La famille des palmiers dattiers (Phoenix dactylifera L.) : Arecaceae) est l'une des plus anciennes cultures fruitières des régions arides de la péninsule arabique, de l'Afrique du Nord et du Moyen-Orient. La zone d'origine la plus probable du palmier-dattier se situe dans ou près de l'actuel pays d'Irak, mais la culture des dattes s'est répandue dans de nombreux pays dès l'Antiquité. Les dattes constituent une source d'alimentation et de revenus importante pour les populations locales du Moyen-Orient et de l'Afrique du Nord, et jouent un rôle significatif dans l'économie, la...

Die Dattelpalme (Phoenix dactylifera L.) Familie: Arecaceae) ist eine der ältesten Obstkulturen, die in den Trockengebieten der Arabischen Halbinsel, Nordafrikas und des Nahen Ostens angebaut wird. Das wahrscheinlichste Ursprungsgebiet der Dattelpalme liegt im oder in der Nähe des heutigen Irak, aber der Dattelanbau verbreitete sich seit der Antike in vielen Ländern. Datteln sind eine wichtige Nahrungs- und Einkommensquelle für die lokale Bevölkerung im Nahen Osten und in Nordafrika und spielen eine wichtige Rolle in Wirtschaft, Gesellschaft und Umwelt in diesen Gebieten. Datteln dienen...

Crown gall is a plant tumor incited on dicotyledonous plants by infection with a bacterium, Agrobacterium tumefaciens. During this process, a portion of a large plasmid contained in the bacterial cell is transferred and incorporated into the genome of the host plant cell. The transferred plasmid DNA, the T-DNA, carries information for products that either control or code for the synthesis of plant hormones. The increased level of phytohormones causes the transformed cells to escape from host control mechanisms and proliferate limitlessly, thus causing a tumor. The T-DNA also contains...

Stem cell therapies are particularly important for addressing the challenges arise from the body's restricted capacity to repair and rejuvenate injured tissues and metabolic processes after experiencing acute or chronic damage. The origin of stem cell therapy can be traced back to 1991 when Caplan introduced the concept. Caplan theorized that the manipulation of stem cells in a controlled laboratory setting could lead to the significant development of specific tissues. Among the various types of stem cells, Mesenchymal stem cells (MSC) are particularly favored for therapeutic applications...

Plant defense against herbivory or host-plant resistance is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Many plants produce secondary metabolites, known as allelochemicals, that influence the behavior, growth, or survival of herbivores. These chemical defenses can act as repellents or toxins to herbivores or reduce plant digestibility. Another defensive strategy of plants is changing their attractiveness. Plants can sense being touched, and they can respond with strategies to defend against herbivores. Plants...

Climate change impacts our society in many different ways. Drought can harm food production and human health. Flooding can lead to spread of disease, death, and damage ecosystems and infrastructure. Human health issues that result from drought, flooding, and other weather conditions increase the death rate, change food availability, and limit how much a worker can get done, and ultimately the productivity of our economy. Climate change affects everyone, but the impacts are uneven across the country and around the world. Even within one community, climate change can affect one neighborhood or...
