Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues, or organs under sterile conditions on a nutrient culture medium of known composition. It is widely used to produce clones of a plant in a method known as micropropagation .
Cell isolation is the process of separating individual living cells from a solid block of tissue or cell suspension. While some types of cell naturally exist in a separated form (for example blood cells ), other cell types that are found in solid tissue require specific techniques to separate them into individual cells.
This single cell shows the process of the central dogma of molecular biology, which are all steps researchers are interested to quantify (DNA, RNA, and Protein).. In cell biology, single-cell analysis and subcellular analysis [1] refer to the study of genomics, transcriptomics, proteomics, metabolomics, and cell–cell interactions at the level of an individual cell, as opposed to more ...
Like typical next-generation sequencing experiments, single-cell sequencing protocols generally contain the following steps: isolation of a single cell, nucleic acid extraction and amplification, sequencing library preparation, sequencing, and bioinformatic data analysis. It is more challenging to perform single-cell sequencing than sequencing ...
Reproductive isolation occurs in many organisms, and floral isolation is one form present in plants. [1] Floral isolation occurs prior to pollination, and is divided into two types of isolation: morphological isolation and ethological isolation. [2] Floral isolation was championed by Verne Grant in the 1900s as an important mechanism of ...
A. tumefaciens attaching itself to a carrot cell. In plants the DNA is often inserted using Agrobacterium-mediated recombination, [27] taking advantage of the Agrobacteriums T-DNA sequence that allows natural insertion of genetic material into plant cells. [28] Plant tissue are cut into small pieces and soaked in a fluid containing suspended ...
After successfully transduced cells have been selected for, isolation of single cells is needed to conduct scRNA-seq. Perturb-seq and CROP-seq have been performed using droplet-based technology for single cell isolation, [1] [2] [3] while the closely related CRISP-seq was performed with a microwell-based approach.

The quest for transcriptome data at the level of individual cells has driven advances in RNA-Seq library preparation methods, resulting in dramatic advances in sensitivity. Single-cell transcriptomes are now well described and have even been extended to in situ RNA-Seq where transcriptomes of individual cells are directly interrogated in fixed ...
