Mutation in the Arabidopsis thaliana QUASIMODO 1 gene (QUA1), which encodes a putative glycosyltransferase, reduces cell wall pectin content and cell adhesion. Suspension-cultured calli were generated from roots of wild-type (wt) and qua1-1 A. thaliana plants. The altered cell adhesion phenotype of the qua1-1 plant was also found with its suspension-cultured calli. Cell walls of both wt and qua...

Pectins from Araçá (Psidium cattleianum Sabine) fruit pulp were extracted, purified and isolated, obtaining the Purified Pectin (APP) under its sodium form. Yield was found 3.5% w/w of initial dried material. From titration, monosaccharide analysis after total hydrolysis 1H HSQC NMR analyses, it established that pectins are formed long galacturonic acid blocks (HG) partially methylated (degree ...

Species of Abies trees are considered susceptible to the effects diseases and pests. As a result complex biotic impact Ussuri Polygraph (Polygraphus proximus Blandford) area potential drying Siberian fir (Abies sibirica Ledeb) stands up 10 million hectares. Trees corrupted by root pathogens center desiccation, from where pathological decay spreads, so also there arise an urgent issue disposal b...
