Endophytic Fungus Drives Nodulation and N2 Fixation Attributable to Specific Root Exudates
mBio, 2019 Endophytic fungi play important roles in the modification of ecosystem productivity; however, the underlying mechanisms are only partly understood. A 2-year field plot experiment verified that the endophytic fungus Phomopsis liquidambaris increased ...

Single-view 2D CNNs with Fully Automatic Non-nodule Categorization for False Positive Reduction in Pulmonary Nodule Detection [PDF]
Computer Methods and Programs in Biomedicine, vol. 165, Oct. 2018,
pp. 215-224, 2020 Background and Objective: In pulmonary nodule detection, the first stage, candidate detection, aims to detect suspicious pulmonary nodules. However, detected candidates include many false positives and thus in the following stage, false positive reduction, such false positives are reliably reduced.

Frontiers in Plant Science, 2018 Transcriptomic approaches revealed thousands of genes differentially or specifically expressed during nodulation, a biological process resulting from the symbiosis between leguminous plant roots and rhizobia, atmospheric nitrogen-fixing symbiotic ...

Deep convolutional neural networks for multi-planar lung nodule detection: improvement in small nodule identification [PDF]
, 2020 Objective: In clinical practice, small lung nodules can be easily overlooked by radiologists. The paper aims to provide an efficient and accurate detection system for small lung nodules while keeping good performance for large nodules. Methods: We propose a multi-planar detection system using convolutional neural networks.

Co-Inoculation of Soybean with Bradyrhizobium and Azospirillum Promotes Early Nodulation
, 2015 Soybean inoculation with elite strains of Bradyrhizobium to improve nodulation, N2 fixation, and grain yield is well established worldwide. However, when grown in soils where N is deficient, soy- bean undergoes an initial phase of N starvation that may ...

Role of LONELY GUY genes in indeterminate nodulation on Medicago truncatula.
New Phytologist, 2014 LONELY GUY (LOG) genes encode cytokinin riboside 5'-monophosphate phosphoribohydrolases and are directly involved in the activation of cytokinins. To assess whether LOG proteins affect the influence of cytokinin on nodulation, we studied two LOG genes of

Faithful learning with sure data for lung nodule diagnosis [PDF]
arXiv, 2022 Recent evolution in deep learning has proven its value for CT-based lung nodule classification. Most current techniques are intrinsically black-box systems, suffering from two generalizability issues in clinical practice. First, benign-malignant discrimination is often assessed by human observers without pathologic diagnoses at the nodule level.

Hijacking of leguminous nodulation signaling by the rhizobial type III secretion system
Proceedings of the National Academy of Sciences of the United States of America, 2013 Significance Root–nodule symbiosis between leguminous plants and rhizobia requires rhizobial Nod factors (NFs) and their leguminous receptors (NFRs). Here we show that symbiosis in the soybean rhizobium Bradyrhizobium elkanii is promoted by the type III ...

Phylogeny and Expression of NADPH Oxidases during Symbiotic Nodule Formation
Agriculture, 2018 The mutualistic interaction between gram-negative soil bacteria and the roots of legumes leads to the establishment of nodules, where atmospheric nitrogen is fixed. Nodulation is a multistep process with numerous essential players.

A Pulmonary Nodule Detection Model Based on Progressive Resolution and Hierarchical Saliency [PDF]
arXiv, 2018 Detection of pulmonary nodules on chest CT is an essential step in the early diagnosis of lung cancer, which is critical for best patient care. Although a number of computer-aided nodule detection methods have been published in the literature, these methods still have two major drawbacks: missing out true nodules during the detection of nodule ...
