ABSTRACT - The objective of this work was to evaluate inoculation response to Azospirillum baldaniorum strain Sp245 in 14 Urochloa cultivars. The evaluated cultivars were: Marandú, Xaraés, Paiaguás, Piatã, Basilisk, B140, Comum, Tupi, H47, Llanero, Ruziziensis, Ipyporã, Mulato, and Convert HD364. Three experiments were conducted to measure root traits: two using soil and one a sterile substrate. Compared with the control, a single application of A. baldaniorum Sp245 increases dry matter accumulation and number of roots in cultivars Marandú, Llanero, Ruziziensis, and Convert HD364. However, after inoculation, cultivars Xaraés and Ipyporã show some root traits with lower values. RESUMO - O objetivo deste trabalho foi avaliar a resposta à inoculação da estirpe Sp245 de Azospirillum baldaniorum em 14 cultivares de Urochloa. As cultivares avaliadas foram: Marandú, Xaraés, Paiaguás, Piatã, Basilisk, B140, Comum, Tupi, H47, Llanero, Ruziziensis, Ipyporã, Mulato e Convert HD364. Foram conduzidos três experimentos para mensuração de parâmetros radiculares: dois em solo e um em substrato estéril. Em comparação ao controle, a aplicação única de A. baldaniorum Sp245 aumenta o acúmulo de massa seca e a quantidade de raízes das cultivares Marandú, Llanero, Ruziziensis e Convert HD364. No entanto, após a inoculação, as cultivares Xaraés e Ipyporã apresentam alguns parâmetros radiculares com valores menores. |

Hormones are likely to be important factors modulating the light-dependent anthocyanin accumulation. Here we analyzed anthocyanin contents in hypocotyls of near isogenic Micro-Tom (MT) tomato lines carrying hormone and phytochrome mutations, as single and double-mutant combinations. In order to recapitulate mutant phenotype, exogenous hormone applications were also performed. Anthocyanin accumulation was promoted by exogenous abscisic acid (ABA) and inhibited by gibberellin (GA), in accordance to the reduced anthocyanin contents measured in ABA-deficient (notabilis) and GA-constitutive response (procera) mutants. Exogenous cytokinin also enhanced anthocyanin levels in MT hypocotyls. Although auxin-insensitive diageotropica mutant exhibited higher anthocyanin contents, pharmacological approaches employing exogenous auxin and a transport inhibitor did not support a direct role of the hormone in anthocyanin accumulation. Analysis of mutants exhibiting increased ethylene production (epinastic) or reduced sensitivity (Never ripe), together with pharmacological data obtained from plants treated with the hormone, indicated a limited role for ethylene in anthocyanin contents. Phytochrome-deficiency (aurea) and hormone double-mutant combinations exhibited phenotypes suggesting additive or synergistic interactions, but not fully espistatic ones, in the control of anthocyanin levels in tomato hypocotyls. Our results indicate that phytochrome-mediated anthocyanin accumulation in tomato hypocotyls is modulated by distinct hormone classes via both shared and independent pathways.
