Carotenoids are well-known physical quenchers of chlorophyll excited states and reactive oxygen species both in vivo and in vitro. They may also be involved in chemical quenching undergoing, e.g. isomerizations or oxidations. We have found that beta-carotene (Car) in aerobic acetone is rapidly oxygenated under strong illumination with red light (lambda exc > or = 630 nm) in the presence of bact...

Relative poverty lines such as one-half median income have been increasingly used in poverty studies. This paper contributes to the literature by developing statistical inference for testing decomposable poverty measures with relative poverty lines. The poverty lines we consider are percentages of mean income and percentages of quantiles. We show that the estimates of poverty indices with relat...

Carotenoids are C40 tetraterpenoids synthesized by nuclear-encoded multienzyme complexes located in the plastids of higher plants. To understand further the components and mechanisms involved in carotenoid synthesis, we screened Arabidopsis for mutations that disrupt this pathway and cause accumulation of biosynthetic intermediates. Here, we report the identification and characterization of two...

The influence of mixing alfalfa with whole-plant corn in different proportions on the fermentation characteristics and bacterial community silage was investigated. Alfalfa corn, harvested at dry matter content 276.47 328.43 g/kg fresh weight, accordingly, were chopped to approximately 2 cm mixed ratios 100:0 (C0, control), 80:20 (C20), 60:40 (C40), 40:60 (C60), 20:80 (C80) 0:100 (C100) a weight...

Existen pocos estudios en tomate (Solanum lycopersicum L.) sobre el efecto de la temperatura alta durante desarrollo semilla. El objetivo esta investigación fue evaluar parámetros calidad física y fisiológica semillas frutos desarrollados diferentes etapas su desarrollo. La variedad nativa Campeche 40 (C40), Money Maker (MM) línea experimental L52 se sembraron primavera 2020 utilizando dos secc...
