“…In this study, BL + Pyr triggered a far more robust transient H 2 O 2 burst than BL or Pyr, indicating a stronger elicitation of the defense mechanism achieved by BL + Pyr. As BL and Pyr alone showed the potential to promote H 2 O 2 accumulation both in this study and previous studies about BL ,− or azoxystrobin (another strobilurin fungicide similar to Pyr) . The more robust transient H 2 O 2 triggered by BL + Pyr might be stemmed from the synergistic interaction between BL and Pyr in triggering H 2 O 2 burst.…”

“…Given that both BL and Pyr independently altered the transcript levels of certain defense genes, which was in line with their regulation on defense gene. 9,11,14 Therefore, the integration of the individual activation effects on defense genes provided by BL and Pyr could partially explain the upregulation of defense genes by BL and Pyr, making it more pronounced and widespread. However, this integration did not fully account for the superior activation on defense genes observed in the BL + Pyr group as a substantial number of defense genes were differentially regulated by BL + Pyr rather than by BL and Pyr alone.…”

“…10 BL also induced plant virus resistance against the cucumber mosaic virus (CMV) through improving antioxidant enzymes activity and defense-associated gene expression. 11 applications of epi-brassinolide (epi-BL) have been found to reduce the disease severity against Colletotrichum gloeosporioides on mango by triggering H 2 O 2 accumulation and activating the antioxidant system and defense response. 12 Pyraclostrobin (Pyr), a strobilurin fungicide, has widespectrum antifungal activity by inhibiting electron transfer in the respiratory electron-transport chain of mitochondria in fungi.…”

Applying brassinolide (BL, a phytohormone) in combination with pyraclostrobin (Pyr, a fungicide) has shown effective disease control in field trials. However, the mechanism by which BL + Pyr control disease remains uncertain. This work compared the disease control and defense responses of three pretreatments (BL, Pyr, and BL + Pyr) in Arabidopsis thaliana. We found that BL + Pyr improved control against Pyr-sensitive Hyaloperonospora arabidopsidis and Botrytis cinerea by 19 and 17% over Pyr, respectively, and achieved 29% control against Pyr-resistant B. cinerea. Furthermore, BL + Pyr outperformed BL or Pyr in boosting transient H 2 O 2 accumulation, and the activities of POD, APX, GST, and GPX. RNA-seq analysis revealed a more potent activation of defense genes elicited by BL + Pyr than by BL or Pyr. Overall, BL + Pyr controlled disease by integrating the elicitation of plant innate disease resistance with the fungicidal activity of Pyr.

“…In another experiment, exogenous application of EBR at optimal concentration was found to be effective for improving resistance against anthracnose caused by Colletotrichum gloeosporioides in mango fruit. The mode of action was by activating defense-related enzymes, increasing total phenols, flavonoids, lignins, and propectin levels, suppressing pectin hydrolases, and controlling Reactive Oxygen Species (ROS) levels and antioxidant enzyme activities in fruits of mango [84]. An experiment conducted by Zaharah [107] revealed that the application of 24-Epibrassinolide (Epi-BL or EBL) resulted in enhanced ripening, fruit softening and colour development, increased ethylene and respiration rate in mango.…”

Brassinosteroids (BRs) are considered as the sixth group of plant growth regulators with significant growth promoting activity in many horticulture and agriculture crops. This phytohormone was discovered from the pollen of Brassica napus L. on the basis of their ability to promote growth. Currently, more than 70 BRs have been isolated from different plant species, but only three viz., Brassinolide (BL), 24-Epibrassinolide (EBL) and 28-Homobrassinolide (HBL) are found to be the most biologically active forms and extensively used in various crops. They are eco-friendly, effective at very low concentration, cost effective and almost always have synergetic effect when interacts with other phytohormones. Owing to diverse physiological roles and cross talk with other hormones influence on plant growth and development, they are being collectively referred as ‘pleiotropic phytohormone’. Although, BRs were discovered towards the end of twentieth century, but the dynamic applications and outcomes were reported mainly during the inception of twenty first century, hence BRs were termed as ‘hormone of the twenty-first century’. The application of BRs at different growth stages have been reported to positively influences such as nutrients uptakes, growth, yield and quality attributes on many fruit crops which includes tropical, sub-tropical and temperate fruit crops at very low concentrations have great roles in terms of growth, yield, fruit quality and stress tolerance mechanisms, which results to lucrative adventure of farming community. This review article will provide an elucidated insight into the application of BR in different fruit crops.
