Activated charcoal has a very fine network of pores with large inner surface area on which
many substances can be adsorbed. Activated charcoal is often used in tissue culture to …

Trees are an integral part of human life, and a vital component of biodiversity. Forest trees in
particular are renewable sources of food, fodder, fuel wood, timber and other valuable non …

In this study, we examined the regulation by putrescine, spermidine and spermine of nitric
oxide (NO) biosynthesis in Arabidopsis thaliana seedlings. Using a fluorimetric method …

Somatic embryogenesis, the in vitro developmental program by which somatic cells are
reprogrammed to undergo cellular and molecular changes that make them competent to …

Somatic embryogenesis is the capacity of somatic or non-sexual (ie all cells other than the
gametes) plant cells to form embryos by a process resembling zygotic embryogenesis. It …

It is estimated that there are more than 270 000 plant species in existence and
approximately 34 000, or 1 in 8, of these are considered endangered (IUCN, 1998) …

Dioscorea rotundata, commonly known as white yam, is an important staple food crop widely
cultivated in West Africa and provides food security to millions of people. Genetic …

The aim of this work was to study morphological and biochemical aspects during zygotic
embryogenesis in O. catharinensis, by measuring changes in the endogenous …

In this study we examined the effect of polyamines (PAs) putrescine (Put), spermidine (Spd)
and spermine (Spm) on growth, morphology evolution, endogenous PAs levels and nitric …

In the present work, we investigate the association of SERK gene homolog expression,
polyamines (PAs) and amino acids related to putrescine synthesis (arginine and ornithine) …
