A cDNA encoding a polygalacturonase-inhibitor-like protein (PGIP) was isolated from cotton flower cDNA library. The cDNA, designated GhPS1 (GenBank accession No. ABO47744), encodes a protein with 370 amino acids that shares high similarity with the known plant PGIPs. Fluorescent microscopy indicated that GhPS1 protein localizes on the cell membranes as well as in cytoplasm. Real-time quantitati...

The phytohormone ethylene is essential for senescence in many fruits and flowers. In the biosynthesis of ethylene in plants, the conversion of S-adenosyl methionine (SAM) to 1-aminocyclopropane1-carboxylic acid (ACC) and the conversion of ACC to ethylene are catalyzed by ACC synthase (ACS) and ACC oxidase (ACO), respectively (Adams and Yang, 1979). Using a cDNA clone representing carnation ACO ...

One of the most dynamic research and application areas of neural networks is classification. In this paper, the use of matlab coding for simulation of backpropagation neural network for classification of Iris dataset is demonstrated. Fisher’s Iris data base collected from uci repository is used. The data set contains 3 classes of 50 instances each, where each class refers to a type of iris plan...

We address the unsolved problem of unfolding prismatoids in a new context, viewing a “topless prismatoid” as a convex patch—a polyhedral subset of the surface of a convex polyhedron homeomorphic to a disk. We show that several natural strategies for unfolding a prismatoid can fail, but obtain a positive result for “petal unfolding” topless prismatoids. We also show that the natural extension to...

The Arabidopsis SUPERMAN (SUP) gene encodes a C2H2 type zinc finger protein that is required for maintaining the boundaries between stamens and carpels, and for regulating development of ovule outer integument. Orthologs of SUP have been characterized in bisexual flowers as well as dioecious species, but it remains elusive in monoecious plants with unisexual flowers on the same individual. Here...

We describe an algorithm for automatically segmenting flowers in colour photographs. This is a challenging problem because of the sheer variety of flower classes, the intra-class variability, the variation within a particular flower, and the variability of imaging conditions – lighting, pose, foreshortening etc. The method couples two models – a colour model for foreground and background, and a...

During route discovery of mobile ad hoc network, broadcasting of route request and route reply packets are the essential operations for finding the path between two ends. In such situations, intermediate node which may or may not belongs will participate in route discovery process, update routing table and rebroadcast the route discovery packets again to its neighboring nodes. Finally optimal p...

The molecular conformation of Ca2+/calmodulin-dependent protein kinase II (CaM kinase II) from the rat forebrain and cerebellum was studied by means of EM using a quick-freezing technique. Each molecule appeared to be composed of two kinds of particles, with one larger central particle and smaller peripheral particles and had shapes resembling that of a flower with 8 or 10 "petals". A favorable...

Polariton condensates are macroscopic quantum states formed by half-matter half-light quasiparticles, thus connecting the phenomena of atomic Bose-Einstein condensation, superfluidity, and photon lasing. Here we report the spontaneous formation of such condensates in programmable potential landscapes generated by two concentric circles of light. The imposed geometry supports the emergence of an...
