examination focused on volatile compounds produced by selected isolates to counter the blast pathogen. Among these, the highest chitinase (13.76 µg mL⁻¹) and siderophore (56.64%), was exhibited by Aspergillus flavus, and the highest HCN production was shown by Stenotrophomonas maltophilia (36.15 µM mL⁻¹).

Abstract The canopy temperature of rice is an important index that directly reflects the growth and physiological state of rice, and affects the yield of rice plants to a great extent. The correlation between the temperatures of different rice organs and canopy in different growth stages and the grain yield is complex. The stability and universality of these correlations must be verified. We conducted a pot experiment using two rice varieties and two temperature treatments (high temperature treatment was carried out at the beginning of heading stage for 10 days). We measured rice organ temperature during seven stages of growth using… More >

Abstract The effect of genotypic diversity on the age structure and bud bank of the Leymus chinensis population has not yet been demonstrated. This experiment was designed to study the age structure of the tiller, rhizome, and bud of L. chinensis at genotypic diversity levels of 1, 2, 4, 8, and 12. A total of 64 communities were established in this experiment, following the principle of randomized block experimental design. The results indicated that genotypic diversity had a significant or obviously significant effect on the cumulative length of rhizomes of 2a and 4a, dry matter accumulation of rhizomes of 1a and… More >

Abstract Drought is one of the critical limitations to agricultural soils and crop plants. Scarcity of water is increasing due to climate change that lead to increasing threats to global food security. Therefore, ecofriendly and cost effective strategies are highly desirable for mitigating drought stress along with sustainable and smart agricultural production. The aim of the study was to mitigate DS using seed priming and exogenous supplementation of β-aminobutyric acid (BABA) in linseed (Linum usitatissimum L.). Different doses (0, 50, 100 and 150 µM) of BABA were used for seed priming agent and foliar spraying under three soil moisture levels viz.,… More >
