“…However, it is further noteworthy that despite similar treatments, HA-grown Brassicaceae vegetable samples showed a significantly higher boost in the TPC content than LA-grown vegetables. Plants at higher elevations are exposed to abiotic stresses like overwhelmingly intense UV-B radiation, which has a wide range of effects on plant growth, morphology, and physiology especially triggering different defensive mechanisms which also includes production of polyphenolic secondary metabolites 28 , 29 . There are few reports such as by Kumar et al 8 where it found that extract of Eruca sativa samples from high altitude had more phenolic content as compared to low altitude samples.…”

High-altitude (HA) environment presents immense physiological adversities for humans that have been overcome by supplementing bio-active phytochemicals from functional foods that support and accelerate acclimatization under these extreme environmental conditions. Several agricultural interventions have been investigated to enhance the phytochemical content in vegetables however; these studies have been limited to low-altitude (LA) regions only. In view of an existing knowledge gap, current work is designed to compare the phytochemical compositions of HA and LA-grown Brassicaceae vegetables (cabbage, cauliflower, knol-khol, and radish) using organic treatments via farm yard manure (FYM) and Azotobacter. The open field study was conducted as a two-factorial randomized block design. The first factor was treatment (T1-FYM, T2-Azotobacter, T3-FYM + Azotobacter, and T4-control) while the second was locations (HA and LA). Among all these treatments, the application of treatment T3 in HA-grown cabbage showed the highest total phenolic content (TPC; 9.56 μg/mg), total flavonoids content (TFC; 14.48 μg/mg), and antioxidant potential using 2,2-diphenyl-1-picrylhydrazyl (DPPH; 85.97%) and ferric reducing antioxidant power (FRAP; 30.77 μg/mg) compared to LA grown samples. Reverse Phase high performance liquid chromatography (RP-HPLC) analysis showed that treatment T3 at HA led to significantly high kaempferol (0.92 μg/mg) and sulforaphane (8.94 μg/mg) contents in cabbage whereas, indole-3-carbinol (1.31 μg/mg) was higher in HA grown cauliflower. The present study provides scientific evidence for the enrichment of health-promoting phytochemical compounds in Brassicaceae vegetables grown with T3 treatment specifically at HA.

Objetivo: establecer el estado del arte de los enjuagues bucales, en relación al control químico del biofilm oral y efectos no deseados en la cavidad oral. Materiales y Métodos: se realizó una búsqueda electrónica en las siguientes bases de datos: Pubmed, Clinical key, Dentistry & Oral Science Source, Science direct y Scopus, utilizando las palabras clave: “dental plate, chemical control, dental plate and chemical control”. Se incluirán en la revisión los artículos que tienen los enjuagues bucales como enfoque principal hoy y aquellos que pueden destacarse en el futuro. Resultados: se consiguió un total de 260 documentos. Después de seleccionar el uso de los criterios de inclusión, se utilizaron para el análisis un total de 7 documentos de texto completo. Conclusión: el desarrollo y la aplicación clínica de los antisépticos orales requieren de investigación aplicada para resolver los problemas cotidianos de los pacientes. Los enjuagues que involucran un componente natural como principio activo han demostrado, según los estudios incluidos, un buen porcentaje de inactivación de la patogenia del biofilm oral, por lo que futuros estudios deberán reorientarse en estos, allanando el camino a productos naturales que reduzcan el porcentaje de efectos adversos en la cavidad bucal.

“…Being more favorable in taste than most other brassicas and comprising a large variety of functional compounds, it is not surprising that kohlrabi has been recently receiving more and more attention both as food and feed [3]. In this context, the number of studies on ex vitro grown kohlrabi has increased, including studies on the metabolism of phenolic compounds and glucosinolates [8,12], their antioxidant and antimicrobial potential [13], biosynthesis of anthocyanin [14,15], effects of plant growth regulators and various means of biofortification on growth, yield, and quality traits of kohlrabi [16][17][18], as well as reports on transcriptomic [19,20] and hormonomic [21] analysis of stem tuber formation.…”

In Vitro Growth and Regeneration of Brassica oleracea var. gongylodes: A Decade of Research

Kohlrabi (Brassica oleracea var. gongylodes) is a vegetable cultivated for its edible stem tuber. Although valued for its nutritional properties and tolerance to abiotic stress, kohlrabi is one of the least studied brassicas. In this review, we summarize the results of our decade-long research on in vitro morphogenesis of kohlrabi, starting from 2013. Protocols for efficient in vitro regeneration with minimal requirements for external application of plant growth regulators (PGRs) have been developed, both by somatic embryogenesis (SE) and by de novo shoot organogenesis (DNSO). Efficient regeneration by direct SE was achieved using immature zygotic embryos as explants incubated on PGR-free media, and the production process was maintained in culture thanks to highly efficient secondary SE. Conversely, efficient regeneration by indirect DNSO was achieved using entire seedlings as explants and adding only cytokinin (CK) without the need for exogenous auxin. Comprehensive phytohormone analyses revealed that different exogenously applied CKs differentially affected the composition of endogenous phytohormones and induced changes in the expression of cell cycle-related genes and other genes involved in the organogenic response. The addition of high sucrose concentrations to the nutrient media failed to induce the formation of stem tubers in in vitro culture, but revealed a complex interaction with exogenously applied CKs, interfering with both the endogenous phytohormonome and the expression of organogenesis-related genes. Our work has provided substantial biotechnological advances in the field of in vitro regeneration of kohlrabi, as well as in understanding the underlying phytohormonal regulation. The review aims to introduce kohlrabi to the scientific community as a model system for both basic and applied research, while we continue seeking answers to the outstanding questions and trying to pave the way for the development of more resistant varieties.
