The clockwork of plant circadian oscillators has been resolved through investigations in Arabidopsis thaliana. The circadian oscillator is an important regulator of much of plant physiology, though many of the mechanisms are unclear. New findings ...

Arabidopsis plants store part of the carbon fixed by photosynthesis as starch to sustain growth at night. Two competing hypotheses have been proposed to explain this diel starch turnover based on either the measurement of starch abundance with res...

This study assessed the effects of gonadotropin-releasing hormone (GnRH) treatment on Day 5 (Day 0 = estrus) on luteal blood flow and accuracy of pregnancy prediction in recipient cows. On Day 5, 120 lactating Holstein cows were randomly assigned ...

This study aimed to assess the suitability of luteal blood flow analyses measured by color Doppler ultrasonography (CDUS) to predict pregnancy at pre- and post-embryo transfer (ET) in dairy cows and to compare with the established criterion like l...

• We model the evolution of indirect reciprocity, using reputation spreading process.
• We examine the effects of false information intentionally started by some players.
• More and more gossip sessions are favored when no players start false info...

• This study quantified effects of florigen distribution on inflorescence architecture.
• We developed the phloem transportation model for florigen.
• The model predicted diverse inflorescence architectures observed in Arabidopsis.
• The model hig...
Rice (Oryza sativa) is one of the most important food crops in the world. Numerous quantitative trait loci or genes controlling panicle architecture have been identified to increase grain yield. Yet grain yield, defined as the product of th...

According to the viewpoint of the optimal strategy theory, a tree is expected to shed its leaves when they no longer contribute to maximisation of net carbon gain. Several theoretical models have been proposed in which a tree was assumed to strate...

Cultural transmission between individuals can take various forms. One-to-many transmission refers to the case when each individual in a population socially acquires cultural traits from one particular individual who occupies a special social statu...

It is valuable to set an ideotype plant structure (i.e., ideal numbers and arrangement of sucrose sources, sinks, and pathways that maximize crop yield) as a goal for breeding with modern and near-future technologies. However, it is not easy to th...

A repeated game is a formal model for analyzing cooperation in long-term relationships. The case where each player observes her opponent's action with some observation errors (imperfect private monitoring) is difficult to analyze, and existing wor...
