Reviews how rice root and shoot traits govern carbon acquisition, allocation, and soil retention under contrasting water regimes. Proposes four operational archetypes (deep explorer, source maximizer, sink maximizer, balanced integrator) as selection criteria for breeding and management. Field validation with multimodal phenotyping, yield, carbon budgets, and GHG balances is required.

日本のGX文脈において
農業由来の炭素・GHG管理はScope 3やサプライチェーン排出に直結するが、本稿は育種・農学寄りで日本の開示実務への直接的示唆は限定的。水田の炭素動態に関心を持つ読者には参考になる。
In the global GX context
Adds to the growing literature linking crop trait selection to agricultural carbon and GHG accounting, relevant to Scope 3 agricultural emissions and nature-based mitigation, though it remains at the hypothesis stage without disclosure or policy implications.

📄 Abstract（原文）
Rice (Oryza sativa L.) provides a primary source of caloric intake for over half of the global population. Aligning grain production with climate mitigation requires understanding how plant traits influence carbon balance under contrasting water regimes, which affect both trait expression and the fate of plant-derived carbon in soil and greenhouse-gas emissions. Here, the morphological and physiological attributes that govern carbon acquisition, allocation, and retention in rice were reviewed. Belowground, root traits contribute through soil exploration, rhizosphere activity, and structural accumulation, influencing resource acquisition, carbon inputs, and gas transport. Aboveground, shoot architecture, stay-green behavior, and source–sink coordination regulates canopy photosynthesis, reserve remobilization, and allocation to grain and residues. These complementary functions across genotypes, developmental stages, and water regimes, distinguishing plant carbon gain from soil retention and the net greenhouse-gas balance, were examined. Four operational archetypes, deep explorer, source maximizer, sink maximizer, and balanced integrator, are proposed as combinations of candidate traits for rice improvement and management. These proposed selection criteria are distinct from previously published observations, and their combined performance requires field validation. Evaluation would consider calibrated multimodal phenotyping with field measurements of yield, carbon allocation, ecosystem carbon budgets, and greenhouse-gas balances. The central hypothesis proposed as a result of this review is as follows: Combining deep root exploration with a coordinated supply of assimilates, the remobilization of reserves, and grain demand could improve carbon retention while maintaining grain yield, with outcomes that depend on the water regime and the fate of the residues.
