          Abstract

          Micropropagation of Passiflora species and its hybrids may play an important role in the production of healthy and disease-free plants which can be a source of medicinal herbal products, nutritional fruits and ornamental flowers. The rapid multiplication of elite plants to obtain pharmacognostic material, containing valuable flavonoid C-glycosides, is possible by usingcontrolled in vitro conditions, constituents of the medium and the interactions of plant growth regulators (1-naphtaleneacetic acid, benzyladenine, gibberellin GA3,kinetin, indole-3-acetyl-L-aspartic acid, indole-3-butyric acid, thidiazuron) and influencing various chemical additives (silver nitrate, coconut water, activated charcoal). Investigations of specific requirements during stages of micropropagation, such as the establishment of primary cultures (including type of explants, age of donor plant), shoot multiplication (by direct and indirect organogenesis and embryogenesis), rooting and acclimatization of regenerated plants are summarized in this review. The following species were recently studied for micropropagation: P. alata, P. caerulea, P. cincinnata, P. edulis, P. foetida, P. setacea, P. suberosa. It seems that for awide range of applications of in vitro clones of Passiflora, interdisciplinary studies including genetic and phytochemical aspects are needed.

          Plant disease: a threat to global food security.

          A vast number of plant pathogens from viroids of a few hundred nucleotides to higher plants cause diseases in our crops. Their effects range from mild symptoms to catastrophes in which large areas planted to food crops are destroyed. Catastrophic plant disease exacerbates the current deficit of food supply in which at least 800 million people are inadequately fed. Plant pathogens are difficult to control because their populations are variable in time, space, and genotype. Most insidiously, they evolve, often overcoming the resistance that may have been the hard-won achievement of the plant breeder. In order to combat the losses they cause, it is necessary to define the problem and seek remedies. At the biological level, the requirements are for the speedy and accurate identification of the causal organism, accurate estimates of the severity of disease and its effect on yield, and identification of its virulence mechanisms. Disease may then be minimized by the reduction of the pathogen's inoculum, inhibition of its virulence mechanisms, and promotion of genetic diversity in the crop. Conventional plant breeding for resistance has an important role to play that can now be facilitated by marker-assisted selection. There is also a role for transgenic modification with genes that confer resistance. At the political level, there is a need to acknowledge that plant diseases threaten our food supplies and to devote adequate resources to their control.

            The Chemical Composition and Biological Properties of Coconut ( Cocos nucifera L.) Water

            Coconut water (coconut liquid endosperm), with its many applications, is one of the world’s most versatile natural product. This refreshing beverage is consumed worldwide as it is nutritious and beneficial for health. There is increasing scientific evidence that supports the role of coconut water in health and medicinal applications. Coconut water is traditionally used as a growth supplement in plant tissue culture/micropropagation. The wide applications of coconut water can be justified by its unique chemical composition of sugars, vitamins, minerals, amino acids and phytohormones. This review attempts to summarise and evaluate the chemical composition and biological properties of coconut water.
