PA-TM-RING proteins have an N-terminal protease-associated domain, a
structure found in numerous proteases and implicated in protein binding,
and C-terminal RING finger and PEST domains. Homologous proteins
include GRAIL (gene related to anergy in leukocytes), which controls
T-cell anergy, and AtRMR1 (receptor homology region-transmembrane
domain-RING-H2 motif protein), a plant protein storage vacuole sorting
The past decade has seen the field of proteomics expand from a highly technical endeavor to a widely utilized technique. The objective of this book is to highlight the ways in which proteomics is currently being employed to address issues in the biological sciences. Although there have been significant advances in techniques involving the utilization of proteomics in biology, fundamental approaches involving basic sample visualization and protein identification still represent the principle techniques used by the vast majority of researchers to solve problems in biology.
The genomics revolution of the past decade has greatly enhanced our understanding of
the genetic composition of living organisms including many plant species of economic
importance. Complete genomic sequences of Arabidopsis and several major crops, together
with high-throughput technologies for analyses of transcripts, proteins and mutants, provide
the basis for understanding the relationship between genes, proteins and phenotypes.
PLANT CELLS, UNLIKE ANIMAL CELLS, are surrounded by a relatively thin but mechanically strong cell wall. This wall consists of a complex mixture of polysaccharides and other polymers that are secreted by the cell and are assembled into an organized network linked together by both covalent and noncovalent bonds. Plant cell walls also contain structural proteins, enzymes, phenolic polymers, and other materials that modify the wall’s physical and chemical characteristics.
"Bioactive Food Peptides in Health and Disease" highlights recent developments on bioactive food peptides for the promotion of human health and the prevention/management of chronic diseases. The book provides a comprehensive revision of bioactive peptides obtained from both animal and plant food sources. Aspects related to their bioactivity, mechanism of action, and bioavailability are extensively described along the different chapters.
PLANT BIOLOGISTS MAY BE FORGIVEN for taking abiding satisfaction in the fact that Mendel’s classic studies on the role of heritable factors in development were carried out on a flowering plant: the garden pea. The heritable factors that Mendel discovered, which control such characters as flower color, flower position, pod shape, stem length, seed color, and seed shape, came to be called genes. Genes are the DNA sequences that encode the RNA molecules directly involved in making the enzymes and structural proteins of the cell.
Non coding endogenous RNAs were first discovered in the last decade of the previous
century. These new discoveries changed our views of the transcriptome landscape of
plant genomes and paradigms of the regulation of gene expression. With the beginning
of this century, we have witnessed an explosion of studies on small regulatory
RNAs that has yielded a basic understanding of the many types of small RNAs in
diverse eukaryotic species and how they are functioning as RNA–protein complexes
along the RNA silencing pathways.
A novel plant protein isolated from the underground bulbs of
Scadoxus multiflorus, xylanase and a-amylase inhibitor protein (XAIP),
inhibits two structurally and functionally unrelated enzymes: xylanase and
a-amylase. The mature protein contains 272 amino acid residues which
show sequence identities of 48% to the plant chitinase hevamine and 36%
to xylanase inhibitor protein-I, a double-headed inhibitor of GH10 and
Protein N-myristoylation plays key roles in various cellular functions in
eukaryotic organisms. To clarify the relationship between the efficiency of
protein N-myristoylation and the amino acid sequence of the substrate in
plants, we have applied a wheat germ cell-free translation system with high
protein productivity to examine the N-myristoylation of various wild-type
and mutant forms ofArabidopsis thalianaproteins.
The protein disulfide isomerase is known to play important roles in the
folding of nascent polypeptides and in the formation of disulfide bonds in
the endoplasmic reticulum (ER). In this study, we cloned a gene of a novel
protein disulfide isomerase family from soybean leaf (Glycine maxL. Mer-rill. cv Jack) mRNA.
Tiger shrimp (P. monodon) and marine fishes are common fish cultured in coastal area of Vietnam. The study on nutrition for such species has not much when compared to freshwater fish species. Trash fish is the traditional feed for marine cultured fish and tiger shrimp in semi-intensive system. The supply is not stable in term of quality and quantity. Moreover, the price has increased. Therefore, finding alternative feed for trash fish is very important and crucial issues Using pellet feed in which fishmeal was replaced by plant protein that started in 90’s decade.

They use geological and distribution
data on the island’s 1,284 plant genera and more than 2,000 endemic plant taxa to
identify 19 biomes there, and they describe complex conservation challenges. The next
chapter by Benny Chan and Pei-Fen Lee explores the biogeography of the barnacles of
Taiwan, relating taxon distributions to coastal geomorphology and the complex array
of oceanic currents around the island. Global climate changes in ocean water
temperature may permit southerly, warmwater taxa to expand northward, invading
habitat presently occupied by coldwater taxa....
Chlorophyll fluorescence represents an intrinsic signal emitted by plants
that can be employed to monitor their physiological state including changes of the
photosynthetic apparatus, developmental processes of leaves, state of health, stress events,
stress tolerance, and also to detect diseases or nutrient deficiency of plants. In particular, the
application of laser induced chlorophyll fluorescence spectroscopy has drawn much attention
recently owing to the non-invasive and nondestructive nature of the technique (Svanberg,
1995; Lang & Lichtenthaler, 1991; Chappelle et al., 1984)....
Corn is the major cereal crop of the U.S. and the second most important cereal crop worldwide.
The diversity of potential uses for corn was realized by the Native Americans prior to the first
voyage of Columbus. Today, corn production in the U.S. provides feed, food, and a resource for
many unique industrial and commercial products. The potential to enhance use of corn for specialty
purposes based on existing uses, and develop new products to meet the needs of future generations,
provides the plant breeder/plant scientist with unique challenges.
Cells are tiny building blocks that make up all living things. Cells are so small that you need a microscope to see them.
This is the control centre of the cell. It contains chromosomes with DNA instructions for all the cell’s activities, including instructions to make new cells. This is a jelly like substance, in which many of the cell’s activities, e.g. respiration and protein synthesis occur. This is a thin skin around the cell. It is selectivelt permeable, controlling what goes in and out of the cell....
The use of alternative fuels to displace coal reduces reliance on fossil fuels, reduces
emissions of carbon dioxide (CO2) and other pollutants, and contributes to long-term cost
savings for cement plants. Further, due to their high burning temperatures, cement kilns
are well-suited for accepting and efficiently utilizing a wide range of wastes that can
present a disposal challenge.
This report begins with an overview of the types of alternative fuels used in cement kilns,
focusing on energy and environmental considerations.
Information about plant genetic diversity is necessary for the development of appropriate
strategies in conservation biology as well as in many other applied fields. From a basic
evolutionary standpoint, genetic diversity is assumed to be crucial for the evolutionary
potential of a species. Research programs that aim to investigate population structure
provide evolutionary insights into the demographic patterns of diverse organisms (Milligan
et al., 1994).
