Speech Title: Alleviation of some environmental stress using plant growth rhizobacteria (PGPR) in Egypt
Abstract: Environmental stress causes great losses in crop production where abiotic factors like soil salinity, drought and extreme temperature constitute the most fatal problems. Abiotic stress tolerance of plants is a complex process involving modifications at many levels. Abiotic stress is considered as the principal cause of crop yield loss worldwide, it has been reduced average yields of major food and cash crops by more than 50%. Thereby, causing the most fatal economic losses in agriculture. Because it often induces several morphological, physiological, biochemical and molecular changes that negatively affect the overall plant performance. Primed plants can be enhance tolerance to stress by certain chemicals or biological agents, e.g. plant growth promoting rhizobacteria (PGPR). These microbes can promote plant growth by regulating nutritional and hormonal balance, producing plant growth regulators, solubilizing nutrients and inducing resistance against plant pathogens. Induced systemic tolerance (IST) has been achieved in many drought stressed plants after inoculation with several PGPR strains. Egypt is one of the countries that suffer severe salinity problems. For example, 33% of the cultivated land, which comprises only 3% of total land area in Egypt, is already salinized. Climate changes will lead to a decline in the productivity of Egypt's major agricultural crops such as wheat by 18%, rice by 11% and soybeans by 28% due to high temperatures and expected shortage of available water resources that affecting plant productivity.
Sinking and salinity of many lowland agricultural lands in the delta due to rising sea level. High temperatures will increase insects and diseases that cause damage to agricultural crops. This will result in a decline in agricultural production by 8%. The main concern facing the scientists is how to invest the known methods and subsequent data into useful practices for sustainable crop production how to use them to reduce the incidence of plant diseases, the input of chemical fertilization, and the emission of the greenhouse gases and how to enhance plant performance especially with ongoing climate change. PGPR can provide a potential and inexpensive management tool that help plants to grow and combat the problems of drought and other climate related problems. In Egypt many researchers are working on alleviation the environmental stress by PGPR. Here, we will present some of positive results further.
