Abstract Tomato (Solanum lycopersicum) is a perishable fruit because of its fast water loss and susceptibility to pathogens in the post-harvest stage, which leads to huge economic losses every year. In this study, firstly from 19 tomato cultivars, we screened out two cultivars, Riogrand and SalarF1, having long and short shelf-life spans, respectively. Secondly, shelf-life analysis was carried out for both cultivars at room temperature. Results exhibited that Riogrand showed higher firmness and less weight loss than SalarF1. The ethylene production was higher in SalarF1, compared with Riogrand during post-harvest storages. We performed transcriptomic analysis of both… More >

Abstract Salt stress inhibits plant growth and affects the biosynthesis of its secondary metabolites. Flavonoids are natural compounds that possess many important biological activities, playing a significant role in the medicinal activity of Eucommia ulmoides (E. ulmoides). To investigate the mechanism by which salt stress affects the biosynthesis of flavonoids in E. ulmoides, a comprehensive analysis of metabolomics and transcriptomics was conducted. The results indicated that salt stress led to the wilting and darkening of E. ulmoides leaves, accompanied by a decrease in chlorophyll levels, and significantly induced malondialdehyde (MDA) and relative electrical conductivity. During salt stress, most metabolites in… More >

Abstract Livestock grazing has a significant impact on natural grasslands, with approximately one-third of the world’s land area dedicated to this industry. Around 20% of global grasslands are highly degraded due to overgrazing, affecting their productivity and conservation capacity. Best practices are required to ensure sustainable livestock production that supports biodiversity. The Intermediate Disturbance Hypothesis (IDH) suggests that environments with moderate levels of disturbance exhibit a higher species diversity. Moderate grazing can reduce the dominance of certain species, thereby enhancing plant diversity. However, concerns arise regarding the increase of exotic and unpalatable species under moderate grazing… More >

Abstract Argentina is the country with the highest proportion of arid and semi-arid ecosystems in Latin America. In the rangelands of Southwestern Buenos Aires (Patagones Department), there is a clear advancement of the agricultural frontier to the detriment of the native forest in this region. Due to rainfall variation and seed acquisition, Thinopyrum ponticum is cultivated as a forage perennial crop in this region. Our objective was to evaluate the performance of T. ponticum as a facilitating crop for the medium-term rehabilitation of natural grasslands in semi-arid areas. The working hypotheses were that: 1) native perennial grass cover… More >

Abstract The semiarid grasslands of Argentina’s central region have been modified by domestic livestock grazing, both in their composition and structure. The increase in the proportion of woody and non-forage species and the decrease in forage species are some of the most evident results of this process. There is limited available information about the effect of differential grazing pressures on morphometric attributes of native species, and it also depends on the life histories of the species in this grassland. The objective of this work was to evaluate some morphometric aspects in the grasses Poa ligularis Nees ex… More >

Abstract Despite hybrid dominance contributing to the genetic improvement of crops, little is known about heterosis and inheritance patterns of endogenous substances in sorghum (Sorghum bicolor (L.) Moench) root bleeding sap. In this study, six sterile and six restorer lines of sorghum and 36 hybrid sorghum combinations formulated as incomplete double-row crosses were selected as test materials, and heterosis, combining ability, heritability, and their interrelationships of root bleeding sap endogenous substances in different hybrid sorghum combinations and their parents were investigated. The results showed that the root bleeding sap of the F1 generation of hybrid sorghum had… More >

Abstract The ATP-binding cassette (ABC) transporter is a gene superfamily in plants. ATP-binding cassette subfamily C (ABCC) protein is a multidrug resistance-associated (MRP) transporter. They play various roles in plant growth, development, and secondary metabolite transport. However, there are few studies on ABCC transporters in tea plants. In this study, genome-wide association study (GWAS) analysis of epigallocatechin gallate (EGCG) content in 108 strains of Kingbird revealed that CsABCCs may be involved in EGCG transport. We identified 25 CsABCC genes at the genomic level of the tea plant, their phylogenetic tree, gene structure, targeted miRNA and other bioinformatics… More >

Abstract The effects of the salt stress on plant growth are usually increased by the water stress. We studied the impact of both stresses in simultaneous pulses of drought and salinity on Paspalum dilatatum. This forage species is native to South America, spread in grasslands in many tropical, subtropical, and temperate areas of the world, and very common in grasslands of the Flooding Pampas of Argentina. Mimicking what happens in nature. We compared a pot experiment, a non-stressed control against water stress for a month (midpoint between field capacity and wilting point), and two saline stresses (moderate,… More >

Abstract Genes in the glycogen synthase kinase 3 (GSK3) family are essential in regulating plant response to stressful conditions. This study employed bioinformatics to uncover the GSK3 gene family from the sunflower genome database. The expressions of GSK3 genes in different tissues and stress treatments, such as salt, drought, and cold, were assessed using transcriptome sequencing and quantitative real-time PCR (qRT-PCR). The study results revealed that the 12 GSK3 genes of sunflower, belonging to four classes (Classes I–IV), contained the GSK3 kinase domain and 11–13 exons. The majority of GSK3 genes were highly expressed in the leaf axil and… More >

Abstract Salvia officinalis L. (Lamiaceae) leaves and its essential oil is used for mouth and throat disorders, skin disorders, minor wounds, and gastrointestinal disorders, and is widely used worldwide. The research aimed to conduct a comparative study of the composition of S. officinalis essential oils from commercial samples, and their main chemotypes. The volatile constituents from S. officinalis leaves were investigated using gas chromatography (GC). The commercial samples of sage leaves were obtained from retail pharmacies in nine mainly European countries. The yield of essential oil in S. officinalis commercial leaves was between 10.0 and 24.8 mL/kg. The principal components More > Graphic Abstract
