Sugarcane proteomics: An update on current status, challenges, and future prospects

Abstract

Sugarcane is one of the most important commercial crops cultivated worldwide for the production of crystal sugar, ethanol, and other related by-products. Unlike other comparable monocots like sorghum, maize, and rice, sugarcane genome by virtue of its polyploidy nature remains yet to be fully deciphered. Proteomics-an established complementary tool to genomics is at its infancy in sugarcane as compared to the other monocots. However, with the surge in genomics research accomplished by next-generation sequencing platforms, sugarcane proteomics has gained momentum. This review summarizes the available literature from 1970 to 2014, which ensures a comprehensive coverage on sugarcane proteomics-a topic first of its kind to be reviewed. We herewith compiled substantial contributions in different areas of sugarcane proteomics, which include abiotic and biotic stresses, cell wall, organelle, and structural proteomics. The past decade has witnessed a paradigm shift in the pace with which sugarcane proteomics is progressing, as evident by the number of research publications. In addition to extensively reviewing the progress made thus far, we intend to highlight the scope in sugarcane proteomics, with an aspiration to instigate focused research on sugarcane to harness its full potential for the human welfare.

Comparative Transcriptome Profiling of Resistant and Susceptible Sugarcane Cultivars in Response to Infection by Xanthomonas albilineans

“…hybrids) is a major source of sugar and biofuel production worldwide, and it is one of the most valuable cash crops [1]. In addition to sugar and biofuel production, sugarcane is also used to produce fodder for livestock and cellulosic ethanol, a second-generation biofuel using by-products from cane sugar processing such as straw and cane fibers [2]. The current commercial cultivars are interspecific hybrids derived from crosses between a few parents belonging to S. officinarum (2n = 80, the noble sugarcane), S. barberi (2n = 111-120, the Indian sugarcanes), S. sinense (2n = 81-124, the Chinese sugarcanes), and the two wild species S. spontaneum (x = 8, 2n = 36-128) and S. robustum (x = 10, 2n = 60-80) [1,3].…”

Advances in proteomic technologies and their scope of application in understanding plant–pathogen interactions

“…This has resulted in inaccuracy in identification of proteins during post-data acquisition (in silico) analysis (Barnabas et al 2015). Similarly, lack of standard protocol for protein extraction from hardy tissues, membranes/cell wall and apoplastic spaces from major crops remains a serious hurdle for realizing the full potential of proteomics in such systems.…”

Biotechnological Interventions for the Improvement of Sugarcane Crop and Sugar Production

“…It has also helped to understand the mode of actions, resistance mechanisms and bio-degradation of pesticides. However, in sugarcane, proteome study is a little bit complicated as no standard protein extraction protocol is available [49]. As compared to other monocots, sugarcane proteomics have not gained momentum yet.…”
