“…As light is essential for plant growth and development, many components in photobodies have been showed to involve in numerous other pathways regulated by different environmental cues like plant hormones, temperature, nitric oxide, and many stresses [185][186][187][188][189][190][191][192][193][194][195][196]. Phytochrome-interacting factors (PIFs), one small subset of basic helix-loop-helix (bHLH) transcription factors, act as a cellular hub to intersect different signaling pathways [197][198][199].…”

“…In seeds, NO stimulates germination both under normal and stress conditions (Zhang et al, 2011;He et al, 2014;Pires et al, 2016), favors overcoming dormancy (Wang et al, 2015;Ma et al, 2016), promotes elongation and formation of adventitious roots (Schlicht et al, 2013;Bai et al, 2014) and enhances desiccation tolerance of recalcitrant seeds (Bai et al, 2011).…”

“…The protective of NO to recover the loss of seed viability and/or vigor role is based on its ability to regulate the level and toxicity of reactive oxygen species (ROS) (He et al, 2014). Application of exogenous NO in the form of SNP alleviates the adverse effects caused by heat, salt and drought stress, by decreasing hydrogen peroxide (H 2 O 2 ) and malondialdehyde (MDA) contents and modulating the activities of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and guaiacol peroxidase (GPX) (Lin et al, 2013;Filippou et al, 2013;Amooaghaie et al, 2015;Ma et al, 2016).…”

-Nitric oxide (NO) is a compound that participates in vegetable physiologic processes. The purpose of this study was to investigate the efficiency of sodium nitroprusside (SNP), a NO donor, on the physiologic and biochemical responses of Dalbergia nigra (bahia rosewood) seeds under storage in different environmental conditions. Seeds recently collected were stored in cold chamber (5 ºC and 60% relative humidity, RH) or in two desiccators at 20 ºC: 55 and 93% RH for four months. Every month of storage seed samples were taken and imbibed in SNP solution at 10 -4 M concentration for 48 hours or in water.The germination percentage, electric conductivity, lipid peroxidation and catalase enzyme activity were evaluated. Seeds of bahia rosewood stored in cold chamber at 55% RH maintained physiologic quality, while seeds imbibed in SNP reduced the membrane permeability, decreasing lipid peroxidation and increasing catalase activity. Seeds kept under 93% RH deteriorated quickly, and SNP was not efficient in revert the seed degradation. It was concluded that nitric oxide maintain the quality of seeds stored in cold chamber and at 20 ºC and 55% RH, by maintaining membrane integrity and stimulating catalase activity.Index terms: bahia rosewood, deterioration, forest seeds, nitric oxide.Manutenção da qualidade das sementes de Dalbergia nigra Vell. all. ex Benth durante o armazenamento por nitroprussiato de sódio RESUMO-Óxido nítrico (NO) é um composto que participa de inúmeros processos fisiológicos vegetais. O objetivo deste estudo foi investigar a eficiência de nitroprussiato de sódio (SNP), um doador de NO, na resposta fisiológica e bioquímica de sementes deDalbergia nigra (jacarandá-da-Bahia) sob armazenamento em diferentes condições ambientais. Sementes recém coletadas foram armazenadas em câmara fria (5 °C e 60% de umidade relativa, UR) ou em dois dessecadores a 20 °C: 55 e 93% UR por quatro meses. A cada 30 dias de armazenamento, foram embebidas em água ou em solução SNP 10 -4 M por 48 horas. Foram avaliadas a porcentagem de germinação, a condutividade elétrica, a peroxidação lipídica e a atividade da enzima catalase. Sementes de jacarandá-da-Bahia armazenadas em câmara fria e a 20 ºC e 55% UR mantiveram sua qualidade fisiológica, e quando embebidas em SNP foi observada redução na permeabilidade da membrana, diminuindo a peroxidação lipídica e aumentando a atividade da catalase. Sementes mantidas sob 93% UR deterioraram rapidamente, e SNP não foi eficiente em reverter a degradação. Concluiu-se que o óxido nítrico manteve a qualidade das sementes armazenadas em câmara fria e a 20 ºC e 55% UR, mantendo a integridade da membrana e estimulando a catalase.Termos para indexação: jacarandá-da-Bahia, deterioração, sementes florestais, óxido nítrico.

“…This process leading to the development of autotrophic metabolism requires the ability to light response. Light-dependent Arabidopsis seed germination is mediated by photoreceptors, mostly phytochromes (PHY), that perceive Red/Far-Red radiation (Sullivan and Deng 2003;Bai et al 2014). It was demonstrated that NO fumigation substituted red light effect in photoblastic seeds and stimulated deetiolation of Arabidopsis seedlings (Giba et al 1998;Beligni and Lamattina 2000).…”

“…NO involvement in photomorphogenesis positively affected DELLA protein accumulation and negatively affected expression of one of the GA signaling component Phytochrome-Interacting Factor (PIF) in Arabidopsis seedlings (Lozano-Juste and León 2011). PIF proteins, including PIF3 is known to interact with PHY, while DELLA proteins are involved in inhibition of hypocotyls growth by decrease of PIF transcription activity (Bai et al 2014 and citation therein). Thus, it suggests interplay of PHY, GA, and NO as NO inhibited primary root growth of Arabidopsis seedlings throughout a reduction of PIF3 expression (Bai et al 2014).…”
