Foraging resource partitioning between Indian native Apis florea and Apis cerana: unveiling entomological signatures in honey through honey DNA metabarcoding.

Honey DNA metabarcoding provides precise and comprehensive data on the origins of honey and the plants that honey bees select for feeding. Honey produced by both Apis cerana and Apis florea, along with the determination of honey bee floral preferences, has the potential to assist researchers in strategically selecting appropriate plant species that can effectively enhance the growth and prosperity of honey bee colonies. Honey samples collected from 40 places in North Gujarat, India, was produced by two species of honey bees, A.

Elaborating the multifarious role of PGPB for sustainable food security under changing climate conditions.

Changing climate creates a challenge to agricultural sustainability and food security by changing patterns of parameters like increased UV radiation, rising temperature, altered precipitation patterns, and higher occurrence of extreme weather incidents. Plants are vulnerable to different abiotic stresses such as waterlogging, salinity, heat, cold, and drought in their natural environments. The prevailing agricultural management practices play a major role in the alteration of the Earth's climate by causing biodiversity loss, soil degradation through chemical and physical degradation, and pollution of water bodies.

Characterization of causing foot rot: a severe threat of betel vine cultivation in Bangladesh.

Unlabelled: The development of the foot rot disease caused by the fungus is one of the primary variables endangering betel vine production in Bangladesh. Consequently, with the ultimate objective of finding efficient preventive and control strategies for this infamous phytopathogen, the current study was undertaken for comprehensive population structure analysis, exploration of physiological features and incidence patterns of pathogenic isolates. We discovered 22 isolates from nine northern districts of Bangladesh Mohanpur (51.

ER-08, a multifunctional plant growth-promoting rhizobacterium, promotes the growth of fenugreek ( L.) plants under salt and drought stress.

Introduction: Sustainable agriculture and meeting the world's food needs face considerable obstacles from abiotic stresses such as soil salinity and drought. This critical issue was addressed by our current study, which sought to uncover multi-trait bioinoculants from hostile ecosystems that could help mitigate salinity and drought stresses at the same time.

Methods: The ER-08 (BST) strain was isolated from the halotolerant plant Fagonia which was collected from the Little Rann of Kachchh, India.

A Simple Heat Treatment Increases SpCas9-Mediated Mutation Efficiency in Arabidopsis.

The CRISPR/Cas9 system is now commonly employed for genome editing in various plants such as Arabidopsis, rice and tobacco. In general, in genome editing of the Arabidopsis genome, the SpCas9 and guide RNA genes are introduced into the genome by the floral dip method. Mutations induced in the target sequence by SpCas9 are confirmed after selecting transformants by screening the T1 seed population.

Transcriptome Analysis Shows Activation of Stress and Defense Responses by Silencing of Chlorophyll Biosynthetic Enzyme CHLI in Transgenic Tobacco.

In the present study, we have shown the transcriptional changes in a chlorosis model transgenic tobacco plant, i-amiCHLI, in which an artificial micro RNA is expressed in a chemically inducible manner to silence the expression of genes encoding a subunit of a chlorophyll biosynthetic enzyme. Comparison to the inducer-treated and untreated control non-transformants and untreated i-amiCHLI revealed that 3568 and 3582 genes were up- and down-regulated, respectively, in the inducer-treated i-amiCHLI plants. Gene Ontology enrichment analysis of these differentially expressed genes indicated the upregulation of the genes related to innate immune responses, and cell death pathways, and the downregulation of genes for photosynthesis, plastid organization, and primary and secondary metabolic pathways in the inducer-treated i-amiCHLI plants.

Impaired Expression of Chloroplast HSP90C Chaperone Activates Plant Defense Responses with a Possible Link to a Disease-Symptom-Like Phenotype.

RNA-seq analysis of a transgenic tobacco plant, i-hpHSP90C, in which chloroplast HSP90C genes can be silenced in an artificially inducible manner resulting in the development of chlorosis, revealed the up- and downregulation of 2746 and 3490 genes, respectively. Gene ontology analysis of these differentially expressed genes indicated the upregulation of ROS-responsive genes; the activation of the innate immunity and cell death pathways; and the downregulation of genes involved in photosynthesis, plastid organization, and cell cycle. Cell death was confirmed by trypan blue staining and electrolyte leakage assay, and the HO production was confirmed by diaminobenzidine staining.

A review of microplastics pollution in the soil and terrestrial ecosystems: A global and Bangladesh perspective.

Microplastics (MP) are a persistent and silent threat to the environment and are already considered a significant problem in aquatic environments. However, the presence of MP in soils and terrestrial ecosystems has been largely unexplored. Recent research has identified the risk of MP transfer from terrestrial agriculture to the human food chain.

Characterization of , an Emerging Fungal Pathogen Causing Blight in Hyacinth Bean ().

Stems and pods of hyacinth bean cultivated in a farmer's field in Gazipur District, Bangladesh, were found rotted in nearly 5% hyacinth bean plants. A fungus having fluffy mycelium and large sclerotia was isolated from affected tissues. Combined results of morphological, molecular and pathological analyses identified the fungus as (Lib) de Bary.

Isolation and Identification of Plant Growth Promoting Rhizobacteria from Cucumber Rhizosphere and Their Effect on Plant Growth Promotion and Disease Suppression.

Plant growth promoting rhizobacteria (PGPR) are the rhizosphere bacteria that may be utilized to augment plant growth and suppress plant diseases. The objectives of this study were to identify and characterize PGPR indigenous to cucumber rhizosphere in Bangladesh, and to evaluate their ability to suppress Phytophthora crown rot in cucumber. A total of 66 isolates were isolated, out of which 10 (PPB1, PPB2, PPB3, PPB4, PPB5, PPB8, PPB9, PPB10, PPB11, and PPB12) were selected based on their in vitro plant growth promoting attributes and antagonism of phytopathogens.
