WE report the discovery of new hormones, termed brassins, in rape pollen (Brassica napus L.). Following the general practice of designating gibberellins as plant hormones, we speak of brassins as hormones because they are specific translocatable organic compounds isolated from a plant and have induced measurable growth control when applied in minute amounts to another plant. 
The chemical characteristic and distribution of brassinosteroids in plants.
Brassinosteroids - : new class of plant hormone with potential to improve crop productivity
TLDR
The article reviews the studies employing brassinosteroids on crop plants such as vegetables, fruits, cereals, oil seeds and others and highlights the constraints faced earlier in large scale field application and also presents the current scenario enlisting the commercially available brass inosteroids.
Effects of brassinolide on the growing of rice plants.
TLDR
Since weak non-steroidal brassinolide-like compound (NSBR1) also induced spiral formation, this root spiral induction can be used as the index in the search for BL-like compounds.
Brassinosteroids
TLDR
Brassinosteroids are steroid hormones ubiquitously found in plants but first purified from Brassica, and have potential applications ranging from improving plant stress tolerances to increasing grain yields.
Enhancement of overall plant growth, a new response to brassins.
TLDR
Using the fatty hormones, brassins, the authors increased repeatedly the overall growth of bean and some other kinds of plants in greenhouse conditions during the past 3 yr, which has broad implications for the existence of hormone control factors of a new type.
The Influence of Brassinosteroid, a Growth-promoting Steroidal Lactone, on Development and CO2-fixation Capacity of Intact Wheat and Mustard Seedlings
TLDR
In 1970, Mitchell et al. isolated a lipoidal complex from the pollen of rape, called “Brassins”, which was found to have partly powerful growth-promoting properties.
Q&A: what are brassinosteroids and how do they act in plants?
Brassinosteroids (BRs) are a class of polyhydroxylated steroidal phytohormones in plants with similar structures to animals’ steroid hormones. Brassinosteroids regulate a wide range of physiological
Brassinosteroid Mutants of Crops

TLDR
Mutants in the biosynthesis, metabolism, and signaling of brassinolide (BL), the most bioactive BR, are important resources in helping to establish BRs’ essential role in plant growth and development.

TLDR
The lipid effect in plants and the juvenile hormone response in insects have much in common and the evidence suggests they could have a similar locus of action in a membrane controlling respiratory function.
