  • 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 receptor.

  • 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.

  • 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 GH11 xylanases.

  • 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.

  • 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).

  • Flow cytometry in our studies contributes to better understanding of prokaryotic roles in the Adriatic Sea as a separate ecosystem and as an important part of the Mediterranean Sea. Studies of prokaryotic community by flow cytometry in the eastern part of Adriatic Sea started in year 2003. The first studies were carried out for purposes of comparing two direct counting methods for bacterioplankton (Šantić et al., 2007). The accuracy of epifluorescence microscopy (EM) was assessed against direct counts made by flow cytometry (FCM).
