Closely related animal species can look physically different, but you might be surprised to learn that those differences can result not only from DNA sequence changes that alter proteins' structure or function, but also because ...
Bread wheat is one of the most important staple crops for millions of people and is apparently the largest cultivated and traded cereal worldwide. Bread wheat is a hexaploid species with three subgenomes (2n = 6x = 42, AABBDD) ...
Scientists at UC Santa Cruz have discovered a cellular process in the breast that can increase milk production by pregnant women, revealing a potential path to addressing lactation insufficiency syndrome—the inability of ...
Dysregulated R-loops can cause stalled replication forks and telomere instability. However, how R-loops are recognized and regulated, is still not well understood, particularly at telomeres.
Arabica coffee is the most economically important coffee globally and accounts for 60% of coffee products worldwide. But the plants it hails from are vulnerable to a disease that, in the 1800s, devastated Sri Lanka's coffee ...
Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, ...
From microbes in the human gut to symbiotic algae in coral reefs, research in recent decades has increasingly revealed the pivotal roles that microorganisms (or microbial species) play in shaping the biology of host organisms ...
Most mammals and humans have a double set of chromosomes—and as a rule, plants do, too: One set comes from the father, the other from the mother. Such organisms are called diploids. However, sometimes the number of chromosome ...
The key to growing coffee plants that can better resist climate change in the decades to come may lie in the ancient past.
We depend on our cells being able to divide and multiply, whether it's to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our genetic instructions, must be copied ...
