Background: Plant hormones influence phenology, development, and function of above and belowground plant structures. In seedlings, auxin influences the initiation and development of lateral roots and root systems. How auxin-related genes influence root initiation at early life stages has been investigated from numerous perspectives.

Phenology, or seasonal variation in life cycle events, is poorly described for many macroalgal species. We describe the phenology of a non-native population of Gracilaria vermiculophylla whose thalli are free-living or anchored by decorating polychaetes to tube caps. At a site in South Carolina, USA, we sampled 100 thalli approximately every month from January 2014 to January 2015.

In-person undergraduate research experiences (UREs) promote students' integration into careers in life science research. In 2020, the COVID-19 pandemic prompted institutions hosting summer URE programs to offer them remotely, raising questions about whether undergraduates who participate in remote research can experience scientific integration and whether they might perceive doing research less favorably (i.e.

The COVID-19 pandemic shut down undergraduate research programs across the United States. A group of 23 colleges, universities, and research institutes hosted remote undergraduate research programs in the life sciences during Summer 2020. Given the unprecedented offering of remote programs, we carried out a study to describe and evaluate them.

Article Synopsis
  • The study investigates how signatures of selection in DNA sequences relate to the actual effects of genes on reproductive fitness in plants, specifically using the model organism Arabidopsis thaliana.
  • Researchers calculated various statistics to infer selection and compared them to experimental data on gene effects on fitness, finding that essential genes were more likely to show negative selection.
  • The findings reveal no significant difference in the fitness effects of genes predicted to be positively selected versus those evolving neutrally, emphasizing the need for more experimental fitness data in genetic studies across different species.
