Physiological factors influencing climate-smart agriculture: Daylength-mediated interaction between tillering and flowering in rice.

ABSTRACT:

Background

Controlling rice tillering and flowering is essential for reducing greenhouse gas emissions from paddy fields, a key objective in climate-smart agriculture. However, the interaction between tillering and flowering remains controversial and poorly understood. In this study, we subjected plants of the rice cultivars 'Saenuri' and 'Odae' to short- and long-day conditions and compared their growth and flowering responses after tiller removal.

Results

The effects of tiller removal differed depending on daylength conditions. Under short days, plants in the tiller-removal group flowered earlier than the controls, whereas the opposite trend was observed under long days. This response was associated with changes in florigen gene expression. Under short days, the expression
