Heterosis in crosses between remnant populations of the rare prairie forb Silene regia: Implications for restoration genetics. [PDF]

Am J Bot
Abstract Premise Calls to adopt seed‐sourcing strategies in biological restoration that preserve local adaptation while maximizing genetic variation (e.g., regional admixture provenancing) are increasingly common. Heterosis, the increased fitness of progeny from crosses between populations relative to progeny from crosses within populations, could ...

Physicochemical and Thermal Evaluation of a Mixed-Mode Greenhouse Solar Dryer for Guava (Psidium guajava L.). [PDF]

J Food Sci
ABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...

Microbe-induced resistance involves priming of direct or indirect defenses according to the stage of herbivory. [PDF]

New Phytol
Summary Microbe‐induced resistance (MIR) encompasses a broad range of plant responses that mediate both direct and indirect defenses against herbivores. However, previous studies have addressed MIR in relation to either direct or indirect defenses in isolation, overlooking potential conflicts or synergies that may arise between MIR‐elicited defense ...

Can heterosis and inbreeding depression explain the maintenance of outcrossing in a cleistogamous perennial?

American Journal of Botany, Volume 110, Issue 10, October 2023., 2023
Abstract Premise What maintains mixed mating is an evolutionary enigma. Cleistogamy—the production of both potentially outcrossing chasmogamous and obligately selfing cleistogamous flowers on the same individual plant—is an excellent system to study the costs of selfing.

Energy analysis of drying basil (Ocimum basilicum) leaves in an active greenhouse solar dryer

Journal of Food Process Engineering, Volume 46, Issue 3, March 2023., 2023
Abstract The need for better utilization of solar greenhouses during summer in the hot climate conditions of Mexico led to the development of the concept of active greenhouse solar dryers. The objective of this research was energy analysis of an active greenhouse solar dryer for basil leaves drying.

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on sustainable dietary and physical activity recommendations for the Spanish population

Food Risk Assess Europe, Volume 1, Issue 1, March 2023., 2023
Abstract Dietary recommendations are developed from the best available scientific evidence on the effect of nutrients and food on health. These recommendations take into account that the effect of food depends not only on its nutritional content but also on the matrix in which is ingested, the alterations during the culinary process, the presence of ...
