Gene stacking is the process of addition of two or more gene of interest into a single plant. The combination or stacking of different traits or genes in plants is rapidly gaining popularity in biotech crop production. The new evolved trait is known as stacked trait and the crop is known as biotech stacked or simply stacked. This can be accomplished in many ways, one of which is gene pyramiding. Biotech stacks give crops a larger genetic and agronomic boost, allowing them to perform better in challenging farming situations. Biotech stacks are designed to increase productivity by overcoming biotic and abiotic challenges like as insect pests, diseases, weeds, and environmental stress. This review will explain about the gene stacking principle, the need for biotech stacking, and the many gene stacking methods.

Farmers are highly dependent upon agrochemicals to boost crop production through soil fertilization and and insect pests, pathogens, parasites, and weeds management . However, contentious application of agrochemicals on the farm has aggravated residual accumulation and has become problematic for environmental safety besides causing disease to humans and other animals. Thus, the analysis of chemical residues from the environment is vital for policymakers and communities. Mostly, chemists were devoted to analyzing the existing contaminants from different sources by using highly sophisticated chromatographic equipment, although it is time taking, laborious, costly, and that required well-trained professionals. However, biosensors are more important to analyze chemical contaminants from different samples using various bioreporters integrated with electrochemical and optical transducers. Microbes are metabolically diverse, amenable for genetic engineering, cost effective in culturing, and tolerant to diverse conditions. Thus, microbial biosensor is capturing attention and becoming more effective for environmental monitoring. Therefore, this review assessed the implication of microbial biosensors for pesticide detection and the role of genetic engineering for strain improvement.

High Yielding Varieties

Bangladesh is essentially self-sufficient in rice as a result of the successful adoption of new high-yielding varieties and irrigated summer production over traditional deep-water cultivation practices. The sustainability of the cropping system depends on farmers adopting integrated pest management (IPM) practices in preference to relying solely on insecticides for pest and disease control. Yet insecticide consumption in rice is increasing, in common with other crop-production systems in Bangladesh. It is probably only the poor economic returns from rice cultivation that prevent more widespread use of pesticides. Enlightened agrochemical companies such as Syngenta Bangladesh Limited have recognized that insecticide use in rice should be discouraged, and promote IPM options through their farmer field school (FFS) programme. This paper describes the results of a collaborative project to assist Syngenta to develop and incorporate mass trapping with sex pheromones into their FFS programme as an environmentally benign method of controlling the predominant insect pests of rice, stem borers.

Vegetable cultivation is a promising economic activity, and vegetable consumption is important for human health due to the high nutritional content of vegetables. Vegetables are rich in vitamins, minerals, dietary fiber, and several phytochemical compounds. However, the production of vegetables is insufficient to meet the demand of the ever-increasing population. Plant-growth-promoting rhizobacteria (PGPR) facilitate the growth and production of vegetable crops by acquiring nutrients, producing phytohormones, and protecting them from various detrimental effects. In this review, we highlight well-developed and cutting-edge findings focusing on the role of a PGPR-based bioinoculant formulation in enhancing vegetable crop production. We also discuss the role of PGPR in promoting vegetable crop growth and resisting the adverse effects arising from various abiotic (drought, salinity, heat, heavy metals) and biotic (fungi, bacteria, nematodes, and insect pests) stresses.

