Correlation of genetic variation among wild Trigonella foenum-graecum L. accessions with their antioxidant potential status

E. A. Haliem and Al-Huqail, A. A., Correlation of genetic variation among wild Trigonella foenum-graecum L. accessions with their antioxidant potential status, vol. 13, pp. 10464-10481, 2014.

In this study, we analyzed the correlation between genetic variation based on random amplified polymorphic DNA (RAPD), acid phosphatase, and glutamate-oxaloacetate transaminase isozymes, and amino acid composition with the antioxidant potential status of 7 wild Trigonella foenum-graecum L. accessions collected from diverse ecogeographical regions. RAPD revealed that 90 DNA products had highly polymorphism value (94.12%) based on band numbers, with sizes ranging from 50-2100 base pairs, and band intensity.

Amino acid profile in cassava and its interspecific hybrid

N. M. A. Nassar and Sousa, M. V., Amino acid profile in cassava and its interspecific hybrid, vol. 6, pp. 292-297, 2007.

Cassava roots have a low-protein content (0.7-2%). Amino acids such as lysine and methionine are also low, and some research reports have indicated the absence of methionine. The amino acid profiles of a common cassava cultivar and an interspecific hybrid, namely ICB 300, were determined using the computerized amino acid analyzer Hitachi L-8500. The interspecific hybrid has 10 times more lysine and 3 times more methionine than the common cassava cultivar: lysine content was 0.010 g per 100 g in the common cassava cultivar while it reached 0.098 in the interspecific hybrid.

Cassava genetic resources and their utilization for breeding of the crop

Wild cassava relatives are perennials and vary in growth pattern from nearly acaulescent subshrubs to small trees. They have been used as a source of useful characters such as high protein content, apomixis, resistance to mealybug and mosaic disease, and tolerance to drought. Indigenous clones are a potential source of β-carotene and lycopene. Apomixis genes have been transferred to the crop successfully through interspecific hybridization, and apomictic clones arising from these hybrids are now being grown at the Universidade de Brasília.
