Field performance and nitrous oxide emissions of transgenic nitrogen use efficient rice lines cultivated in tropical paddy fields.

Nitrogen (N) fertilizers make up the majority of the input used in rice production, and their excess application leads to significant environmental pollution. Developing rice varieties with improved nitrogen use efficiency (NUE) is essential to maintain the sustainability of rice production. This study aims to evaluate the performance of transgenic Oryza sativa japonica cv.

Global epigenetic changes of histone modification under environmental stresses in rice root.

Abiotic stresses are non-living factors with negative morphological and physiological effects on living organisms. Substantial evidence exists that gene expression changes during plant cell growth are regulated by chromatin reconfiguration and histone modification. Several types of histone modifications are dramatically transformed in stress-responsive gene regions under drought stress conditions.
