Abstract

<p xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="first" id="d105442e91">The plant hormone salicylic acid plays an important role in balancing plant immunity and growth. In this issue of Cell Host & Microbe, Liu et al. (2022) discovered that a long non-coding RNA, lncSABC1, promotes growth in uninfected plants and unleashes defenses when pathogens attack by transcriptionally regulating salicylic acid biosynthesis. </p>

The plant immune system.

Jonathan Jones, Jeffery Dangl (2006)

Many plant-associated microbes are pathogens that impair plant growth and reproduction. Plants respond to infection using a two-branched innate immune system. The first branch recognizes and responds to molecules common to many classes of microbes, including non-pathogens. The second responds to pathogen virulence factors, either directly or through their effects on host targets. These plant immune systems, and the pathogen molecules to which they respond, provide extraordinary insights into molecular recognition, cell biology and evolution across biological kingdoms. A detailed understanding of plant immune function will underpin crop improvement for food, fibre and biofuels production.

Growth-defense tradeoffs in plants: a balancing act to optimize fitness.

Bethany Huot, Jian Yao, Beronda Montgomery … (2014)

Growth-defense tradeoffs are thought to occur in plants due to resource restrictions, which demand prioritization towards either growth or defense, depending on external and internal factors. These tradeoffs have profound implications in agriculture and natural ecosystems, as both processes are vital for plant survival, reproduction, and, ultimately, plant fitness. While many of the molecular mechanisms underlying growth and defense tradeoffs remain to be elucidated, hormone crosstalk has emerged as a major player in regulating tradeoffs needed to achieve a balance. In this review, we cover recent advances in understanding growth-defense tradeoffs in plants as well as what is known regarding the underlying molecular mechanisms. Specifically, we address evidence supporting the growth-defense tradeoff concept, as well as known interactions between defense signaling and growth signaling. Understanding the molecular basis of these tradeoffs in plants should provide a foundation for the development of breeding strategies that optimize the growth-defense balance to maximize crop yield to meet rising global food and biofuel demands. © The Author 2014.
