  • Công nghệ chuyển gen: là đưa một đoạn DNA ngoại lai vào gen của cơ thể đa bào, sau đó DNA ngoại lai này sẽ có mặt ở hầu hết các tế bào và được truyền lại cho thế hệ sau. Gen chuyển:(transgene) là gen ngoại lai được chuyển từ một cơ thể sang một cơ thể mới bằng kỹ thuật di truyền. GMP (genetically modified plant): thực vật biến đổi gen

  • The wide geographical distribution of the rice plant ( Oryza sativa L.) and its long history of cultivation in Asian countries have led to the development of a great diversity of varietal types. Similarly, workers in various rice-growing countries use different terms to designate identical morphological and physiological characters, agronomic traits, gene symbols, and cultural practices. Whereas varietal diversity in germ plasm is desired in rice breeding, variations in nomenclature hinder scientific communication among the workers.

  • The genomics revolution of the past decade has greatly enhanced our understanding of the genetic composition of living organisms including many plant species of economic importance. Complete genomic sequences of Arabidopsis and several major crops, together with high-throughput technologies for analyses of transcripts, proteins and mutants, provide the basis for understanding the relationship between genes, proteins and phenotypes.

  • Property, plant and equipment is carried at cost less accumulated depreciation. Assets manufactured by the Company include direct manufacturing costs, production overheads and interest charges incurred during the construction period. Government grants are deducted from the cost of the related asset. Depreciation is calculated using the straight-line method over the expected economic life of the asset. Depreciation of special tooling costs is based on the expected future economic benefit of these tools.

  • PLANT BIOLOGISTS MAY BE FORGIVEN for taking abiding satisfaction in the fact that Mendel’s classic studies on the role of heritable factors in development were carried out on a flowering plant: the garden pea. The heritable factors that Mendel discovered, which control such characters as flower color, flower position, pod shape, stem length, seed color, and seed shape, came to be called genes. Genes are the DNA sequences that encode the RNA molecules directly involved in making the enzymes and structural proteins of the cell.

  • This book is about the conservation of genetic diversity of wild plants in situ in their natural surroundings, primarily in existing protected areas but also outside conventional protected areas. A lot of effort has been dedicated to conserving plant biodiversity, but most of this has focused on rare plant communities or individual species threatened with extinction.

  • Despite a variety of processes and the availability of raw-material sources, the widespread utilisation of annual plants in pulping has not been technically or economically feasible in Western countries due to the lack of a simple and environmentally efficient pulping method and the problems associated with raw material storage and logistics. An ideal non-wood pulping process is simple and environmentally efficient and can be applied on a small scale.

  • Non coding endogenous RNAs were first discovered in the last decade of the previous century. These new discoveries changed our views of the transcriptome landscape of plant genomes and paradigms of the regulation of gene expression. With the beginning of this century, we have witnessed an explosion of studies on small regulatory RNAs that has yielded a basic understanding of the many types of small RNAs in diverse eukaryotic species and how they are functioning as RNA–protein complexes along the RNA silencing pathways.

  • Although the main consideration of policy must be the reduction in pollution at source, there has been an increasing recognition that the biosphere is an important sink for many pollutants, with plant canopies being considered more effective than other land uses. Thus, the biosphere provides benefits additional to those associated directly with their aesthetic and wildlife characteristics. Plants facilitate the uptake, transport and assimilation or decomposition of many gaseous and particulate pollutants.

  • MicroRNAs (miRNAs) have been proven to play important roles at the post-transcriptional level in animals and plants. To investigate clustering patterns and specific sequence characteristics in the flanking regions of plant miRNA genes, we performed genome-wide analyses ofArabidopsis thaliana, Populus trichocarpa, Oryza sativaand Sorghum bicolor.

  • DNA methylation affects important developmental processes in both plants and animals. The process of methylation of cytosines at C-5 is catalysed by DNA methyltransferases (MTases), which are highly conserved, both struc-turally and functionally, in eukaryotes. In this study, we identified and characterized cytosine DNA MTase genes that are activated with the onset of reproductive development in rice.

  • Coffee plant is one of the most important industrial crops, and the two popular cultivars, Coffea arabica and Coffea canephora, contribute to the production of almost all coffee beans around the world. Traditional breeding could be used to develop new coffee cultivars with a higher productivity under these harsh conditions, and a biotechnological approach can also be used to improve coffee plants in a relatively short period of time.

  • Yellow stem borer has been identified as a major insect pest of deepwater rice, causing severe yield losses. Bt gene(s) from Bacillus thuringiensis have been proven very effective in pest resistance program. The use of transgenic plants expressing Bt gene(s) is now occupied effective approach to control insect infestation. We have successfully introduced a synthetic cryIA(b) gene into embryogenic calli of a deepwater indica rice variety, Vaidehi, by using the biolistic method of transformation.

  • Traditional breeding could be used to develop new coffee cultivars with a higher productivity under these harsh conditions, and a biotechnological approach can also be used to improve coffee plants in a relatively short period of time. To develop new coffee cultivars via a biotechnological approach, it is necessary to discover potential candidate genes and determine their functions in coffee plants.
