Sugarcane is a globally significant crop for sugar and energy production, yet its breeding potential is limited by its complex genetic background and restricted genetic diversity. Molecular breeding presents a promising approach to boost sugarcane productivity. Gibberellins (GA) plays a critical role in plant growth and development, with GA20-oxidase being the most crucial enzyme in GA biosynthesis.

Plants convert solar energy and carbon dioxide into organic compounds through photosynthesis. Sucrose is the primary carbonate produced during photosynthesis. Sucrose phosphate synthase (SPS) is the key enzyme controlling sucrose biosynthesis in plants.

Sugarcane, a C plant, provides most of the world's sugar, and a substantial amount of renewable bioenergy, due to its unique sugar-accumulating and feedstock properties. Brazil, India, China, and Thailand are the four largest sugarcane producers worldwide, and the crop has the potential to be grown in arid and semi-arid regions if its stress tolerance can be improved. Modern sugarcane cultivars which exhibit a greater extent of polyploidy and agronomically important traits, such as high sugar concentration, biomass production, and stress tolerance, are regulated by complex mechanisms.

Article Synopsis
  • Sugarcane is the primary sugar crop globally, responsible for over 80% of total sugar production, but faces significant threats from pests that can lead to major yield losses.
  • This study investigates how sugarcane responds at the genetic and metabolic levels to attacks from a key pest, examining changes in gene expression and metabolite production following 72 hours of insect feeding.
  • The findings highlight specific defense genes related to amino acid and secondary metabolite production, as well as plant hormone signaling, providing insights that could help in developing more pest-resistant sugarcane varieties through molecular breeding.

Background: Sugarcane is the most important sugar crop, contributing > 80% of global sugar production. High sucrose content is a key target of sugarcane breeding, yet sucrose improvement in sugarcane remains extremely slow for decades. Molecular breeding has the potential to break through the genetic bottleneck of sucrose improvement.

Bojer is an important sugarcane pest globally. Along with genetic modification strategies, the sterile insect technique (SIT) has gained more attention as an environment-friendly method for pest control. The identification of key genes associated with sex determination and differentiation will provide important basic information for this control strategy.

Background: Sugarcane is a major crop producing about 80% of sugar globally. Increasing sugar content is a top priority for sugarcane breeding programs worldwide, however, the progress is extremely slow. Owing to its commercial significance, the physiology of sucrose accumulation has been studied extensively but it did not lead to any significant practical outcomes.