Resumo. A cultura do feijoeiro pode ser infestada por insetos que afetam a produção antes e após a colheita, tendo como estimativa de perdas causadas nos rendimentos pelas pragas variando de 33 a 86%. Dentre essas pragas a mosca-branca Bemisia tabaci (Genn.) Autor merece destaque. Esta ocasiona danos diretos decorrentes de sua alimentação e indiretos que ocorrem por meio da excreção açucarada de honeydew ou “mela” e simbiose com a fumagina. No entanto, o dano mais sério causado pela B. tabaci é a transmissão de viroses como o mosaico-dourado-do-feijoeiro, provocando perdas econômicas que podem variar de 30% a 100%. Desse modo, o objetivo do presente estudo é disponibilizar informações a respeito de aspectos importantes de B. tabaci, como: histórico e distribuição geográfica, bioecologia e dinâmica populacional, plantas hospedeiras, métodos de controle adotados, dentre outros, a fim de se fornecer subsídios para futuras pesquisas sobre a mosca-branca em feijão.Whitefly Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae) in common beans: General characteristics, bioecology, and methods of controlAbstract. Common bean plants are infested by insects, which can ultimately affect the crop production before and after harvest, with estimated losses ranging from 33 to 86%. Among the insect pests infesting the common beans the whitefly Bemisia tabaci (Genn.) stands out. This species cause direct injury by feeding on the plants and indirect injury by excreting sugary honeydew that is after colonized by the sooty mold. In addition, the most serious damage caused by B. tabaci is the transmission of virus diseases, especially the common bean golden mosaic, responsible for economic losses varying from 30 to 100%. This review aims at providing information on important aspects of B. tabaci including its geographical distribution, bioecology, population dynamics, host plants, and methods of pest control. We expect that this review can provide valuable subsidies for future studies on the whitefly in common beans.

Elevated Co2 And Temperature

The most important factor that affects the crop production in terms of nutritional content of foliar plants is the global climate change. Herbivore’s growth, development, survival and geographical distribution all are determined by elevated CO2 and temperature. The interactions between herbivores and plants have changed due to increasing level of CO2 and temperature. The effect of high CO2 and temperature on grain legume plant which change in to plant physiology (e.g., nutritional content, foliage biomass) and how it change in herbivory metabolism rate and food consumption rate. Plant injury is determined by two factors viz. resistance and tolerance and both are influenced by greater CO2 and temperature. Legumes are an important source of food and feed in the form of proteins and also improve the soil environment. The repercussions of the abiotic factors mentioned above needs discussion among the scientific community. We may able to limit the negative repercussions of stated factors in future breeding projects by harnessing the practical favourable impacts and by including such influences of elevated CO2 and temperature on pulses productivity. The extensive research is necessary to overcome the negative effects of high CO2 and temperature on insect-plant interaction.

Despite decades of research, healthcare information systems have been characterised by cost over-runs, poor specifications and lack of user uptake. A new approach is required which provides organisations with a reason to invest in this type of software. W Edwards Deming argues that quality is not an entity but derives from using feedback, iteratively to seek improvement to processes, in order to increase productivity and to make better use of resources. The authors propose that supporting this form of quality assurance (QA) using information systems (IS) has the potential to deliver a return on investment. An object-oriented analysis, where healthcare is viewed as the delivery of interdependent processes to which Deming’s form of QA is applied, results in a class model of data types that has some useful characteristics. It is able to store data about medical and nonmedical events; to save descriptions of procedures and to represent the QA process itself. With software based on the model, organisations will have a memory of previous attempts at making improvements as well as data about feedback from patients and staff to drive future change. A critical research in information systems (CRIS) analysis of this model proposes a number of criticisms deriving from theories about rationality; concepts of technology; politics and hidden agendas, as well as the social consequences of technology. The view that QA is a standardised, ongoing conversation about the important characteristics of a process pre-empts many of these counter arguments. The CRIS critique also highlights the need to ensure that development is in harmony with the needs of the many stakeholders in healthcare IS. These concepts lead to new directions in healthcare IS research. The class model needs to be tested against clinical and non-clinical use-cases for its viability not only as support for QA but also as an electronic patient record. A standard terminology is required for processes and for how objects from the model should be used to represent them. The model predicts that user interfaces will have to collect more detailed data than hitherto. Also use of the software should be tested in controlled trials to demonstrate whether the required improvements in quality not only benefit the patient but also the organisations managing their care.

AbstractThe most useful and practical strategy available for reducing variability of net farm income is ascertained. Of the many risk management tools presently available, five of the most commonly used are simultaneously incorporated in an empirically tested model. Quadratic programming provides the basis for decisionmaking in risk management wherein expected utility is assumed to be a function of the mean and variance of net income. Results demonstrate that farmers can reduce production and price risks when a combination strategy including a diversified crop production plan and participation in the futures market and the Federal Crop Insurance Program (FCIP) is implemented.
