WebJul 27, 2024 · In the wild, cryptic variation helps fish adapt to life in caves. In the lab, cryptic variation might help a biomolecule bind a new receptor. “Our work can help develop new directed evolution strategies to find innovative biomolecules for biotechnological and medical applications,” says Zheng.

WebJan 10, 2024 · Developmental plasticity of plant root systems has been the subject of intensive research, but the mechanisms underpinning robustness remain unclear. Here, we show that potassium deficiency inhibits lateral root organogenesis by delaying early stages in the formation of lateral root primordia. WebAug 26, 2008 · The discovery of a prevalent cryptic genetic diversity within species of planktonic foraminifera and other fossil-producing plankton (e.g., ref. 18) implies that evolutionary patterns extracted from fossil microplankton may represent the development of a cohort of cryptic sibling species. did john denver write all his songs https://ponuvid.com
