The gene encoding a putative mature antitumor-analgesic peptide (AGAP) from the venom of the Chinese scorpion Buthus martensii Karsch was obtained by polymerase chain reaction (PCR) according to its cDNA sequence and expressed in Escherichia coli. While most of the recombinant AGAP was expressed in the form of insoluble inclusion body. The recombinant AGAP was purified to homogeneity by metal chelating affinity chromatography. Pharmaceutical tests showed that the recombinant AGAP has both analgesic and antitumor activities on mice.

Comparative genetic mapping and a consensus interspecific genetic map reveal strong synteny and collinearity within the genus.

Introduction: Useful germplasm for citrus breeding includes all sexually compatible species of the former genera , and , now merged in the single genus. An improved knowledge on the synteny/collinearity between the genome of these different species, and on their recombination landscapes, is essential to optimize interspecific breeding schemes.
Method: We have performed a large comparative genetic mapping study including several main clades of the genus.

Article Synopsis
- Genetic diversity among species is influenced by life history traits, particularly mating systems, with self-pollinating species showing lower genetic diversity compared to outcrossing ones.
- Research indicates that selfing amplifies linked selection, affecting genetic diversity across the genome, though it also may be influenced by population bottlenecks and turnover rates.
- In a study of various grass species with differing mating systems, findings reveal that selfing significantly impacts genetic diversity and selection efficacy, suggesting adaptive traits are primarily found in regions with high recombination in outcrossing species.
duplicons associate with structural diversity at Chromosome 10q11.22.

The 10q11.22 chromosomal region is a duplication-rich interval of the human genome and one of the last to be fully assembled. It carries copy number-variable genes associated with intellectual disability, bipolar disorder, and obesity.

Social insects, particularly honey bees, have exceptionally high genomic frequencies of genetic recombination. This phenomenon and underlying mechanisms are poorly understood. To characterise the patterns of crossovers and gene conversion in the honey bee genome, a recombination map of 187 honey bee brothers was generated by whole-genome resequencing.

Over half of the world's arable land is acidic, which constrains cereal production. In South America, different rice-growing regions (Cerrado in Brazil and Llanos in Colombia and Venezuela) are particularly affected due to high aluminum toxicity levels. For this reason, efforts have been made to breed for tolerance to aluminum toxicity using synthetic populations.
