“…Brassinosteroids (BRs) are plant steroid hormones, which play essential roles in plant growth and development 1 2 , and also confer tolerance to a wide range of abiotic stresses 3 4 . The BR signalling pathway is one of the best-understood signal transduction pathways in the plant hormone field.…”

“…BR activated signalling by BRI1 inactivates the negative regulator BRASSINOSTEROID INSENSITIVE2 (BIN2), which in turn leads to activation of two closely related transcription factors BRI1-EMS SUPPRESSOR1 (BES1) and BRASSINAZOLE-RESISTANT1 (BZR1) and expression of an array of BR-regulated genes 5 6 . BAK1 and its homologs are also a required component of pathogen/microbe-associated molecular patterns (PAMPs/MAMPs)-triggered immunity and Mi-1-mediated resistance to insect herbivores 1 2 .…”

As a resource allocation strategy, plant growth and defense responses are generally mutually antagonistic. Brassinosteroid (BR) regulates many aspects of plant development and stress responses, however, genetic evidence of its integrated effects on plant growth and stress tolerance is lacking. We overexpressed the Arabidopsis BR biosynthetic gene AtDWF4 in the oilseed plant Brassica napus and scored growth and stress response phenotypes. The transgenic B. napus plants, in comparison to wild type, displayed increased seed yield leading to increased overall oil content per plant, higher root biomass and root length, significantly better tolerance to dehydration and heat stress, and enhanced resistance to necrotrophic fungal pathogens Leptosphaeria maculans and Sclerotinia sclerotiorum. Transcriptome analysis supported the integrated effects of BR on growth and stress responses; in addition to BR responses associated with growth, a predominant plant defense signature, likely mediated by BES1/BZR1, was evident in the transgenic plants. These results establish that BR can interactively and simultaneously enhance abiotic and biotic stress tolerance and plant productivity. The ability to confer pleiotropic beneficial effects that are associated with different agronomic traits suggests that BR–related genes may be important targets for simultaneously increasing plant productivity and performance under stress conditions.

“…Owing to its multiple effects, it can be used in horticulture to improve growth, yield and quality. In recent, this hormone was proved as a natural, nontoxic, and safe to environment, thus it may be used in horticultural crops to improve the quality of the produce [73]. There is several evidence that it acts as growth promoter in plants either solely or in combination with other hormones like GA3, jasmonic acid and polyamines.…”

Fruits are an important component of our diet. Postharvest quality retention during supply chain management is a major concern and has become a priority of today's world. Owing to this, food security is a big challenge and, to mitigate this nutritional, security is a major task. The existing technologies have brought about several desirable changes in logistics of postharvest handling of fruits. As the trend has been changing, people are moving away from synthetic treatment agents; thus, these have been replaced with eco-friendly products. Since the last few years, introduction of some environmental and consumer friendly approaches like brassinosteroids, methyl jasmonates, oxalic acid, salicylic acid, edible coatings, biocontrol agents, irradiation, and cold plasma techniques has made this line more interesting across the globe. These agents work effectively and better over traditional synthetic chemicals. Application of these formulations has been found to be better to retain the quality and fresh like appearance during storage of fruits during supply chain and storage. Thus, there is urgent need to develop some novel technologies for better establishment of fruit growing industries and their maximum retention of quality. The use of these in an integrated manner could be a better way to minimize this huge loss and maximize the quality.

“…4). Brassinosteroids are the most important naturally occurring plant growth-promoting steroidal hormones which not only play a pivotal role in inducing the disease resistance or plant innate immunity but also regulates several growth and development processes like photo-morphogenesis, hormonal regulation, dwarfism, seed germination, change in the distribution pattern of stomata, flowering, senescence, pollen tube elongation, male sterility, xylem differentiation and root growth, confer tolerance/resistance to a broad range of biotic and abiotic stresses (thermal, salinity, oxidative, heavy metal stresses) in several plant species (Krishna, 2003;Kagale et al, 2007;Bajguzand Hayat, 2009;Divi and Krishna, 2010;Coll, et al, 2015).We observed that number of brassinosteroids synthesis genes in healthy (HB-1) and malformed buds (MB-1) were similar. In malformed tissues, the biosynthesis genes increased as the stage of malformation proceeds from MB-1 to MB-3; whereas in healthy tissues, from bud to panicle development stage, it remained unchanged.…”
