AI Article Synopsis

  • Sugarcane is a vital global crop that suffers yield losses from pathogens and herbivores.
  • Plants, including sugarcane, produce specific proteins (like glucanases and defensins) in response to infections, aiding in their defense against these threats.
  • The review discusses the roles of these defense proteins, their mechanisms, target pathogens, and potential biotechnological applications in improving sugarcane resilience.

Article Abstract

Sugarcane is one of the most important agricultural crops in the world. However, pathogen infection and herbivore attack cause constant losses in yield. Plants respond to pathogen infection by inducing the expression of several protein types, such as glucanases, chitinases, thaumatins, peptidase inhibitors, defensins, catalases and glycoproteins. Proteins induced by pathogenesis are directly or indirectly involved in plant defense, leading to pathogen death or inducing other plant defense responses. Several of these proteins are induced in sugarcane by different pathogens or insects and have antifungal or insecticidal activity. In this review, defense-related proteins in sugarcane are described, with their putative mechanisms of action, pathogen targets and biotechnological perspectives.

Background: Mutualistic mycorrhiza fungi that live in symbiosis with plants facilitates nutrient and water acquisition, improving tree growth and performance. In this study, we evaluated the potential of mutualistic fungal inoculation to improve the growth and disease resistance of Scots pine (Pinus sylvestris L.) against the forest pathogen Heterobasidion annosum.

Valsa canker, caused by fungal pathogens in Valsa species, is a fungal disease of apple and pear growing in China and even in Asia. Malectin-like kinases play crucial roles in plant recognition of the pathogen-induced signals and subsequent activation of partially host immune responses. However, the role of MEDOS1 (MDS1), a Malectin-like kinase, in plant immunity has not yet been extensively explored.

Background: Rice is the main food crop for much of the population in China. Therefore, selecting and breeding new disease resistance and drought tolerance in rice is essential to ensure national food security. The utilization of heterosis has significantly enhanced rice productivity, yet many of the molecular mechanisms underlying this phenomenon remain largely unexplored.
