Reaction to Brown Rust and Presence of the Bru1 Gene in Brazil/RIDESA Sugarcane Parents BORELLA, JULIANE; PORTELA BRASILEIRO, BRUNO; DE AZEREDO, AMARO AFONSO CAMPOS; LUCIMERIS RUARO SCHUTA; Ricardo Augusto de Oliveira; João Carlos Bespalhok Filho Sugar Tech, v. 1, p. 1-8, 2021 DOI Palavra-chave: Sugarcane breeding; brown rust; Bru1 Gene Áreas do conhecimento: Ciências Biológicas; Biotecnologia; Biotecnologia Vegetal; Melhoramento de Plantas resumo ... Brown rust is an important disease that can affect the production of sugarcane in susceptible varieties. Reaction to brown rust has influenced the improvement programs in the process of clonal selection. Bru1 is one of the main resistance genes for brown rust. Therefore, the knowledge of the reaction to brown rust in the genotypes most used as parents in hybridizations would avoid crosses between susceptible genotypes. In this sense, the objectives of this work were to evaluate the reaction to brown rust in the field and the pattern of disease evolution; and the presence of the Bru1 gene in sugarcane parents of the RIDESA genetic improvement program. The experiment was carried out at the Paranavaí experimental station, where 64 genotypes were planted in a randomized block design with three replications. The severity of brown rust in the field under natural infection conditions and the presence of the Bru1 gene were evaluated. Of the 63 genotypes evaluated, 38 were classified as resistant, 13 as intermediate and 12 as susceptible. Lower values of severity of brown rust were observed in intermediate genotypes with a slow evolution of the disease when compared with susceptible parents, indicating a quantitative resistance. Bru1 was detected in 58.7% of the evaluated genotypes. The frequency of Bru1 increased from 0% in the genotypes used as parents in the 1970s to 20, 64.71 and 76% in the 1980, 1990 and 2000s, respectively.

Remarkable variability in stress responses among subtropical coastal marine teleosts BORDIN, DALIANA; Carolina Arruda de Oliveira Freire MARINE BIOLOGY, v. 168, n. 8, p. 122 2021 DOI Palavra-chave: teleosts; cortisol; estresse; osmorregulação Áreas do conhecimento: Ciências Biológicas; Fisiologia da Conservação resumo ... The relevance of the plasma cortisol response as primary stress marker in teleost fishes is well known. However, available data still refer to a low number of species, considering the huge diversity of teleosts. To improve the data base of the cortisol response in feral coastal marine teleosts, this study aimed at evaluating the response—survival and plasma cortisol, glucose, osmolality, chloride, and magnesium—of marine teleosts to the capture stress of trawling. Fish sampled were divided into three groups: dead after trawling, alive after trawling, and live fish which were kept for ~ 12 h in a tank after trawling (“overnight in tank”). Blood samples (224) of 36 species from 19 fish families have been assessed. A large variability in the cortisol response among species, within the three groups, was detected. The Brazilian silverside Atherinella brasiliensis was notable in showing essentially only very high values (> 1000 ng/mL). Some species always showed very low levels (nearly zero, e.g., most Scianidae species). Most species displayed a very broad range of values (10–1000 ng/mL), such as Eucinostomus argenteus. Inter-specific variability was also present in plasma glucose, osmolality, and ions. The response to trawling stress in wild coastal marine teleost fish species is thus extremely variable. Better knowledge about the diversity in the response of teleosts to stress contributes to fisheries management, aiming at sustainability.

Rice vinasse treatment by immobilized Synechococcus pevalekii and its effect on Dunaliella salina cultivation Guilherme Augusto Colusse; André Oliveira Santos; Jenifer Mota Rodrigues; Marcelo Calide Barga; Maria Eugênia R. Duarte; Júlio Cesar de Carvalho; Miguel Noseda BIOPROCESS AND BIOSYSTEMS ENGINEERING, v. 44, p. 1477-1490, 2021 DOI Palavra-chave: bioprocess; Rice vinasse; Bioremediation; Microalgae; cyanobacteria; Dunaliella salina Áreas do conhecimento: Ciências Biológicas; Biotecnologia resumo ... The development of new strategies in microalgal studies represents an outstanding opportunity to mitigate environmental problems coupled with biomass production at a reduced cost. Here we present a combined bioprocess for the treatment of rice vinasse using immobilized cyanobacteria Synechococcus pevalekii in alginate beads followed by the use of the treated vinasse as a culture medium for Dunaliella salina biomass production. Cyanobacterial-alginate beads showed a chlorophyll a production of 0.68 × 10–3 mg bead−1 and a total carotenoid production of 0.64 × 10–3 mg bead−1. The first step showed a decrease in nitrate (91%), total solids (29%), and ions. Addition of treated vinasse into D. salina cultivation resulted in a significant increase in cell replication of about 175% (optimized cultivation). The use of natural seawater drastically reduced the medium cost to US$4.75 per m3 and the addition of treated vinasse has the potential to reduce it even more (up to 69%). This study not only provides an insight on the use of cyanobacteria for rice vinasse treatment but also demonstrates a promising lower-cost medium for marine microalgal biomass production with biotechnological purposes.
