Summary
This study maps 194 rice genes for traits like disease resistance and drought tolerance, identifying linked molecular markers. Fourteen genes are cloned, aiding in understanding gene distribution on chromosomes for crop improvement.
Area of Science:
- Genetics and Genomics
- Plant Breeding
- Molecular Biology
Context:
- Gene mapping is crucial for isolating genes and developing molecular markers for marker-assisted selection in rice.
- Understanding the genetic basis of important agronomic traits is essential for crop improvement.
Purpose:
- To summarize recent gene mapping studies in rice, covering 194 genes.
- To identify and summarize molecular markers linked to these rice genes.
- To analyze the distribution patterns of these mapped genes on rice chromosomes.
Summary:
- This paper reviews 194 mapped rice genes involved in critical traits such as disease resistance, cold and drought tolerance, and sterility/fertility restoration.
- Linked molecular markers for these genes are cataloged, with 14 genes identified as cloned and sequenced.
- Analysis of gene distribution rules across rice chromosomes is presented based on the summarized data.
Impact:
- Provides a comprehensive overview of rice gene mapping resources.

02:24Ribosome Profiling
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

01:17Karyotyping
Describing the number and physical features of chromosomes can reveal abnormalities that underlie genetic diseases. This description is facilitated by special staining techniques that produce a particular banding pattern on each chromosome. State-of-the-art techniques make this approach even more powerful, enabling the detection of individual genes that cause disease.A Simple Chromosome Staining Technique Provides Valuable Scientific InsightSome genetic diseases can be detected by looking at...
02:05Gene Evolution - Fast or Slow?
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

02:38Heterochromatin
The extent of chromatin compaction can be studied by staining chromatin using specific DNA binding dyes. Under the microscope, the dense-compacted regions that take up more dye are called heterochromatin. Heterochromatin is further classified into two forms – constitutive heterochromatin and facultative heterochromatin.
Constitutive heterochromatin: It is a highly compact region of chromatin that is mostly concentrated in the centromere and telomere. Unlike euchromatin, the amino acid at 9th...

02:35Chromatin Position Affects Gene Expression
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

02:32Position-effect Variegation
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
