RNAi Technology for Crop Development

RNA interference (RNAi) is a natural cellular process that regulates gene expression by a highly precise mechanism of sequence-directed gene silencing at the translational stage by degrading certain messenger RNAs or inhibiting translation. By mimicking this natural process of gene regulation RNAi technique has been established for therapeutic application both »

DNA Methylation for Plant Development

To present, genome-wide approaches to analyzing DNA methylation have yielded a vast amount of information on its general characteristics across the plant genome. Cytosine DNA methylation is a fundamental heritable epigenetic change seen in all major eukaryotic groups and is involved in essential cellular functions such DNA structural integrity, transposable »

Sequencing Crop Genomes: A Gateway to Improve Tropical Agriculture

Agricultural development in the tropics lags behind development in the temperate latitudes due to the lack of advanced technology, and various biotic and abiotic factors. To cope with the increasing demand for food and other plant-based products, improved crop varieties have to be developed. To breed improved varieties, a better »

Spirulina: Food for Future

Spirulina (Arthrospira platensis) belonging to the family Spirulinaceae is a free-floating filamentous microalgae to the class Cyanobacteria. Spirulina is an ecologically sound, nutrient-rich super-food that is grown all around the world as a dietary supplement. Spirulina is considered as the “Food of the Future” that will effectively tackle the existing »

Next-Generation Sequencing: A Breakthrough to Unexplored Genomics

Next-generation sequencing (NGS) is a massively parallel sequencing technology that offers ultra-high throughput, scalability, and speed. The technology is used to determine the order of nucleotides in entire genomes or targeted regions of DNA or RNA. NGS technology has fundamentally changed the kinds of questions scientists can ask and answer. »

Plant Innate Immunity: Self Defense Mechanism against pathogen

To protect against pathogens plants have an innate immune system. One of the defense mechanisms, Pattern Triggered Immunity (PTI), prevents non-adapted microbes from infecting plants. The surface pattern recognition receptors (PRRs) firstly recognize pathogen associated molecular patterns (PAMPs). PAMP recognition stimulates ion transportation through plasma membrane and enhances activation of »

Seed Vigour Testing

Seed vigour, a single concept reflecting several characters, determines the seed quality and uniform emergence potential of plants in the field under variable range of environments. Seed vigour does not reflect a specific property of a seed or seed lot but is still a concept. Several factors like genetic constitution, »

Marker Assisted Selection: An Intervention of Modern Science

The development of DNA (or molecular) markers has irreversibly changed the disciplines of plant genetics and plant breeding. While there are several applications of DNA markers in the case of breeding, the most promising for cultivar development is called marker assisted selection (MAS). MAS is a process in which a »

Hybrid Purity Tests: Connecting Parental Lines with the Hybrids

Hybrid seed is a seed produced by cross-pollinating plants in a controlled environment. Hybrids are bred to improve the characteristics of the resulting plants, such as better yield, greater uniformity, improved vigor, color, disease resistance, and so forth. Today, hybrid seed is predominant in agriculture and home gardening, and is »

Effect of Cold Storage Conditions on Properties of Potato Tubers

Post-harvest processing is important for making potatoes available for a longer period in the market and keeping the losses at a minimum. Different factors are responsible for affecting the storage of potatoes in storehouses. Potatoes should be stored at different temperatures according to their intended purposes. Low temperature is better »
