Winged Bean cultivars,'fingeWB-21-8 and Siempre WB-12-11, were grown with complete fáctorial soil fertility experiments for P, K, Ca, Mg, and S combinationson a Typic Eutrustox (dark-red latosol) from Central Brazil. Nitrogenase (C2H2 reduction), growth, and associated nodule enzyme parameters and composition were determined at anthesis. Highly significant increases in nitrogenase activity levels resulted with applied P and K for both cultivars with significant increases for Ca additions. Growth,,nodulatíon and cytosol enzyme activity levels of GOT, GDH, GS and GOGAT all increased significantly with applied P, with the exception of GDH to applied K. a KG was increased to highly significant levels with K treatment. Cytosol composition was increased sígnificantly for each plant nutrient element contained in the treatment combinations. Highly signíficant inverse retroversion existed for K and Na. Na was negatively correlated with every parameter determined in these studies for both cultivars. Practical application of these data include the requirement for adequate available soil K and P for increased symbiotic N fixation and NH4'incorporation into amino acid components of the host legume symbionÊ |

Sugarcane is an economically important crop that is used for the production of fuel ethanol. Diazotrophic bacteria have been isolated from sugarcane tissues, without causing visible plant anatomical changes or disease symptoms. These bacteria can be beneficial to the plant by promoting root growth and an increase in plant yield. Different rates of Biological Nitrogen Fixation (BNF) were observed in different genotypes. The aim of this work was to conduct a comprehensive molecular and physiological analysis of two model genotypes for contrasting BNF efficiency in order to unravel plant genes that are differentially regulated during a natural association with diazotrophic bacteria. A next-generation sequencing of RNA samples from the genotypes SP70-1143 (high-BNF) and Chunee (low-BNF) was performed. A differential transcriptome analysis showed that several pathways were differentially regulated among the two BNF-contrasting genotypes, including nitrogen metabolism, hormone regulation and bacteria recognition. Physiological analyses, such as nitrogenase and GS activity quantification, bacterial colonization, auxin response and root architecture evaluation, supported the transcriptome expression analyses. The differences observed between the genotypes may explain, at least in part, the differences in BNF contributions. Some of the identified genes might be involved in key regulatory processes for a beneficial association and could be further used as tools for obtaining more efficient BNF genotypes.
