Introduction to Epigenetics Science

Introduction to Epigenetics Science What is epigenetics? The term epigenetic is often used to describe a variety of unexpected patterns of gene regulation. Chemical modifications of chromosomal DNA and/or structures that change the pattern of gene expression without altering the DNA sequence. Epigenetics:  Any process that alters gene activity without changing the DNA sequence and leads to modifications that can be transmitted to daughter cells Or, Gene functions can be altered by more than just change in DNA sequence. Epigenetic trait: Is a stably heritable phenotype resulting from changes in a chromosome without alterations in the DNA  sequence. Importance of […]

Endangered Plants

All over the world, we always known about the endangered animals, but what are the most endangered plants? They might not be as stirring or attractive as animals, but they are just as important to the ecosystem and humanity depends on that ecosystem. In this articles we’ll talking about the most threatened plants today. Almost all this kinds are classed as critically endangered by the International Union for Conservation of Nature (IUCN). These plants inhabit some of the most unreachable, distant parts of our planet. They are threatened by habitat destruction, illegal collection, poaching, and competition with invading species. Some of […]

Magnetic Technology and Agricultural Sector

Among the stresses in agricultural sector worldwide, the increase of soil and water salinity is considered the major stress. This is particularly emerging in developing countries like MENA region. The chronic water shortage in the Middle East North Africa (MENA) region is a perplexing issue, undoubtedly because various operational sectors. The use of magnetically treated water is an important factor in achieving sustainable development in the agricultural sector. It improves plant production, reduces fertilizer use, and increase water irrigation efficiency, Also, use of magnetically treated irrigation water reduced soil pH but increased soil E C and available P in different […]

MiniReview: Simmondsia chinensis Jojoba tree

Jojoba tree Waleed F. Abobatta Horticulture Research Institute, Agriculture Research Center, Egypt. Abstract: This review presents general information about Hohoba commonly as jojoba. It is the sole species of the family Simmondsiaceae. Jojoba plants have currently received exceptional attention, since, its seeds contain a unique liquid wax commonly called jojoba oil, that is very similar to that obtained from Whale sperm. Jojoba is considered a promising crop for arid and marginal areas; the plant also has probable value in combatting desertification and soil degradation in dry areas. Although the plant is known for its high-temperature and high-salinity tolerance growth ability, […]

Buddha Hands Fruit

Buddha Hands Fruit Citrus medica var. sarcodactylus This lemon like citron (Citrus medica var. sarcodactylus) is not usually eaten fresh, (although the rind may be candied and is sometimes used for zest), but it’s fragrant and said to have some medical qualities. It is said that the fragrance of a single fruit can perfume a room for weeks. The Origin:                                     The origin of this kind of citron is commonly traced back to the Far East, probably northeastern  India  or China, where most domesticated citrus fruits originate. Description:       […]

Reuse waste water and Green cities development

Reuse waste water and Green cities development Introduction:                                     In nature, water (as energy) is neither formed nor destroyed but is converted from one form to another . Only about 1% of global water occurs as liquid freshwater. More than 98% of the freshwater occurs as groundwater, while less than 2% is available in streams and lakes, so the liquid freshwater is a finite and limited resource. The increasing scarcity of water in the world along with rapid population increase in urban areas gives […]

A valuable plant production from Marginal Lands

A VALUABLE PLANT PRODUCTION FROM MARGINAL LANDS Summery Marginal land considered as a died land which need high cost to reclaim regarding many reasons like hard climate. Unfortunately, there are wide marginal areas in MENA region for different reasons like high salinity, drought, high temperature and meal nutrition. However, there are certain high-value types of plants that fit it this environment, and Jojoba seedling is on the top of these plants. Jojoba Simmondsia chinensis (Link) Schneider is a precious, drought resistant shrub that is adapted to the marginal land and dry area, and offers promise for agriculture in harsh environments […]

Jojoba A key to sustainable development in marginal lands

Jojoba A key to sustainable development in marginal lands Summery Planting jojoba in marginal lands considered a sustainable approach to the environment and its resources. Marginal lands are particularly defenseless to a range of problems associated with desertification; wide areas of the world’s dry lands can be characterized as marginal. Jojoba {Simmondsia chinensis (Link) Schneider} considered a crop that consume less water than other crops, hot summers resist and great salinity tolerance, which can grow in many semi-arid regions of the world, would not require the use of chemical pesticides that pollute the environment, also, offers promise for agriculture in […]

Bio Fuel Trees

Bio Fuel Trees In the last decades there are more attention of the seriousness of pollution of excessive use of fossil fuels, which causes a lot of environmental hazards , now there are direction to production of new types of  bio fuel less harmful to the environment. Produce bio fuel from agricultural oils as a fuel in diesel engines has been proposed as an alternative to diesel from fossil resources. Vegetable oils are produced from numerous oil seed crops, like jojoba and Jatropha trees.  jojoba oil appears to be promising scope for cultivation in arid and semi-arid areas, The […]

Role of Nanotechnology in Horticulture production enhancement

Nanotechnology is a newly initial field in recent decades on a commercial scale, in the same time increasing pollution rates in various agricultural products is a serious problem need quickly solving to increase exporting our agriculture products, Nano materials promise many stimulating changes to enhance different crop production and fruit quality. We must manage to increase production efficiency of different horticulture crops, increased soil vitality and decreased costs as possible and decreasing the pollution, with using novel sciences such as nanotechnology in products, could be counted as the best solution to this problem. Also, Nano materials is using as antifungal […]
