Heat-Priming during Somatic Embryogenesis Increased Resilience to Drought Stress in the Generated Maritime Pine () Plants.

Drought stress is becoming the most important factor of global warming in forests, hampering the production of reproductive material with improved resilience. Previously, we reported that heat-priming maritime pine () megagametophytes during SE produced epigenetic changes that generated plants better adapted to subsequent heat stress. In this work, we tested, in an experiment performed under greenhouse conditions, whether heat-priming will produce cross-tolerance to mild drought stress (30 days) in 3-year-old priming-derived plants.

Untargeted Metabolomics of Rind Essential Oils Allowed to Differentiate Two Closely Related Clementine Varieties.

Chemical characterization of clementine varieties ( Hort. ex Tan.) essential oils (EO) can lead to variety identification and valorization of their potential use in food and aroma industries.

Carotenoid composition and vitamin A value in ají (Capsicum baccatum L.) and rocoto (C. pubescens R. & P.), 2 pepper species from the Andean region.

The carotenoid patterns of fully ripe fruits from 12 Bolivian accessions of the Andean peppers Capsicum baccatum (ají) and C. pubescens (rocoto) were determined by high-performance liquid chromatography (HPLC)-photodiode array detector (PDA)-mass spectrometry (MS). We include 2 California Wonder cultivars as C.
