Root proteome alterations of sugarcane cultivar RB966928 promoted by regrowth cycle in commercial production

ABSTRACT: Decrease in agricultural productivity in successive cuttings of sugarcane plants has been related to several extrinsic and intrinsic factors, even though no studies have been recently conducted to assess the physiological potential of sett roots in successive cuts in sugarcane culture. Proteomic studies on sugarcane sett roots at different cut stages are unknown. The UPLC-ESI-TOF-MS system and bioinformatics tools were used to identify proteins of sett roots in the first and fifth cuts of sugarcane cultivar RB966928 in the sprouting stage. The differences in proteome of sett roots from sugarcane cv. RB966928 in the first and fifth cut detected in current study support the hypothesis that the proteome of sett roots may change after successive cuts in sugarcane culture. A reduction in the number of proteins has been observed in the roots of the fifth cut, while 34% of proteins, identified exclusively in the first cut, were absent in the fifth one. Proteome analysis of sett roots in the first and fifth cut showed that the changes after successive cuts are not only quantitative, but mainly qualitative. The detailed list of proteins identified in the first cut but absent in the fifth cut reported in the present study is relevant since it opens a perspective for the lines of research that employ biotic or abiotic elicitors to induce gene expression for essential proteins absents in sett roots of the fifth cut, increasing the agricultural productivity and longevity of cane fields.
