Abstract: The Brazilian sugarcane sector has increased the adoption of conservation practices based both on mechanized harvest without burning and on the use of biological nitrogen fixation (BNF) to improve crop sustainability. However, there is no information about the impact of these practices on sugarcane diseases. This study aims at investigating the effect of conservation practices on the incidence and severity of spontaneous sugarcane diseases, considering soil tillage, planting season, residue maintenance, and sources of nitrogenous fertilizers. Two experiments were conducted, being one during the cane-plant cycle and the other carried out throughout the sugarcane cycle until the second ratoon. The simultaneous occurrences of ring spot, caused by Leptosphaeria sacchari Breda de Haan, and red rot leaf infection, caused by Colletotrichum falcatum Went, were the only diseases observed in the experiments regardless of the conservation practices. The use of reduced tillage, conventional tillage, and non-tillage as well as the planting season and the depth of the sugarcane trash layer did not influence the severity of the diseases. However, BNF reduced the severity of foliar diseases in the first and second ratoons. The overall disease severity affected the dry biomass of sugarcane in the first ratoon. The results can assist disease management strategies considering the new scenario of sugarcane production in Brazil. |

Carotenoid-Protein content in cassava storage root (CSR) is low but variable, and characterization of this variability is lacking. Accumulation of carotenoids occurs in chromoplast and depends on a broad class of proteins named carotenoid associated proteins (CAP), lipids and the biosynthesis of carotenoids. Twenty-nine landraces and progeny of 200 individuals were accessed for CAP and carotenoid content varied in two ways. First, related to landrace diversity, total buffer extractable proteins (TBEP), buffer insoluble proteins (BIP) and total carotenoid and ?-carotene content were assessed. Significant differences were observed in the tested genotypes. Secondly, analyses related to storage root tissue age were assessed by TBEP. This showed protein content decreased and total carotenoid content increased as secondary growth proceeds. Further carotenoid-proteins complex (CPC) identified in carotenoid contrasting landraces showed different proteins profile in SDS-PAGE with proteins size of 18 and 33 kDa in low carotenoid (IAC12.829) and 18-20-30-33 kDa in a high total carotenoid landrace (Cas74.1). Progeny analysis for TBEP and total carotenoid content confirmed the interdependence of carotenoid-proteins association by correlation analysis, estimated heritability of individual traits and grouping clones for carotenoid-proteins content. Results allow us to conclude that: natural carotenoid-protein content varies due to differential genetic background and storage root tissue age; carotenoid-protein complex showed variation in protein and carotenoid types; estimated heritability of proteins and carotenoids traits showed different values. The establishment of a genetic component allows future strategies including traditional breeding and the use of induced mutations to create novel variation for the nutritional improvement of cassava tubers.
