Chronic obstructive pulmonary disease (COPD), a condition primarily linked to oxidative stress, poses significant health burdens worldwide. Recent evidence has shed light on the association between dysbiosis of gut microbiota and COPD, their metabolites have emerged as potential modulators progression through intricate gut-lung axis.

The NAC transcription factor (TF) is one of the most significant TFs in plants and widely involved plant growth, development, responses to biotic abiotic stresses. To date, there are no systematic studies on family peanuts. Herein, 132 AhNACs were identified from genome cultivated peanut, they classified into eight subgroups (I–VIII) based phylogenetic relationships with Arabidopsis proteins their conserved motifs. These genes unevenly scattered all 20 chromosomes, among which 116 pairs...

Peanut (Arachis hypogaea L.) is one of the major oil crops and fifth largest source plant oils in world. Numerous genes participate regulating biosynthesis accumulation storage lipids seeds or other reservoir organs, among which several transcription factors, such as LEAFY COTYLEDON1 (AtLEC1), LEC2, WRINKLED1 (WRI1), involved embryo development also control lipid seeds. In this study, AtLEC1 gene was transferred into peanut genome expressed a seed-specific manner driven by NapinA full-length...

In this article, we present a general optimization framework that leverages structured sparsity to achieve superior recovery results. The traditional method for solving the sparse objectives based on l2,0-norm is use l2,1-norm as convex surrogate. However, such an approximation often yields large performance gap. To tackle issue, first provide allows wide range of surrogate functions (including non-convex surrogates), which exhibits better in harnessing sparsity. Moreover, develop fixed...
