Sugarcane somatic cell hybridization can break through the barrier of genetic incompatibility between distantly related species in traditional breeding. However, molecular mechanisms sugarcane protoplast regeneration and conditions for preparation remain largely unknown. In this study, young (ROC22) leaves were enzymatically digested, viability protoplasts reached more than 90% after enzymatic digestion (Enzymatic combination: 2% cellulase + 0.5% pectinase 0.1% dissociative enzyme 0.3%...

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a single stranded RNA virus which has resulted in the Disease 2019 (COVID-19) pandemic and infected millions of people all over world. SARS-CoV-2 been mutating rapidly resulting emergence multiple variants to escape host immune system mainly by mutations its receptor binding domain (RBD) spike protein. This rapid evolution posed great challenge regarding efficacy effectiveness current vaccines. The RBD full-length main target...

Somatic cell fusion is a process that transfers cytoplasmic and nuclear genes to create new germplasm resources. But our limited understanding of the physiological molecular mechanisms shape protoplast responses fusion.We employed flow cytometry, cytology, proteomics, gene expression analysis examine sugarcane (Saccharum spp.) fusion.Flow cytometry revealed rate protoplasts was 1.95%, FSC value SSC heterozygous cells 1.17-1.47 times higher than protoplasts. The viability decreased MDA...

The influence of low oxygen on the biosynthesis aroma-related esters and alcohols in strawberries has been well revealed. However, how low-oxygen conditions affect other volatile compounds, such as terpenes furans, is still to be elucidated.The effects 2 kPa O2 aroma 'Benihoppe' were comprehensively investigated this study. results showed that, like esters, accumulations key terpene furans also inhibited by during storage subsequent shelf life, which was associated with down-regulation...

The impact of low-oxygen (2 kPa) controlled atmosphere storage on the recovery aroma biosynthesis in ‘Golden Delicious’ (GD) apple tissues during their subsequent shelf life was investigated. results showed that highest ester content found skin tissue, followed by Flesh 2 and 1. kPa O2 GD apples resulted a decrease emission volatile esters alcohols, but an increase aldehyde emission. Notably, compared with flesh tissue O2-stored had relatively high capacity low alcohol synthesis for its...

The protoplast experimental system eis an effective tool for functional genomics and cell fusion breeding. However, the physiological molecular mechanisms of response to enzymolysis are not clear, which has become a major obstacle regeneration. Here, we used physiological, cytological, proteomics gene expression analysis compare young leaves sugarcane enzymolized protoplasts. After enzymatic digestion, obtained protoplasts with viability > 90%. Meanwhile, content malondialdehyde,...

Accurate human leucocyte antigen (HLA) and platelet (HPA) typing is essential for establishing a blood donor bank to deal with refractoriness in patients undergoing multiple transfusions. Current methods, such as Sanger next-generation sequencing, encounter difficulties haplotyping. Herein, the aim of this study was establish method HLA HPA based on long read sequencing.
