Burkholderia sensu lato is a large and complex group, containing pathogenic, phytopathogenic, symbiotic and non-symbiotic strains from a very wide range of environmental (soil, water, plants, fungi) and clinical (animal, human) habitats. Its taxonomy has been evaluated several times through the analysis of 16S rRNA sequences, concantenated 4?7 housekeeping gene sequences, and lately by genome sequences. Currently, the division of this group into Burkholderia, Caballeronia, Paraburkholderia, and Robbsia is strongly supported by genome analysis. These new genera broadly correspond to the various habitats/lifestyles of Burkholderia s.l., e.g., all the plant beneficial and environmental (PBE) strains are included in Paraburkholderia (which also includes all the N2-fixing legume symbionts) and Caballeronia, while most of the human and animal pathogens are retained in Burkholderia sensu stricto. However, none of these genera can accommodate two important groups of species. One of these includes the closely related Paraburkholderia rhizoxinica and Paraburkholderia endofungorum, which are both symbionts of the fungal phytopathogen Rhizopus microsporus. The second group comprises the Mimosa-nodulating bacterium Paraburkholderia symbiotica, the phytopathogen Paraburkholderia caryophylli, and the soil bacteria Burkholderia dabaoshanensis and Paraburkholderia soli. In order to clarify their positions within Burkholderia sensu lato, a phylogenomic approach based on a maximum likelihood analysis of conserved genes from more than 100 Burkholderia sensu lato species was carried out. Additionally, the average nucleotide identity (ANI) and amino acid identity (AAI) were calculated. The data strongly supported the existence of two distinct and unique clades, which in fact sustain the description of two novel genera Mycetohabitans gen. nov. and Trinickia gen. nov. The newly proposed combinations are Mycetohabitans endofungorum comb. nov., Mycetohabitansrhizoxinica comb. nov., Trinickia caryophylli comb. nov., Trinickiadabaoshanensis comb. nov., Trinickia soli comb. nov., and Trinickiasymbiotica comb. nov. Given that the division between the genera that comprise Burkholderia s.l. in terms of their lifestyles is often complex, differential characteristics of the genomes of these new combinations were investigated. In addition, two important lifestyle-determining traits?diazotrophy and/or symbiotic nodulation, and pathogenesis?were analyzed in depth i.e., the phylogenetic positions of nitrogen fixation and nodulation genes in Trinickia via-à-vis other Burkholderiaceae were determined, and the possibility of pathogenesis in Mycetohabitans and Trinickia was tested by performing infection experiments on plants and the nematode Caenorhabditis elegans. It is concluded that (1) T. symbiotica nif and nod genes fit within the wider Mimosa-nodulating Burkholderiaceae but appear in separate clades and that T. caryophyllinif genes are basal to the free-living Burkholderia s.l. strains, while with regard to pathogenesis (2) none of the Mycetohabitans and Trinickia strains tested are likely to be pathogenic, except for the known phytopathogen T. caryophylli.

RESUMO: A necessidade de controle adequado de plantas voluntárias de soja (Glycine max) tem se intensificado nos últimos anos em função da incidência de doenças da soja, principalmente a ferrugem asiática ( Phakopsora pachyrhizi). Além disso, a competição imposta por essas plantas pode causar perdas de produtividade em culturas implantadas na entressafra. Dois experimentos foram conduzidos em condições de campo no município de Rio Verde, Goiás, a fim de avaliar o controle de plantas voluntárias de soja infestantes da cultura do girassol (Helianthus annuus), semeado na época de safrinha. O delineamento experimental foi em blocos casualizados, com quatro repetições. Os tratamentos aplicados no experimento 1 foram a testemunha capinada, a testemunha sem capina, sulfentrazone 25 g i.a. ha-1, sulfentrazone 50 g i.a. ha -1, sulfentrazone 100 g i.a. ha-1 e sulfentrazone 150 g i.a. ha-1. No experimento 2, foram aplicados os mesmos tratamentos mencionados e acrescentadas as doses de 200 g i.a. ha-1 e 250 g i.a. ha-1 do mesmo herbicida. O sulfentrazone não proporciona morte completa das plantas voluntárias de soja. No entanto, há uma interrupção temporária do crescimento da soja permitindo o arranque inicial da cultura de girassol. As doses de sulfentrazone que variaram de 114,2 a 158,8 g i.a. ha-1 proporcionaram os maiores rendimentos de girassol, evitando a competição das plantas voluntárias de soja com essa cultura. ABSTRACT: The control of volunteer soybean plants (Glycine max ) has intensified in recent years in function of the increasing incidence of soybean diseases mainly the Asian soybean rust (Phakopsora pachyrhizi). Moreover, the competition of volunteer soybean plants can cause yield losses in successive crops. Two experiments were conducted under field conditions in Rio Verde, Goiás State, Brazil, in order to evaluate the control of volunteer soybean plants in sunflower (Helianthus annuus). The experimental design was a randomized complete block, with four replications. Treatments applied on experiment 1 were: hoed check; unhoed check, sulfentrazone 25 g ai ha-1, sulfentrazone 50 g ai ha-1, sulfentrazone 100 g ai ha-1, sulfentrazone 150 g ai ha-1. The treatments applied on experiment 2 were the same doses described on experiment 1 plus sulfentrazone 200 g ai ha-1 and 250 g ai ha-1. The sulfentrazone is unable to completely kill the volunteer soybean plants. However, there is a temporary stoppage of soybean growth enabling the initial startup of the sunflower plants. Doses ranging from 114.2 to 158.8 g ai ha-1 provided the highest sunflower yield, avoiding the competition of the volunteer soybean plants.
