Arabinogalactan-proteins (AGPs) are a class of highly glycosylated, hydroxyproline-rich glycoproteins that function in plant growth and development. Tomato LeAGP-1 represents a major AGP expressed in cultured cells and plants. Based on cDNA and amino acid sequence analyses along with carbohydrate

The monoclonal antibodies MAC 207 and JIM 8, recognizing arabinogalactan epitopes, were used to localize the corresponding antigenic sites in pollen tubes of Nicotiana tabacum L. grown in vitro or semi in vivo. The analysis of the immunofluorescence labelling was performed by means of confocal laser

Delayed pollination is widely used in overcoming the pre-fertilization incompatibility, but its regulatory mechanisms are unclear. When Nicotiana tabacum was cross pollinated with pollen of N. alata, the incompatibility occurring in the basal 1/4 region of the style (pollinated at anthesis: 0-d-old

Treatment of tobacco (Nicotiana tabacum) cell-suspension cultures with cryptogein, an elicitin protein from Phytophthora cryptogea, resulted in the release of a factor(s) that diffused through a 1000-D cutoff dialysis membrane and was capable of inducing sesquiterpene cyclase enzyme activity (a key

A technique has been developed for isolating embryo sacs (ESs) by enzymatic maceration. Ovules were macerated in a mixture of pectinase, cellulase and, in some cases, snailase and pectolyase Y-23. The ovular tissues were removed and the ESs were isolated in toto. Embryo sacs were isolated from both

BACKGROUND
Pectinases play an important role in plant cell wall deconstruction and have potential in diverse industries such as food, wine, animal feed, textile, paper, fuel, and others. The demand for such enzymes is increasing exponentially, as are the efforts to improve their production and to
