Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Underground plant-associated microbiomes – soil, root, and rhizosphere – are critical to plant health and growth. Plant growth-promoting bacteria (PGPB) are being identified and tested to increase crop productivity and improve sustainability. However, the bacteria introduced as PGPB usually do not persist in soils, despite improving plant growth. If PGPB are promoting plant growth without establishing in the environment or plant microbiome, how are they continuing to influence plant growth? To answer this question, a recent study examined the influence of PGPB treatment on pokeweed. The PGPB inocula in this study had little influence on the rhizosphere microbiome assembly and did not colonize the plant roots. Instead, the PGPB induced DNA methylation in the roots. Methylation is an epigenetic mechanism that influences which genes are expressed and is sometimes passed on to offspring..."
