Many insects rely on heritable bacterial endosymbionts for essential nutrients that they cannot get through their diet. A new study, published in Nature Communications, indicates that the genomes of ...

Flax is a globally important crop valued for its fiber, industrial uses, and omega-3-rich oil, yet incomplete genomic information has long limited efforts to understand and improve its key traits.

The genome structure — how genes are organized within DNA sequences in an organism — is fundamental to the processes and functions of organisms. A team at the University of Tokyo has developed a ...

Scientists have uncovered a 400-million-year-old genetic secret that gave spiders the ability to produce silk and weave their webs. Spiders didn't begin their journey on Earth in the same way as they ...

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

Evolved macroscopic "snowflake" yeast from the MuLTEE experiment. The large size of the nuclei (yellow) and cells (cyan) are results of whole-genome duplication and aneuploidy. Sometimes, the most ...

Ferns, defined by large genomes, high chromosome counts, and pervasive aneuploidy as well as intraspecific polyploid complexity, diverge significantly from the classical genetic theories and ...

The only remaining autonomous 'jumping gene' can only attach to, and stitch a copy of itself into, DNA when it builds up into large clusters and only as cells divide. Viruses are known to use the ...
