“…Biotrophs, including the phytopathogenic viruses and subsets of bacteria and fungi, gain nutrients from living host cells without killing them. They infect and colonize young plant cells with active metabolism and usually have a long symbiotic phase with the host cells [2]. Necrotrophs, including a large number of bacteria, fungi, and oomycete species, promote the destruction of host cells and derive nutrients from the dead or dying cells [3], and therefore are more adapted to the metabolism of older plants and/or their senescing parts with active catabolic pathways [2].…”

The third group, hemibiotrophs, which include some bacteria and many fungi, initially have a biotrophic stage in the early infection process, but later become necrotrophic.…”

“…Phytopathogenic viruses invade the plant surface and propagate in their cytoplasm as biotrophic pathogens, although some of them can cause very serious disease [2]. BR has been shown to play diverse roles in coping with viral infections, mediating either defense or susceptibility.…”

As sessile organisms, plants are frequently exposed to different stress conditions caused by either biotic or abiotic factors. Understanding the mechanisms that underlie plant interaction with the biotic and abiotic environments is fundamental to both plant biotechnology and sustainable agriculture. Brassinosteroids (BRs) are a group of plant-specific steroidal compounds essential for normal growth and development. Recent research evidence indicates that BRs are also actively involved in plant–environment interactions and play important roles in shaping plant fitness and the growth–defense trade-offs. In this minireview, we focus our attention on recent advances in the understanding of BR functions in modulating plant interactions with different pathogenic microbes, with particular focus on how BR signaling primes the plant innate immunity pathways and achieves a trade-off between growth and immunity.
