With the growing interest of society in healthy eating, fresh, ready-to-eat, functional food, such as microscale vegetables (sprouted seeds and microgreens), has been on rise recent years globally. This review briefly describes crops commonly used for vegetable production, highlights Brassica because their health-promoting secondary metabolites (polyphenols, glucosinolates), looks at consumer acceptance sprouts microgreens. Apart from main landraces, wild food plants, crops’ relatives often have high phytonutrient density exciting flavors tastes, thus providing scope to widen range species this purpose. Moreover, nutritional value content phytochemicals vary with plant growth development within same crop. Sprouted microgreens are more nutrient-dense than ungerminated or mature vegetables. also environmental priming factors that may impact These include environment, substrates, imposed stresses, seed biostimulants, biofortification, effect light controlled environments. touches microgreen market trends. Due short cycle, can be produced minimal input; without pesticides, they even home-grown harvested needed, hence having low impacts a broad among health-conscious consumers.

Mechanistic Insights of Plant Growth Promoting Bacteria Mediated Drought and Salt Stress Tolerance in Plants for Sustainable Agriculture

International Journal of Molecular Sciences, Journal Year: 2022, Volume and Issue: 23(7), P. 3741 - 3741

Published: March 29, 2022

Climate change has devastating effects on plant growth and yield. During ontogenesis, plants are subjected to a variety of abiotic stresses, including drought salinity, affecting the crop loss (20–50%) making them vulnerable in terms survival. These stresses lead excessive production reactive oxygen species (ROS) that damage nucleic acid, proteins, lipids. Plant growth-promoting bacteria (PGPB) have remarkable capabilities combating salinity stress improving growth, which enhances productivity contributes food security. PGPB inoculation under promotes through several modes actions, such as phytohormones, 1-aminocyclopropane-1-carboxylic acid deaminase, exopolysaccharide, siderophore, hydrogen cyanide, extracellular polymeric substances, volatile organic compounds, modulate antioxidants defense machinery, abscisic thereby preventing oxidative stress. also provide osmotic balance; maintain ion homeostasis; induce salt-responsive genes, metabolic reprogramming, transcriptional changes transporter etc. Therefore, this review, we summarize mitigate its detrimental effects. Furthermore, discuss mechanistic insights towards tolerance for sustainable agriculture.

Exogenous Gibberellic Acid or Dilute Bee Honey Boosts Drought Stress Tolerance in Vicia faba by Rebalancing Osmoprotectants, Antioxidants, Nutrients, and Phytohormones

Plants, Journal Year: 2021, Volume and Issue: 10(4), P. 748 - 748

Published: April 11, 2021

The use of growth regulators such as gibberellic acid (GA3) and biostimulants, including diluted bee honey (Db-H) can improve drought tolerance in many crops, the faba bean (Vicia L.). Db-H contains high values osmoprotectants, mineral nutrients, vitamins, antioxidants making it an effective regulator against environmental stress effects. Therefore, present study was planned to investigate potential improvement plant performance (growth productivity) under full watering (100% crop evapotranspiration (ETc)) (60% ETc) by foliar application GA3 (20 mg L−1) or g L−1). ameliorative impacts these on growth, productivity, physio-biochemical attributes, nutrient status, antioxidant defense system, phytohormones were evaluated. attenuated negative influences cell membrane stability, ion leakage, relative water content, leaf pigments related photosynthesis (chlorophylls carotenoids), efficiency photosystem II (PSII terms Fv/Fm index), thus improving green pod yield, efficiency. Drought caused abnormal state nutrients photosynthetic machinery due increased indicators oxidative (malondialdehyde (MDA), hydrogen peroxide (H2O2) superoxide (O2•−)), associated with osmoprotectants (proline, glycine betaine, soluble sugars, protein), non-enzymatic (ascorbic acid, glutathione, α-tocopherol), enzymatic activities (superoxide dismutase, catalase, glutathione reductase, ascorbate peroxidase). However, foliar-applied mediated further increases capacity, GA3, indole-3-acetic cytokinins, along decreased levels MDA abscisic acid. These results suggest at tested concentrations mitigate drought-induced damage plants obtain satisfactory productivity a deficit up 40%.
