Nematodes Associated with Apple (malus Pumila Mill.) in Balochistan, Pakistan
Sixty rhizosphere soil samples of apple seedlings and rootstock were collected from six nurseries of Khuzdar and Kalat districts of Balochistan. Six different plant nematodes were found associated with the seedlings and rootstock. The most predominant nematode was Xiphinema americanum, whereas the nematode found from a single locality was Tylenchus butteus. A matrix of similarities with respect...
متن کاملCell Wall Metabolism in Ripening Fruit: IV. Characterization of the Pectic Polysaccharides Solubilized during Softening of ;Bartlett' Pear Fruit.
Fractionation of pectic polysaccharides from the juice of ripening ;Bartlett' pears (Pyrus communis) gave two general types of polyuronides. The major type was a homogalacturonan (HGA) whose molecular weight decreased upon ripening. The other type comprised heteropolymers composed of various amounts of arabinose, rhamnose, and galactose. Treatment of the major arabinose-containing heteropolymer...
متن کاملThe structure, function, and biosynthesis of plant cell wall pectic polysaccharides.
Plant cell walls consist of carbohydrate, protein, and aromatic compounds and are essential to the proper growth and development of plants. The carbohydrate components make up approximately 90% of the primary wall, and are critical to wall function. There is a diversity of polysaccharides that make up the wall and that are classified as one of three types: cellulose, hemicellulose, or pectin. T...
متن کاملRelationship between Indole-3-Acetic Acid Levels in Apple (Malus pumila Mill) Rootstocks Cultured in Vitro and Adventitious Root Formation in the Presence of Indole-3-Butyric Acid.
In vitro rooting response and indole-3-acetic acid (IAA) levels were examined in two genetically related dwarfing apple (Malus pumila Mill) rootstocks. M.26 and M.9 were cultured in vitro using Linsmaier-Skoog medium supplemented with benzyladenine (BA), indole-3-butyric acid (IBA), and 1,3,5-trihydroxybenzoic acid (PG). Rooting response was tested in Lepoivre medium supplemented with IBA and P...
متن کاملPurification and some properties of chlorogenic acid oxidase from apple (Malus pumila).
Chlorogenic acid oxidase was extensively purified to homogeneity from apple flesh (Malus pumila cv. Fuji). The enzyme was purified 470-fold, with a total yield close to 70% from the plastid fraction by ammonium sulfate precipitation, gel filtration and ion-exchange chromatography. The molecular weight was determined to be 65,000 by both SDS-PAGE and gel filtration chromatography. The optimum pH...
