cis-jasmone is a naturally-occurring compound in plants that activates direct and indirect defence in model and crop plants'". Exogenous application of cis-jasmone increases flavonoid concentrations in soybean and affects negatively Anticarsia gemmatalis weight gain. Here, foliar isoflavonoid concentrations were evaluated after cis-jasmone spraying on soybean cultivars BRS l34 and lAC 100, grown at Embrapa Soybean greenhouse facilities. At V) development stage, plants were sprayed with water, Tween 20 + water or cis-jasmone + tween 20 + water. For flavonoid extraction, leaves were collected 12, 24, 48, 96, and 120h after spraying, and immediately frozen in liquid nitrogen, ground in a mortar and extracted in MeOH 90% or EtOH 80% + HCI (0.001 M). Isoflavonoid concentrations were estimated by HPLC analysis. The extracts obtained from leaves of both genotypes of 24 h cis-jasmone treated plants presented higher quantities of daidzin, malonyl-daidzin, glycitin, malonyl-glycitin, glycitein and genistin, when compared to water and Tween 20 + water treated plants. Daidzein was present in hígh concentration, in both cultivars, 24 h and 48 h after cis-jasmone spraying, but no longer detected in samples collected 120 h after treatment. Coumesterol was detected, but only from samples collected 48 h after spraying. It is possible that such increases may be related to the decrease in daidzein concentration, considering that this compound is involved in coumesterol synthesis. Comparing solvent efficiencies, EtOH 80% + HCI (0.001 M) presented higher extraction capacity than MeOH 90%; coumestrol concentration in ethanolic extracts was approximately twice as high as in methanolic extracts. Our results indicated that cis-jasmone induces the production of non-volatile compounds in soybean such as isoflavonoids, and that EtOH 80% + HCI (O.OOIM)extraction is more efficient when compared to MeOH 90%.

Aims Urochloa species are the most planted forage used for cattle production in the tropics. Plant-bacteria interaction is cultivar dependent, and a better understanding of this fine-tuning can be useful to improve the plant growth benefits of this association. Therefore, the current study aimed at testing the performance of six Urochloa cultivars inoculated with α (Azospirillum baldaniorum AbSp245 and Nitrospirillum amazonense NCBAmC) and β (Herbaspirillum seropedicae HsHRC54) Proteobacteria by evaluating plant initial growth and root colonization. |
