(2014), calcium strengthens the cell wall structure by interacting with pectic acid to form calcium
pectate. Calcium
pectate, in turn, reduces the cell wall porosity by limiting the transport of larger molecules, restricting sugar gain (MAURO et al., 2016).
The increased resistance in tissues with high levels of calcium has been attributed to decreased maceration owing to calcium deposition in the cell wall
pectate and structural enhancement of cell wall integrity [7, 8, 23].
The secretions, from nematode dorsal and sub-ventral glands, facilitate the migration of the nematode through induced expression levels of plant genes encoding for the cell wall degrading and modifying enzymes such as cellulases, expansins, glucanases and
pectate lyases (Wyss and Grundler 1992; Golinowski et al., 1996; Smant et al., 1998; Goellner et al., 2001; Wieczorek et al., 2006; Abad et al., 2008).

silicate, sodium chloride and less than 40% redwing sugar, wherein the eight catalysts are a protease, an amylase, a cellulase, a lipase, a mannose, a
pectate lyase, a manganese centered catalyst, and a cobalt centered catalyst.
The [beta]-Hex, a cell wall enzyme, cleaves the terminal N-acetyl-D-hexosamine residues and generates the paucimannosidic N-glycans present in most plant glycoproteins which in turn downregulate the genes that encode for certain cell wall degrading proteins, such as pectin methylesterase, glucan endo-1,3-[beta]-D-glucosidase, [beta]-1,3-glucanase, endoxyloglucan transferase, pectinesterase, expansin, pectinacetylesterase, agalactosidase,
pectate lyase, (1-4)-[beta]-mannan endohydrolase, and [beta]-galactosidase [10].

In the February 1973 "Kickshaws" [1] we find the seven-letter sequence
PECTATE, which at the time was the longest known English word which can be written entirely with Cyrillic-looking characters.
The natural pectin methyl esterase gradually converts the soluble pectin in the juice to pectic acid, which combines with the calcium to form an insoluble calcium
pectate gel.
Magnesium (Mg) is an important element for plant, it is a component of chlorophyl and magnesium
pectate, is essential for formation of carotenoids and required by a large number of enzymes connected with phosphate transfer [26].
Pectate lyase formulation suited for low to medium temperature eco-souring at neutral pH, resulting in improved fabric quality (soft er, bulkier hand), lower fabric weight loss, enhanced absorbency and improved fabric dyeability compared to conventional scouring.
LGT between eukaryotes and prokaryotes has been documented through transcriptome and genome analysis of plant parasitic nematodes (Scholl and Bird, 2011) with genes encoding glucanases and
pectate lyases that are absent in other animals but are similar to those of rhizosphere bacteria.
