Manipulating brassinosteroid signaling pathway to genetically improve horticultural plants

Area of Science:

• Plant Biology
• Hormone Signaling
• Agricultural Science

Background:

• Brassinosteroids (BRs) are essential plant-specific steroidal hormones.
• Previous reviews primarily focused on BRs in model plants and major food crops.
• Horticultural plants, vital for agriculture, have received less attention regarding BR functions.

Purpose of the Study:

• To review the significant roles of Brassinosteroids (BRs) in horticultural plants.
• To focus on BRs' impact on fruit and leaf development, plant architecture, and stress adaptation.
• To identify challenges and future research directions for improving horticultural plants via BR signaling.

Main Methods:

• Literature review of Brassinosteroid (BR) research.
• Synthesis of findings on BRs in horticultural plant physiology.
• Analysis of current challenges and future prospects in BR research for horticulture.

Main Results:

• Brassinosteroids (BRs) significantly influence horticultural plant development, including fruit and leaf growth.
• BRs play a key role in shaping whole plant architecture in horticultural species.
• BR signaling is critical for horticultural plants' adaptive responses to environmental stresses.

Conclusions:

• Brassinosteroids (BRs) are crucial for horticultural plant productivity and resilience.
• Further research into BR signaling pathways can guide genetic improvement of horticultural crops.
• Understanding BRs offers potential for enhancing fruit yield, quality, and stress tolerance in horticulture.
