Evaluation of improved Cassava (Manihot esculanta Crantz) varieties in mid land area of South Omo Zone, Ethiopia

The nature of apomixis in cassava (Manihot esculentum, Crantz).

Apomixis in cassava is formed by aposporic embryo sacs which arise from cells in nucellus or from cells in the sexual embryo sac. There is an association between sterility and apomixis. It seems that sterility caused by defected meioses triggers a specific gene for exhibiting apomixis. This apomictic mechanism is favoured by natural selection since it offers an escape from lethality and provide...

Unveiling the Micronome of Cassava (Manihot esculenta Crantz)

MicroRNAs (miRNAs) are an important class of endogenous non-coding single-stranded small RNAs (21-24 nt in length), which serve as post-transcriptional negative regulators of gene expression in plants. Despite the economic importance of Manihot esculenta Crantz (cassava) only 153 putative cassava miRNAs (from multiple germplasm) are available to date in miRBase (Version 21), and identification ...

Anatomical alterations due to polyploidy in cassava, Manihot esculenta Crantz.

Information on anatomical structure is needed by breeders working on improvement for drought tolerance. For studying the effect of polyploidy on cassava anatomy and its significance to tolerance to drought, we induced a polyploidy type of a selected clone (UnB 530) by applying an aqueous solution of 0.2% colchicine on lateral buds for a period of 12 h. The stem identified as tetraploid was prop...

Flour from three local varieties of Cassava (Manihot Esculenta Crantz): Physico- chemical properties, bread making quality and sensory evaluation

Factors affecting cyanide content in cassava (Manihot esculenta Crantz) [Faktor yang mempengaruhi kandungan sianida dalam ubi kayu (Manihot esculenta Crantz)]

Concern over poisoning as a result of eating cassava roots or shoots has led to these studies to determine factors which lead to high cyanide content in these tissues and how detoxification can be carried out. Plant age or stage of development does not seem to have a clear influence on root or shoot cyanide content. Genetic control on cyanide content seems significant as varieties may be identi...
