Area of Science:

Agricultural Science
Plant Biotechnology
Hydroponics

Background:

High protein yields are crucial for cost-effective plant-made pharmaceuticals (PMPs) in transgenic rice.
Silicon (Si) is essential for rice, but its supplementation in hydroponics is challenging due to pH and nutrient instability.
Existing Si sources can disrupt hydroponic system stability, hindering efficient PMP production.

Purpose of the Study:

To develop a stable and practical method for silicon (Si) supplementation in hydroponic rice cultivation.
To evaluate the impact of a novel silica-hydrogel fertilizer (SiHF) on rice growth, yield, and protein productivity.
To optimize SiHF application for enhanced PMP production in controlled rice environments.

Main Methods:

A passive Si supplementation strategy using silica-hydrogel fertilizer (SiHF) submerged in nutrient reservoirs was developed.
Hydroponically grown rice was treated with varying concentrations of SiHF to assess its effects.
Plant growth, biomass, yield, phenology, water uptake efficiency, and protein productivity were quantified.

Main Results:

SiHF significantly increased shoot biomass and grain yield, with optimal results at 500 g/10 L.
Water uptake efficiency per unit root mass increased, leading to greater shoot biomass allocation, despite reduced root weight.
Total protein yield per plant increased by 1.98-fold, with no significant changes in protein composition, and advanced heading stage by up to 4 days.

Conclusions:

The SiHF method provides a stable and effective way to supplement silicon in hydroponic rice systems.
This approach optimizes biomass allocation and enhances total protein yield, crucial for PMP production.
SiHF application accelerates reproductive transition and offers a practical foundation for efficient rice-based plant factory systems.
