Herbicides are stressors that can have negative effects on plants. In Oryza sativa (L.), differential gene expression may be evalu-ated through real-time reverse transcription quantitative poly-merase chain reaction (RT-qPCR). The aim of this study was to evaluate the stability of candidate reference genes and to quan-tify the relative expression of oxidative stress genes at different times (12, 24, 48, and 96 hours after treatment [HAT]) with penoxsulam, cyhalofop-butyl, and bentazon herbicides. Norm-Finder, BestKeeper, and GeNorm software and the compara-tive ∆Ct method were used to assess expression stability and to determine the RT-qPCR threshold values of the candidate reference genes. The UBQ5 gene was the most stable among the reference genes analyzed. The gene expression results showed upregulation of OsCAT and OsMnSOD1 genes at all times after herbicide application. The OsA PX 2 and OsGST3 genes showed increased gene expression at 12 and 96 HAT for all herbicides. The OsHO -1 gene had the most significant expression changes, with maximum expression levels at 24 HAT with bentazon and at 96 HAT with penoxsulam and cyhalofop-butyl. Overall, antioxidant system gene expression increased after the applica-tion of bentazon, penoxsulam, and cyhalofop-butyl in rice |

Abstract - The objective of this work was to evaluate the morphogenetic, structural, physiological, and productive traits of forage peanut (Arachis pintoi) subjected to different levels of artificial shading in the field. The 'Amarillo MG-100' forage peanut was planted in April 2015, and the evaluations were carried out from May 2017 to April 2018. The treatments were: 0, 30, 45, and 75% of artificial shading. There was no significant effect of shading on the morphogenetic traits of forage peanut. Shading increased final leaf length and canopy height and decreased the leaf area index and number of stolons. Photosynthesis, transpiration rate, stomatal conductance, chlorophyll b, and leaf temperature increased quadratically as a function of shading. There was a linear positive effect on the growing cycle length and a quadratic effect on the production of dry matter mass, with the maximum at 30% shade. Forage peanut harvested at 95% light interception (11-cm height) shows adaptation to shading up to 45%, with increased leaf size, canopy height, photosynthetic rate, stomatal conductance, transpiration rate, and chlorophyll b. In addition, plants at 30% shading show a higher yield than those growing under full sun. Resumo - O objetivo deste trabalho foi avaliar as características morfogenéticas, estruturais, fisiológicas e produtivas do amendoim‑forrageiro submetido a diferentes níveis de sombreamento artificial no campo. O amendoim-forrageiro 'Amarillo MG-100' foi plantado em abril de 2015, e as avaliações foram realizadas de maio de 2017 a abril de 2018. Os tratamentos foram: 0, 30, 45 e 75% de sombreamento artificial. Não houve efeito significativo do sombreamento sobre as características morfogenéticas do amendoim-forrageiro. O sombreamento aumentou o comprimento final da folha e a altura do dossel e diminuiu o índice de área foliar e o número de estolões. A fotossíntese, a taxa de transpiração, a condutância estomática, a clorofila b e a temperatura das folhas aumentaram quadraticamente em função do sombreamento. Houve efeito linear positivo sobre o tamanho do ciclo de crescimento e efeito quadrático sobre a produção de massa de matéria seca, com o máximo a 30% de sombra. O amendoim-forrageiro colhido a 95% de interceptação luminosa (11 cm de altura) apresenta adaptação ao sombreamento de até 45%, com aumento do tamanho das folhas, da altura do dossel, da taxa fotossintética, da condutância estomática, da taxa de transpiração e da clorofila b. Além disso, as plantas sob sombreamento de 30% apresentam maior rendimento do que aquelas que crescem sob a luz do sol.
