Genotypic variation of traits related to quality of cassava roots using affinity propagation algorithm Scientia Agricola
Oliveira,Eder Jorge de; Santana,Fernanda Alves; Oliveira,Luciana Alves de; Santos,Vanderlei da Silva.
The conservation, sustainable evaluation and use of cassava (Manihot esculenta Crantz) genetic resources are essential to the development of new commercial varieties. This study aimed to evaluate the quality of cassava roots and to estimate genetic variation and clustering in cassava germplasm using the Affinity Propagation algorithm (AP), which is based on the concept of "message passing" between data points. AP finds "exemplars" of each group and members of the input set representative of clusters. The genotypic data of 474 cassava accessions were evaluated over a period of two years for starch yield (StYi), root dry matter (DMC), amylose content (AML), and the level of cyanogenic compounds (CyC). The AP algorithm enabled the formation of nine diversity...

Partition of proteins in aqueous two-phase systems based on Cashew-nut tree gum and poly(ethylene glycol) BABT
Sarubbo,Leonie Asfora; Oliveira,Luciana Alves de; Porto,Ana Lúcia Figueiredo; Campos-Takaki,Galba Maria de; Tambourgi,Elias Basile.
The partitioning of two proteins, bovine serum albumin (BSA) and trypsin was studied in an aqueous poly(ethylene glycol)(PEG)- Cashew-nut tree gum system. The phase diagram was provided for Cashew-nut tree gum and PEG molecular weight of 1500 at two different temperatures. The influence of several parameters including concentrations of polymers, pH, salt addition and temperature on the partitioning of these proteins were investigated.. The results of this research demonstrated the importance of the protein characteristics for partitioning in aqueous biphasic system.

Physico-chemical characterization of banana varieties resistant to black leaf streak disease for industrial purposes Ciência Rural
Godoy,Rossana Catie Bueno de; Waszczynskj,Nina; Santana,Fernanda Alves; Silva,Sebastião de Oliveira e; Oliveira,Luciana Alves de; Santos,Guilherme Godoy dos.
ABSTRACT: Cultivated bananas have very low genetic diversity making them vulnerable to diseases such as black-Sigatoka leaf spot. However, the decision to adopt a new banana variety needs to be based on a robust evaluation of agronomical and physical-chemical characteristics. Here, we characterize new banana varieties resistant to black-Sigatoka leaf spot and compare them to the most widely used traditional variety (Grand Naine). Each variety was evaluated for a range of physic-chemical attributes associated with industrial processing and flavor: pH, TTA, TSS/TTA, total sugars, reducing sugars and non-reducing sugars, humidity, total solids and yield. The Thap Maeo variety had the highest potential as a substitute for the Grand Naine variety, having higher...
