The Bax inhibitor GmBI-1α interacts with a Nod factor receptor and plays a dual role in the legume-rhizobia symbiosis.

The gene networks surrounding Nod factor receptors that govern the symbiotic process between legumes and rhizobia remain largely unexplored. Here, we identify 13 novel GmNFR1α-associated proteins by yeast two-hybrid screening, and describe a potential interacting protein, GmBI-1α. GmBI-1α had the highest positive correlation with GmNFR1α in a co-expression network analysis, and its expression at the mRNA level in roots was enhanced by rhizobial infection.

Pd-Sn Alloy Catalysts for Direct Synthesis of Hydrogen Peroxide from H and O in a Microchannel Reactor.

Direct synthesis of hydrogen peroxide (DSHP) from H and O offers a promising alternative to the present commercial anthraquinone method, but it still faces the challenges of low HO productivity, low stability of catalysts, and high risk of explosion. Herein, by loading in a microchannel reactor, the as-synthesized Pd-Sn alloy materials exhibit high catalytic activity for HO production, presenting a HO productivity of 3124 g kg h. The doped Sn atoms on the surface of Pd not only facilitate the release of HO but also effectively slow down the deactivation of catalysts.

Identification of the Important Genes of 113-2 Involved in Soybean Nodule Development and Senescence.

Legume nodule development and senescence directly affect nitrogen fixation efficiency and involve a programmed series of molecular events. These molecular events are carried out synchronously by legumes and rhizobia. The characteristics and molecular mechanisms of nitrogen fixation at soybean important developmental stages play critical roles in soybean cultivation and fertilizer application.

Characteristics and Research Progress of Legume Nodule Senescence.

Delaying the nodule senescence of legume crops can prolong the time of nitrogen fixation and attenuate the lack of fertilizer in the later stage of legume crop cultivation, resulting in improved crop yield and reduced usage of nitrogen fertilizer. However, effective measures to delay the nodule senescence of legume crops in agriculture are relatively lacking. In the present review, we summarized the structural and physiological characteristics of nodule senescence, as well as the corresponding detection methods, providing technical support for the identification of nodule senescence phenotype.
