Recent years have seen tremendous progress in unraveling the
molecular basis of different plant-microbe interactions. Knowledge
has accumulated on the mecha nisms of the microbial infection of
plants, which can lead to either disease or resistance. The
mechanisms developed by plants to interact with microbes, whether
viruses, bacteria, or fungi, involve events that can lead to
symbiotic association or to disease or tumor formation. Cell death
caused by pathogen infection has been of great interest for many
years because of its association with plant resistance. There
appear to be two types of plant cell death associated with pathogen
infection, a rapid hypersensitive cell death localized at the site
of infection during an incompatible interaction between a resistant
plant and an avirulent pathogen, and a slow, normosensitive plant
cell death that spreads beyond the site of infection during some
compatible interactions involving a susceptible plant and a
virulent, necrogenic pathogen. Plants possess a number of defense
mechanisms against infection, such as (i) production of
phytoalexin, (ii) formation of hydrolases, (iii) accumulation of
hydroxyproline-rich glycoprotein and lignin deposition, (iv)
production of pathogen-related proteins, (v) produc tion of
oligosaccharides, jasmonic acid, and various other phenolic
substances, and (vi) production of toxin-metabolizing enzymes.
Based on these observations, insertion of a single suitable gene in
a particular plant has yielded promising results in imparting
resistance against specific infection or disease. It appears that a
signal received after microbe infection triggers different signal
transduction pathways.
Here, researchers review the latest breakthroughs in protein
research. Their contributions explore emerging principles and
techniques and survey important classes of proteins that will play
key roles in the field's future. Articles examine the possibility
of a Boltzman-like distribution in protein substructures, the new
technique of Raman spectroscopy, and compact intermediate states of
protein folding. This well-illustrated volume also features
coverage of proteins that bind nucleic acids.
Eminent researchers provide broad coverage of plant molecular
biology and genetic engineering, detailing technological advances
in plant cell transformation and responses. This state-of-the-art
text includes coverage of molecular action of plant growth hormone,
signal transduction, light mediated expression of genes, and
genetic engineering of crop plants and trees.
The heterogeneity of topics...is very ambitious, and the result is,
overall, successful because of the high quality of the individual
contributions....highly recommended.' -American Scientist, from a
review of a previous volume Volume 26 examines the emerging areas
of signal transduction based on myoinositol phosphates and Ca2+
while focusing on plant and animal responses. Chapters explore
synthesis, separation, and identification of different inositol
phosphates.
From being to becoming important, myo-inositol and its derivatives
including phosphoinositides and phosphoinositols involved in
diversi?ed functions in wide varieties of cells overcoming its
insigni?cant role had to wait more than a century. Myo-inositol,
infact, is the oldest known inositol and it was isolated from
muscle as early as 1850 and phytin (Inositol hexakis phosphate)
from plants by Pfeffer in 1872. Since then, interest in inositols
and their derivatives varied as the methodology of isolation and
puri?cation of the stereoisomers of inositol and their derivatives
advanced. Phosphoinositides were ?rst isolated from brain in 1949
by Folch and their structure was established in 1961 by Ballou and
his coworkers. After the compilation of scattered publications on
cyclitols by Posternak (1965), proceedings of the conference on
cyclitols and phosphoinositides under the supervision of
Hoffmann-Ostenhof, were p- lished in 1969. Similar proceedings of
the second conference on the same s- ject edited by Wells and
Eisenberg Jr was published in 1978. In that meeting at the
concluding session Hawthorne remarked "persued deeply enough p-
haps even myoinositol could be mirror to the whole universe." This
is now infact the scenario on the research on inositol and their
phosphoderivatives. Finally a comprehensive information covering
the aspects of chemistry, b- chemistry and physiology of inositols
and their phosphoderivatives in a book entitled Inositol Phosphates
written by Cosgrove (1980) was available.
