Estimation model of potassium content in cotton leaves based on hyperspectral information of multileaf position J. Integr. Agric. (IF 4.8) Pub Date : 2024-03-02 Qiushuang Yao, Huihan Wang, Ze Zhang, Shizhe Qin, Lulu Ma, Xiangyu Chen, Hongyu Wang, Lu Wang, Xin Lv
Potassium (K) is a highly mobile nutrient element that continuously adjusts its demand strategy among and within cotton leaves through redistribution. This indirectly leads to variations in the leaf potassium content (LKC, %) at different leaf positions. However, owing to the interaction between light and leaf age, leaf sensitivity at different positions to this change varies, including the reflection

Starch plays a crucial role as a storage component, greatly affecting the grain yield and quality of maize ( L.). To meet future demands, it is essential to understand the genetic basis of the natural variation in kernel starch content (SC) for maize breeding. Through a genome-wide association study (GWAS), we identified 84 and 96 loci associated with kernel SC within two years that overlapped with

Optimizing rice yield: evaluating the nitrogen supply characteristics of slow- and controlled-release fertilizers using the leaf nitrogen balance index J. Integr. Agric. (IF 4.8) Pub Date : 2024-03-02 Weike Tao, Qiuli Chen, Weiwei Li, Shen Gao, Jiaqi Li, Yuhui Wang, Sajjad Ahmad, Yanfeng Ding, Ganghua Li
Synchronizing the nitrogen (N) supply of slow- and controlled-release N fertilizers (SCRNFs) with rice N demand is pivotal in substituting multiple urea applications by a single basal application of SCRNFs. Traditional assessment of N supply characteristics focuses mainly on N release patterns, which are only applicable to coated SCRNFs and ignore N transformation mechanisms, thus raising the need

Identification of novel QTLs for resistance to late leaf spot in peanut by SNP array and QTL-seq J. Integr. Agric. (IF 4.8) Pub Date : 2024-03-02 Guanghui Chen, Li Sheng, Lijun Wu, Liang Yin, Shuangling Li, Hongfeng Wang, Xiao Jiang, Heng Wang, Yanmao Shi, Fudong Zhan, Xiaoyuan Chi, Chunjuan Qu, Yan Ren, Mei Yuan
Late leaf spot (LLS) is one of important diseases that causes severe yield losses in peanut. Peanut has various sources of resistance to LLS, and the identification of resistant QTLs and the development of related molecular markers are of great importance for breeding of LLS-resistant peanut. In this study, 173 individual lines of a recombinant inbred line (RIL) population and 48K SNP array for genotyping

ORF138 causes abnormal lipid metabolism in the tapetum leading to Ogu cytoplasmic male sterility in Brassica napus J. Integr. Agric. (IF 4.8) Pub Date : 2024-03-02 Xiaoyu Ge, Junlin Chen, Ouqi Li, Min Zou, Baolong Tao, Lun Zhao, Jing Wen, Bin Yi, Jinxing Tu, Jinxiong Shen
Plant cytoplasmic male sterility is caused by mutations and rearrangements of mitochondrial genes. It serves as a significant way to utilize hybrid vigor to enhance crop yield. Ogu CMS is a natural cytoplasmic male sterility type discovered in radishes, being successfully transferred to rapeseed and cruciferous vegetables. However, current studies lack depth in exploring the molecular mechanisms of

Development of an Agrobacterium tumefaciens-mediate transformation system for somatic embryos and transcriptome analysis of LcMYB1’s inhibitory effect on somatic embryogenesis in Litchi chinensis. J. Integr. Agric. (IF 4.8) Pub Date : 2024-03-02 Yaqi Qin, Bo Zhang, Xueliang Luo, Shiqian Wang, Jiaxin Fu, Zhike Zhang, Yonghua Qin, Jietang Zhao, Guibing Hu
Litchi holds paramount economic significance as a global fruit crop. However, the advancement of litchi functional genomics encounters substantial obstacles due to its recalcitrance to stable transformation. Here, we present an efficacious -mediated transformation system in somatic embryo of ‘Heiye’ litchi. This system was developed through meticulous optimization of variables encompassing explant

Bioinformatics analysis of type II toxin-antitoxin systems and regulatory functional assessment of HigBA and SS-ATA in Streptococcus suis J. Integr. Agric. (IF 4.8) Pub Date : 2024-03-02 Qibing Gu, Xiayu Zhu, Qiankun Bai, Chengyuan Ji, Yue Zhang, Jiale Ma, Huochun Yao, Zihao Pan
Toxin-antitoxin (TA) systems, which are prevalent in bacteria and archaea, play diverse roles in bacterial physiology and have been proposed to be significant in stress adaptation. Despite the extensive characterization of numerous TA systems in various bacteria, the investigation of these systems within () is still limited. Here, we systematically analyzed the type II TA systems of 95 genomes available

Intramuscular Fat Deposition in pig: A Key Target for Improving Pork Quality1 J. Integr. Agric. (IF 4.8) Pub Date : 2024-03-02 Qi Han, Xingguo Huang, Jun He, Yiming Zeng, Jie Yin, Yulong Yin
Intramuscular fat (IMF) is an important economic trait for pork quality, affecting meat flavour, juiciness, and tenderness. Hence, the improvement of IMF content is one of the hotspots of animal science to provide better meat product. Here, we found that most IMF-related genes are enriched in lipid metabolism processes, including fatty acid transport and uptake, fatty acid beta oxidation, lipid synthesis
