Several protocols and commercial kits are used for the extraction of nucleic acids from different plant tissues. Although there are several procedures available to remove sugars, which hinder the extraction of clean genomic DNA, there are few to assist with extraction of RNA. Those presently used include precipitations with ethylene glycol monobutyl ether or lithium chloride (LiCl), or centrifugation in cesium chloride (CsCl) gradients, but these generally either do not allow high recovery of RNA, are time consuming, rely on hazardous chemicals or need special equipment. Here we present the use of the simple cation, Ca2+, which has been tested and shown to be very efficient for the precipitation of high molecular weight pectic sugars during RNA extraction. Results are presented for different plant tissues, especially tissues of peach and apple fruits at varying ripening stages.

Can We Maintain Muscle Mass on a Plant-Based Diet?
Curr Nutr Rep
January 2025
Department of Internal Medicine, Mayo Clinic, Rochester, MN, USA.
Purpose Of Review: This review aims to determine whether muscle mass and function can be effectively maintained without relying on animal-based protein sources. We evaluate the quality, digestibility, and essential amino acid profiles of plant-based proteins to understand their potential in preventing and managing sarcopenia.
Recent Finding: Recent studies indicate that while animal-based proteins have traditionally been considered the gold standard for supporting muscle protein synthesis, certain plant-based protein blends, fortified with leucine or other essential amino acids, can produce comparable anabolic responses.
Dietary purslane (Portulaca oleracea L.) leaf powder maintains growth and intestinal health in Oreochromis niloticus under chronic water-borne cadmium exposure by strengthening the gut barriers, modulating the intestinal nutrient transporters, and relieving oxidative stress.

Phenomic selection based on parental spectra can be used to predict GCA and SCA in a sparse factorial design. Prediction approaches such as genomic selection can be game changers in hybrid breeding. They allow predicting the genetic values of hybrids without the need for their physical production.

Background/aim: L. () is an aromatic medicinal species with important nutraceutical potential, having rosmarinic acid (RA) as one of its main metabolites. The present study aims to evaluate the effects of an extract obtained from the leaves of this species and of its main metabolite in improving the streptozotocin-induced damage of hearts and aorta of diabetic rats.
