Abstract. Background: A major limiting factor for plant growth is the aluminum (Al) toxicity in acidic soils, especially in tropical regions. The exclusion of Al from the root apex through root exudation of organic acids such as malate and citrate is one of the most ubiquitous tolerance mechanisms in the plant kingdom. Two families of anion channels that confer Al tolerance are well described in the literature, ALMT and MATE family. Results: In this study, sugarcane plants constitutively overexpressing the Sorghum bicolor MATE gene (SbMATE) showed improved tolerance to Al when compared to non-transgenic (NT) plants, characterized by sustained root growth and exclusion of aluminum from the root apex based on the result obtained with hematoxylin staining. In addition, genome-wide analysis of the recently released sugarcane genome identified 11 ALMT genes and molecular studies showed potential new targets for aluminum tolerance. Conclusions: Our results indicate that the transgenic plants overexpressing the Sorghum bicolor MATE has an improved tolerance to Al. The expression profile of ALMT genes revels potential candidate genes to be used has an alternative for agricultural expansion in Brazil and other areas with aluminum toxicity in poor and acid soils. |

Magnaporthe oryzae (Mo) damages rice leaf, and Thichoderma asperellum (Ta) is a potential biological agent against rice blast. The aims were to identify a reduction of leaf blast severity (LBS), induction of biochemical defense, growth promotion, physiological changes, and modulation of four genes, promoted by four Ta isolates and Ta pool (mixed four Ta isolates). Assay 1 (A1) tested Ta, applied by soil drenched (D) or foliar spraying (S), and evaluated LBS and enzyme activity after challenge inoculation (ChI). Assay 2 (A2) detected growth promotion and physiological changes (A, E, gs, and WUE) when Ta was applied by seed treatment (ST). In assay 3 (A3), plants were treated with Ta by D and S and evaluated after ChI for physiological changes, total chlorophyll content, antioxidant enzymes, and gene expression. In A1, all treatments suppressed leaf blast, and Ta (Ufra.T06) promoted CHI, GLU, LOX, and PAL activities in all applications form. In A2, the Ta pool promoted increases of 52%, 12,24%, 90%, and 40% in A, E, gs, and WUE, respectively. In A3, the Ta pool suppressed LBS by 89% and modulated J10sPR10 and LOX-RLL expression by increasing 35% and 474%, respectively. Ta pool is a stable combination for a multiple function biological agent and should be inserted in integrated rice management. |
