Plant growth stimulation by microorganisms that interact in a mutually beneficial manner remains poorly understood. Understanding the nature of plant-bacteria interactions may open new routes for plant productivity enhancement, especially cereal crops consumed by humans. Proteomic and metabolomic analyses are particularly useful for elucidating these mechanisms. A complete depiction of these mechanisms will prompt researchers to develop more efficient plant-bacteria associations. The success of microorganisms as biofertilizers may replace the current massive use of chemical fertilizers, mitigating many environmental and economic issues. In this review, we discuss the recent advances and current state of the art in proteomics and metabolomics studies involving grass-bacteria associations. We also discuss essential subjects involved in the bacterial plant-growth promotion, such, nitrogen fixation, plant stress, defense responses, and siderophore production.
Zootechnical performance and interaction between Penaeus schmitti Burkenroad, 1936 and Penaeus vannamei Boone, 1931 reared under laboratory conditions FERNANDEZ DE ALAIZA GARCIA MADRIGAL, RAFAEL; DA SILVA, UBIRATÃ DE ASSIS TEIXEIRA; Eduardo Luis Cupertino Ballester Latin American Journal of Aquatic Research, v. 48, n. 3, p. 342-356, 2020 DOI Palavra-chave: Aquicultura; Carcinicultura Áreas do conhecimento: CIENCIAS_AGRARIAS; Aqüicultura; Ciências Biológicas; Biologia Geral; Aquacultura; Carcinicultura resumo ... (en) To compare the zootechnical performance of the Brazilian native shrimp Penaeus schmitti and the exotic shrimp Penaeus vannamei , juveniles were grown under controlled conditions. Both species were simultaneously cultivated (monoculture) in separate 70 L plastic tanks at two different densities: 30 and 50 ind m -2 . Also, in the other two treatments, both species were cultivated together (mixed), with and without feeding, at 30 ind m -2 . During the experiment, P. vannamei generally showed a greater interest in food and voracity than P. schmitti . At harvest, for both stocking densities of monoculture treatments, the mean growth rate observed for P. vannamei was 1.0 g week -1 , while P. schmitti achieved only 0.1 g week -1 . The mean final weight was 10.4 ± 2.0 g; 10.7 ± 2.1 g for P. vannamei and 2.8 ± 0.3 g; 3.2 ± 0.3 g for P. schmitti , for respective densities of 50 and 30 ind m -2 . In the mixed treatment with feeding, while P. vannamei reached 11.9 ± 1.4 g, P. schmitti reached only 2.6 ± 0.4 g in the same tank. The observed differences were 3.7 and 3.4 higher in favor of P. vannamei in the monoculture treatment, and up 4.5 times higher in the mixed treatment. Under strict fasting conditions, both species practiced predation/cannibalism among themselves. The results reflected the zootechnical advantages of P. vannamei , but also corroborated the negative effect that high densities and lack of natural food can exert over native species. The potential for P. schmitti cultivation and the possible impact of the escape of P. vannamei into the natural environment is discussed.
Rearrangements in some species groups of Amblycerus Thunberg, 1815 (Coleoptera: Chrysomelidae: Bruchinae) including keys, description of a new species, new host plant and distributional records Aluska Tavares dos Santos; Cibele Stramare Ribeiro-Costa ZOOTAXA (ONLINE), v. 4701, p. 101-148, 2019 DOI Palavra-chave: Taxonomia; morfologia; Espécie nova Áreas do conhecimento: Ciências Biológicas; Zoologia; Taxonomia dos Grupos Recentes; Ciências Biológicas; Zoologia; Morfologia dos Grupos Recentes resumo ... (en) Encompassing 39 species groups, Amblycerus Thunberg, 1815 is the second most diverse genus of seed-beetles in the Americas. Considering that the delimitation of some of the included species-groups is incongruent in the literature, this work tackled one particularly problematic group, the dispar group, which includes species that, depending on the classification scheme, have been classified in two other groups, namely the spondiae and alternatus groups. We recognize six valid species in the dispar group, viz. A. dispar (Sharp, 1885), A. crassipunctatus Ribeiro-Costa, 1999c A. insuturatus (Pic, 1902), A. schwarzi Kingsolver, 1970, A. taeniopygus Ribeiro-Costa, 1999 c, and Amblycerus goianiensis Santos & Ribeiro-Costa, sp. n. , and four in the spondiae group, viz. A. spondiae Kingsolver, 1980, A. cuernavacensis Romero, Johnson & Kingsolver, 1996, A. vitis (Schaeffer, 1907) and A. alternatus (Pic, 1954). Three species are excluded from their original groups, namely A. eustrophoides (Schaeffer, 1904), A. serieguttatus (Chevrolat, 1877), from the alternatus group, and A. simulator (Jacquelin DuVal, 1857), from the dispar group, all considered here as incertae sedis. The remaining species of the alternatus group, A. schwarzi and A. alternatus , are transferred to other previously mentioned groups, thus dissolving this group. We provide diagnoses for the 13 species studied, redescribe three species, and describe one new species. Color illustrations of the dorsum and pygidium, drawings of the male genitalia and geographic distribution maps are included. Identification keys are also added for the dispar and spondiae groups. We record new host plants for four Amblycerus species and new localities for five species. The plant taxa Sarcomphalus mistol (Griseb.) Hauenschild, Terminalia corrugata (Ducke) Gere & Boatwr., T . tetraphylla (Aubl.) Gere & Boatwr. and Rhus virens Lindh. ex A. Gray var. choriophylla (Wooton & Standl.) L. D. Benson are first registered here as hosts of Amblycerus . Four new records for Amblycerus , namely Capparis , Neopringlea, Rhus and Sarcomphalus , and two new records at the family level, Capparaceae A. Juss. and Salicaceae Mirb., the latter also being a new record for Bruchinae.

A new species of Huberia (Melastomataceae) from Espírito Santo, Brazil BOCHORNY, THUANE; Renato Goldenberg BRITTONIA, v. 71, p. 408-413, 2019 DOI resumo ... We describe and illustrate Huberia misteriosa, a new species endemic to the state of Espírito Santo, Brazil. The new species can be recognized by the young branches and abaxial surface of the leaves covered with dendritic trichomes 0.5–1 mm long, hypanthium covered with stalked glands, sepals with the internal laminae broadly trapezoidal, with the apex truncate and shortly apiculate, and by the petals with an apiculate apex. We also provide taxonomic comments, comparisons with closely related species, information about distribution and photos of living and dry specimens.
