Natural infection of cape gooseberry (Physalis peruviana) by the potyvirus Tamarillo leaf malformation virus (TaLMV).

Acta Virol 2022 ;66(2):174-181

Tamarillo leaf malformation virus (TaLMV) is a potyvirus first discovered in cape gooseberry fields in Eastern, and South-western Antioquia. This virus is responsible for a very damaging disease that has resulted in significant reductions in yields and cultivated area for this crop in Colombia. Tamarillo is frequently co-cultivated with other solanaceous plants but no evidence for cross-pathogenicity of TaLMV has been found until now. Read More

Induction of Somatic Embryogenesis in Tamarillo ( Cav.) Involves Increases in the Endogenous Auxin Indole-3-Acetic Acid.

Plants (Basel) 2022 May 19;11(10). Epub 2022 May 19.

Center for Functional Ecology, Department of Life Sciences, University of Coimbra, 3000-456 Coimbra, Portugal.

Somatic embryogenesis (SE) is a complex biological process regulated by several factors, such as the action of plant growth regulators, namely auxins, of which the most physiologically relevant is indole-3-acetic acid (IAA). In tamarillo, an optimized system for induction of SE creates, after an induction process, embryogenic (EC) and non-embryogenic (NEC). In this work the endogenous levels of auxin along the induction phase and in the samples were investigated using chemical quantifications by colorimetric reactions and HPLC as well as immunohistochemistry approaches.

Elucidation of Endogenous Aroma Compounds in Tamarillo () Using a Molecular Sensory Approach.

J Agric Food Chem 2021 Aug 3;69(32):9362-9375. Epub 2021 Aug 3.

School of Chemical Sciences, The University of Auckland, Auckland 1010, New Zealand.

Glycosidically bound volatiles (GBVs) are flavorless compounds in fruits and may undergo hydrolysis during fruit maturation, storage, and processing, releasing free aglycones that are odor active. However, the contribution of glycosidic aglycones to the sensory attributes of fruits remains unclear. Herein, the key odor-active aglycones in tamarillo fruits were elucidated through the molecular sensory approach. Read More

Relationship between Volatile Composition and Bioactive Potential of Vegetables and Fruits of Regular Consumption-An Integrative Approach.

Molecules 2021 Jun 15;26(12). Epub 2021 Jun 15.

CQM-Centro de Química da Madeira, Universidade da Madeira, Campus Universitário da Penteada, 9020-105 Funchal, Portugal.

In recent years, there has been a growing interest in studying and exploring the potential health benefits of foods, mainly from vegetables and fruits from regular intake. The presence of secondary metabolites, namely polyphenols, carotenoids and terpenes, in certain food matrices seems to contribute to their functional properties, expressed through an increased prevention in the development of certain chronic diseases, namely coronary heart diseases, neurodegenerative diseases, cancer and diabetes. However, some foods' volatile secondary metabolites also present important bioactive properties, although this is a poorly scientifically explored field. Read More

Institute of Agriculture, University of Western Australia, Crawley, WA, Australia.

Forty-seven potato virus A (PVA) isolates from Europe, Australia, and South America's Andean region were subjected to high-throughput sequencing, and 46 complete genomes from Europe ( = 9), Australia ( = 2), and the Andes ( = 35) obtained. These and 17 other genomes gave alignments of 63 open reading frames 9,180 nucleotides long; 9 were recombinants. The nonrecombinants formed three tightly clustered, almost equidistant phylogroups; A comprised 14 Peruvian potato isolates; W comprised 37 from potato in Peru, Argentina, and elsewhere in the world; and T contained three from tamarillo in New Zealand.

Antioxidants (Basel) 2020 Apr 9;9(4). Epub 2020 Apr 9.

CQM-Centro de Química da Madeira, Universidade da Madeira, Campus Universitário da Penteada, 9020-105 Funchal, Portugal.

Fruits and vegetables are considered a good source of antioxidants, which are beneficial in protecting the human body against damage induced by free radicals and other reactive oxygen (ROS) and nitrogen (RNS) species. In this work, we aimed to evaluate the integral antioxidant activity (AOA) and determine individual polyphenols in fruits and vegetables of frequent consumption. For this purpose, an innovative and high throughput analytical approach based on original QuEChERS assisted by ultrasound extraction (USAE), instead of the manual agitation used in the classical procedure, was optimized and implemented for the isolation of polyphenols.
