Abstract Sustainability challenges, e. However, the transition from a fossil fuel-based economy to a bio-based economy requires the exploitation of scientific innovations and step changes in the infrastructure of chemical industry. Biorefineries have been extensively investigated for biofuel production from first and second generation feedstocks, whereas some research activities have been conducted on production of biochemical and biopolymers from renewable resources. Techno-economic evaluation of diverse technologies for production of biofuels and biochemical is a crucial step for decision making in the development of bio-economy. This contribution focuses on the economic studies carried out on biorefineries converting sugarcane bagasse, due to its availability and importance in the South African context, into value-added products. Recent studies on biofuel production via biochemical pathway, e. In addition, an overview on the production of biopolymers such as polyl-lactic acid and bio-based monomers, i.

As can be seen in the pheromone chapter of Francke and Schulz, acetals have been known originally as aggregation pheromones of bark beetles Chapter 4.

Musth periods get longer as males age. Secretions containing high concentration of frontalin 19 at racemic ratios attracted follicular-phase females, whereas the secretions repulsed males as well as luteal phase and pregnant females. The importance of the enantiomeric composition of frontalin 19 in the behavior of Asian elephants was observed only after the advent of enantioselective chiral gas chromatography GC.

Genes in the major histocompatibility complex MHC , known for their role in immune recognition and transplantation success, are involved in modulating mate choice in mice and perhaps also in humans.

For this study, previously synthesized mice pheromone components 20 and as well as newly synthesized ones 22 and were employed. In the case of mice, Mus musculus, higher levels of 1R,5S,7R -dehydro-exo-brevicomin 20 Figure 5 Structures of pheromone components of male Asian elephants and mice. The addition of 23 had no effect at all. Accordingly, it is established in the case of mice that semiochemicals control the mate selection process.

This will enable us to resolve many problems that remain unraveled. Chemical ecology is an interdisciplinary science between chemistry and biology. No one can be an expert in both the areas unless one wants to remain superficial. Acknowledgments I wish to thank Dr. Tashiro for his help. Glossary kairomone A kairomone is a chemical substance produced and released by a living organism that benefits the receiver and disadvantages the donor.

The kairomone improves the fitness of the recipient and in this respect differs from an allomone. References 1. Mori, Ed.

In this chapter, auxins, gibberellins GAs , cytokinins, abscisic acid, brassinosteroids BRs , jasmonic acid-related compounds, and ethylene are described as established plant hormones, while polyamines and phenolic compounds are not included, according to the definition used in the previous edition of the book Comprehensive Natural Products Chemistry.

The hormones of each living species are often characteristic of that species, reflecting the characteristics of its life phenomena. The characteristics of plant hormones can be related, at least partially, to the peculiar growth phenomena known as developmental plasticity, where a plant keeps forming new organs and tissues throughout its life cycle.

New growth is frequently associated with sites where plant hormones are synthesized and this can be summarized in the following points. The number of known plant hormones is fewer than the number of mammalian hormones. The number of plant hormones has increased since the publication of the previous edition of the book Comprehensive Natural Products Chemistry in ; BRs are added to the plant hormone group, and the group of jasmonic acid-related compounds, a group of peptides, and strigolactone are also included.

Plant hormones appear to be ubiquitous, that is, they are present in all higher plants and many are also present in lower plants, and even in fungi and bacteria. This universality of plant hormones is remarkable. The effects of plant hormones are quite complex, one plant hormone often having a wide range of effects.

However, the various phenomena observed when a plant hormone is applied do not always establish that the plant hormone is directly causing the effect in untreated plants. Some effects of a plant hormone may be direct while others are indirect, with the site of action being quite remote from the location of the end effect.

Additionally, there is evidence for rather complex interactions among the various plant hormones. Although plants do not have a nervous system, they must perceive environmental signals and use them for regulation of growth and organ development. The response systems in plants do not involve a biological architecture similar to a nervous system; nevertheless, they employ small molecule signals with remarkable structural similarities to the neurotransmitters.

The basic program for growth and development is recorded in Plant Hormones 13 the genome and modified by environmental signals. This modification by the environment yielding developmental plasticity, as reflected in changes in plant growth and development, is one of the clear differences from mammalian hormones, and plant hormones are considered to act as mediators.

Light, temperature, and moisture are particular environmental signals, and these affect the biosynthesis, catabolism, and translocation of plant hormones. Sensitivity to plant hormones is also likely to be affected by environmental conditions. For example, the effect of GA on shoot elongation is greater under a low light intensity than under a high light intensity. Although progress in plant hormone research had often traditionally trailed that of mammalian hormones, progress during the last decade has been particularly noticeable.

The biosynthetic pathways of most plant hormones have been determined, and the genes encoding many of the enzymes that catalyze the biosynthetic steps have been cloned. However, the exact steps in the biosynthesis of auxin indoleacetic acid still remain obscure in part because of the apparent existence of redundant pathways for its production. The progress in molecular biology has enabled the relationship between the phenomena to be determined, and the responsible genes and the mechanisms regulating their expression have been extensively studied.

The microarray technique enables the genes responsive to each plant hormone to be identified and the signal transduction pathways of the plant hormones to be clarified. Recent extensive studies have elucidated significant and clear examples of the cross talk occurring between plant hormones. Opande, G.
