在植物适应和物种化过程中抑制再组合

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Seedless Vascular Plants Were the First Tall Plants on Earth

Overview

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.
