Summary: Xanthomonas phaseoli pv. manihotis (Xpm) causing Cassava Bacterial Blight (CBB) may have dramatic effects on plant growth and crop production, while X. cassavae (Xc) causing Cassava Bacterial Necrosis has limited impacts on plant vigor and crop production. Limited data on Xc means the main focus is on Xpm and CBB in this review.

Summary: This study characterized the TALE diversity in Colombian strains of Xpm, identifying 13 novel variants and a functional variant that activates a susceptibility gene in cassava. Through transcriptomics and prediction analyses, several TALE-targeted candidate genes were selected, along with two potential cases of functional convergence. This research provides new insights into potential TALE targets in the Xpm-cassava interaction, which could be crucial for defining the infection outcome.

Summary: This study evaluates the assessment of cassava clones in Nigeria through variety trials and identifies the most suitable model for analyzing the data. The findings suggest that the Factor Analytic Model of Order 3 (FA3) is the most effective in understanding genotype-by-environment interaction (GEI) in multi-environment field trials.

Summary: This study characterized Latin American cassava germplasm using an integrated genomic and metabolomic approach. Classification based on genotyping correlated with the leaf metabolome and revealed adaption to specific eco-geographical environments. The root metabolome did not relate to genotypic clustering, suggesting different spatial regulation. These findings enhance community resources and provide valuable insight into breeding materials related to combating food security.

Summary: This study reveals that ethanol priming enhances drought tolerance in cassava by regulating stomatal closure. Ethanol pretreatment induces abscisic acid (ABA) accumulation and stomatal closure, resulting in reduced transpiration rate and increased water content and starch accumulation in leaves during drought stress. The transcriptomic analysis shows that ethanol pretreatment upregulates ABA signaling-related genes and stress response genes, and delays the upregulation of drought-inducible genes. These findings suggest that ethanol pretreatment improves drought avoidance in cassava through activation of the ABA signaling pathway, protein folding-related response, and changes in sugar and starch metabolism.

Summary: Thermoplastic cassava starch films were synthesized using different ratios of native cassava starch, glycerol, and cardanol-based plasticizers. The concentration of cardanol-based co-plasticizers greatly influenced the mechanical properties, with significant increases in modulus and tensile strength, as well as a decrease in elongation. The moisture content and thermal resistance were also affected by the co-plasticizer content.

Summary: This study investigated the potential of extracting starch from cassava peel and bagasse as non-edible sources. The study developed an extraction method to maximize starch extraction and compared the properties of the extracted starch with commercial cassava starch. The results showed that cassava peel starch had a significantly higher yield than bagasse starch, and the extracted starch from both sources exhibited similar morphology and functional groups.

Summary: This study provides a comprehensive analysis of the TIFY family genes in cassava and their roles in plant stress responses. The characterization of these genes and their phylogenetic relationships, as well as the prediction of protein interaction networks, offer valuable insights into their evolution and functions. The validation of gene expression patterns in response to different stress conditions further adds to our understanding of the TIFY family genes in cassava.

Summary: Cassava is an important tropical tuber crop worldwide, and its production is affected by a key disease called cassava bacterial blight. Genetic diversity analysis revealed the presence of copper-resistant gene clusters CopLAB and xmeRSA in X. phaseoli pv. manihotis strains, which were highly conserved across different geographic regions.

Summary: This article discusses the importance of cassava globally, particularly in Africa and South Africa. Due to its climate-resilient nature, cassava has become a popular crop among farming communities in frost-free areas of South Africa. A multidisciplinary research program has been established at the Agricultural Research Council of South Africa to promote progress in cassava breeding and genetic analysis.

Summary: This study evaluated the physical properties of cassava foam powder produced from white and yellow cassava by foam mat drying, and compared them with cassava pulp powder. The flow properties, rehydration kinetics, and adsorption isotherm of the powders were analyzed. The results showed that the foam powders had different true densities, flow properties, and rehydration kinetics compared to cassava pulp powder.

Summary: Solid-state fermentation (SSF) is a promising technology for producing value-added products from cassava. It offers advantages such as lower costs, reduced water usage, and higher product yields. SSF can enhance the nutritional value of cassava-based products and minimize waste by utilizing cassava waste as a substrate. However, optimizing process conditions and developing cost-effective production processes are essential for successful commercialization.
