Phytohormone-Mediated Plant Architecture Regulation

Plant architecture is a key factor determining crop yield, mechanical harvesting efficiency, and stress tolerance. Traditional breeding primarily relies on screening natural variation and empirical selection, which are time-consuming and inefficient and make it difficult to achieve precise, coordinated optimization of multiple traits. With advancements in phytohormone biology, synthetic biology, and gene editing technologies, phenotype-directed design based on hormone regulatory networks offers a reliable solution for regulating plant architecture. Lifeasible specializes in plant architecture modification. Leveraging our expertise in phytohormone molecular biology, we provide one-stop hormone regulation solutions ranging from phenotypic design to molecular improvement, helping clients overcome bottlenecks in crop breeding.

Branching architecture engineering

Plant branching (or tillering) is a key factor influencing crop yield structure and spatial utilization efficiency. Its formation is regulated by the synergistic action of multiple hormones, primarily auxin, cytokinin, and strigolactones. These three hormones determine the number and spatial distribution of branches.

We offer hormone-regulated strategies for directed branching modification, primarily including branching-enhancing designs and branching-inhibiting designs.

Branching-enhancing design (suitable for high-yield crops such as rice and wheat)	Reduce the efficiency of auxin polar transport (by regulating PIN proteins). Increase cytokinin synthesis (by regulating IPT genes). Inhibit strigolactone synthesis or signaling (by targeting the SL pathway).
Branch suppression design (suitable for horticultural plants)	Enhance auxin dominance. Increase gibberellin signal response. Reduce cytokinin levels.

Plant height optimization

Plant height directly affects a crop's resistance to lodging and planting density, making it a core trait in modern high-yield agricultural systems. In plant height optimization, we primarily achieve our goals by regulating gibberellins (GA), brassinosteroids (BR), and auxins.

Our solutions mainly include dwarfing designs for plant architecture modification, as well as height-increasing or biomass-enhancing designs.

Semi-dwarf engineering (suitable for high-density planting of food crops)	Inhibit GA biosynthesis (regulate GA20ox/GA3ox). Enhance the stability of DELLA proteins (negative regulators of the GA signaling pathway). Precisely regulate GA receptor expression.
Plant height and biomass enhancement design (suitable for biomass energy crops or forage)	Enhance the GA signaling pathway. Improve BR synthesis and response capacity. Synergistically optimize genes related to cell elongation.

Our Technology Platforms

Gene editing platform	The plant gene-editing technology platform we have established enables modification of hormone levels or signaling pathways by knocking out, knocking in, or base-editing key genes, thereby creating new plant architectures.
Synthetic biology platform	We have established an advanced synthetic biology technology platform to enable more precise, controllable regulation. Additionally, by designing tissue- or developmental stage-specific promoters, we drive the expression of hormone metabolism or signaling genes in specific locations, achieving localized optimization of plant architecture.
RNA Interference Technology Platform	We utilize RNAi to silence specific genes, continuously altering endogenous hormone balance to regulate plant architecture. For example, overexpression of cytokinin synthesis genes promotes branching.
Multi-omics analysis platform	Our multi-omics analysis platform supports integrated transcriptomic and metabolomic analysis, as well as phenotype-hormone association modeling.
