Characterization of Infection Arrest Mutants of Medicago Truncatula and Genetic Mapping of Their Respective Genes.

Description: In response to compatible rhizobia, leguminous plants develop unique plant organs, root nodules, in which rhizobia fix nitrogen into ammonia. During nodule invasion, the rhizobia gain access to newly divided cells, the nodule primordia, in the root inner cortex through plant-derived cellulose tubes called infection threads. Infection threads begin in curled root hairs and bring rhizobia into the root crossing several cell layers in the process. Ultimately the rhizobia are deposited within nodul… more

A Drop of Oil

Description: Many Christian writers point to God through their fiction without openly evangelizing. The images their words evoke lift their secular and religious readers' heads, for God is reflected in their use of language, the emotions they describe, and the actions of their characters. The preface and short stories in this collection aim to show that God's presence can be felt even when people are suffering due to human decisions and mistakes. He is with His creations in the midst of their pain to impart… more

Functionalization and characterization of porous low-κ dielectrics.

Description: The incorporation of fluorine into SiO2 has been shown to reduce the dielectric constant of the existing materials by reducing the electrical polarizability. However, the incorporation of fluorine has also been shown to decrease film stability. Therefore, new efforts have been made to find different ways to further decrease the relative dielectric constant value of the existing low-k materials. One way to reduce the dielectric constant is by decreasing its density. This reduces the amount of p… more

Molecular and biochemical characterization of phospholipase D in cotton (Gossypium hirsutum L) seedlings.

Description: N-Acylethanolamines (NAEs) are enriched in seed-derived tissues and are believed to be formed from the membrane phospholipid, N-acylphosphatidylethanolamine (NAPE) via the action of phospholipase D (PLD). In an effort to identify a functional NAPE-PLD in cotton seeds and seedlings, we have screened a cotton seedling cDNA (cotyledon mRNA from 48 h dark grown seedlings) library with a 1.2 kb tobacco partial cDNA fragment encoding the middle third of a putative PLDβ/γ (genbank accession, AF195614)… more
