Abstract:
Meloiodgyne incognita, one of the most aggressive plant parasitic nematodes species on potato in South Africa, belongs to a group of plant parasitic nematodes commonly known as root knot nematodes (RKN). This group of nematodes is widely distributed throughout the world. Meloidogyne spp. cause major economic losses to important crops such as potato and therefore decrease their market value in many countries across the world. The second stage juveniles are the only mobile and infective phase of the root knot nematode. As they infect host roots, they create wounds that can be used by other plant

Over the years, potato production in South Africa has been affected by, among other factors, diseases and plant parasitic nematodes particularly root-knot nematodes (Meloidogyne spp.). In infected potato fields, root-knot nematodes cause great damage to the crop leading to substantial losses in yield and compromised produce quality. The direct a

Erwinia soft rot is a widespread disease destructive to numerous important crop plants. Damage to plants is primarily due to celldegrading enzymes (CDEs) secreted by the bacteria.

Much has been learned in vitro about the molecular genetics of CDEs in the past decade; however, little is known about their expression in plantae To study expression of genes for these enzymes during pathogen

Abstract:
Physicochemical properties of flours and starches isolated from tubers and roots commercially available in Australia and traditionally produced in Indonesia were investigated in this study. The results showed that these flours and starches may be utilized in certain food applications. Raw starchy materials from Australia included taro, yam, and sweet potato. Due to its narrow particle size distribution (1-64 μm), taro flour would be better suited in applications which require improved binding and reduced breakability.
