background aloe vera l. is an important pharmaceutical plant from which several medicinal and cosmetic compounds are extracted. aloe is naturally propagated through offset, which is a slow and expensive labor cost method with low economical income. objectives in this study, the effect of different media on shoot proliferation of the shoot tip of aloe vera l. was investigated. materials and meth...

Plant cryopreservation is useful for long term storage of clonal germplasm and endangered species. Clonally propagated crops which produce recalcitrant seeds cannot be easily conserved using conventional methods. Preservation plants in vitro limited to two years not ideal a very time. The need conserve plant genetic resources through techniques mitigate the effects climate change such as extinc...

a study was conducted to investigate the effect of follicular size (small,

Plants are a potential source of a large number of valuable secondary metabolites. In vitro cultures are being considered as an alternative to agricultural processes for studying valuable secondary metabolites. In this way, nutritive factors are important parameters influencing the production of these compounds in plants. Effects of nitrate concentrations (KNO3) on the production of two tropane...

BACKGROUND Efficient transformation and regeneration methods are a priority for successful application of genetic engineering to vegetative propagated plants such as grape. The current methods for the production of transgenic grape plants are based on Agrobacterium-mediated transformation followed by regeneration from embryogenic callus. However, grape embryogenic calli are laborious to establi...

BACKGROUND Plant acclimation is a highly complex process, which cannot be fully understood by analysis at any one specific level (i.e. subcellular, cellular or whole plant scale). Various soft-computing techniques, such as neural networks or fuzzy logic, were designed to analyze complex multivariate data sets and might be used to model large such multiscale data sets in plant biology. METHODO...
