Transfer cells are ubiquitous plant cells that play an important role in plant development as well as in responses to biotic and abiotic stresses. They are highly specialized and differentiated cells playing a central role in the acquisition, distribution and exchange of nutrients. Their unique structural traits are characterized by augmented ingrowths of invaginated secondary wall material, un...

Cysteine proteinases from the fruit and latex of plants, such as papaya, pineapple and fig, have previously been shown to have substantial anthelmintic efficacy, in vitro and in vivo, against a range of animal parasitic nematodes. In this paper, we describe the in vitro effects of these plant extracts against 2 sedentary plant parasitic nematodes of the genera Meloidogyne and Globodera. All the...

When nematodes invade and subsequently migrate within plant roots, they generate cell wall fragments (in the form of oligogalacturonides; OGs) that can act as damage-associated molecular patterns and activate host defence responses. However, the molecular mechanisms mediating damage responses in plant-nematode interactions remain unexplored. Here, we characterized the role of a group of cell wa...

The primary source of plant parasitic nematodes in irrigation waterways in the Columbia Basin Project of eastern Washington is irrigation runoff returned into the irrigation system. This has contributed to the rapid spread of plant parasitic nematodes observed during eight years of study.

Cucumber plants play an important role in economical field in Egypt. But they are infected by plant parasitic nematodes that leading to losses cucumber yield. This study attempted to construct more efficient bacterial strains may be able to controlling nematodes, as well as, maintenance the soil fertility using molecular biology method via induced protoplast fusion between different strains of ...

It is somewhat ironic that an important finding concerned with cellulose biosynthesis in higher plants (1) appeared just before the paper in this issue of the Proceedings by Smant et al. (2) describing genes from a plant parasitic nematode that encode proteins that degrade cellulose. Cellulose is the most abundant polymer on the planet and is an essential component of the plant cell wall. Altho...
