The KDML105-derived MT2 rice mutant showed genotype-specific grain and proteomic responses to low nitrogen. Nitrogen deficiency reduced some glutelin and allergenic proteins and yielded hydrolysates with stronger in-vitro antibacterial activity, but this is not clinical nutrition evidence.
Key findings
- MT2 had higher carbohydrate and amylose. Under sufficient nitrogen it accumulated functional proteins and produced highly antioxidant hydrolysates; low nitrogen reduced selected glutelin/allergenic proteins and induced MT2-specific proteins correlated with antioxidant and antibacterial assays.
Why this matters globally
If confirmed in fields and foods, low-nitrogen-tolerant varieties and fertilizer management could reduce inputs while creating higher-value ingredients. Yield, seasonal stability and whole-system environmental effects remain essential.
Thai researcher contribution
Mahidol University researchers collaborated with NSTDA and BIOTEC proteomics scientists, combining a Thai rice background with national molecular-biology infrastructure.
Limitations to consider
Controlled nutrient solution is not multi-location farming; protein correlations do not prove mechanism. Hydrolysate assays do not establish digestion, bioavailability, safety or human effects, and proposed low-glutelin or glycemic benefits require testing in cooked food and people.
