Rice seedlings release momilactone B into the environment.
TLDR
The release level of momilactone B and its effectiveness as a growth inhibitor suggest that it may play an important role in rice allelopathy. Expand
Pyruvate metabolism in rice coleoptiles under anaerobiosis
TLDR
The results suggest that the potential carbon flux from pyruvate to ethanol, lactate and alanine in anoxic coleoptiles in rice seedlings subjected to anoxic stress may be much greater than the potential flux from Pyrolysis to lactate, which is currently estimated to be 92, 1 and 7% of the total carbon flux. Expand
Isolation and identification of a potent allelopathic substance in rice root exudates.
TLDR
Results suggest that rice seedlings may release momilactone B into the environment and the stress caused by the husk-treatment may increase the amount of momilACTone B released, which may play an important role in rice allelopathy. Expand
Barnyard grass-induced rice allelopathy and momilactone B.
TLDR
Rice allelopathy may be one of the inducible defense mechanisms by chemical-mediated plant interaction between rice and barnyard grass, and the induced-allelopathy may provide a competitive advantage for rice through suppression of the growth of barn yard grass. Expand
Evaluation of the importance of lactate for the activation of ethanolic fermentation in lettuce roots in anoxia
According to the Davies–Roberts hypothesis, plants primarily respond to oxygen limitation by a burst of lactate production and the resulting pH drop in the cytoplasm activates ethanolic fermentation.Expand
Convergent or parallel molecular evolution of momilactone A and B: potent allelochemicals, momilactones have been found only in rice and the moss Hypnum plumaeforme.

TLDR
Rice and H. plumaeforme plants secrete momilactone A and B into the rhizosphere, and the secretion level was also increased by UV irradiation, elicitor and jasmonic acid treatments, which suggests that both plants, despite their evolutionary distance, may use same defense strategy with respect to the momilactor A andB production and secretion, which resulting from convergent or parallel evolutionary processes.

The catalytic direction of pyrophosphate:fructose 6-phosphate 1-phosphotransferase in rice coleoptiles in anoxia
The catalytic direction of pyrophosphate:fructose-6-phosphate 1-phosphotransferase (PFP; EC 2.7.1.90) in coleoptiles of rice (Oryza sativa L.) seedlings subjected to anoxia stress is discussed. TheExpand
Contribution of momilactone A and B to rice allelopathy.
TLDR
Eight cultivars of rice inhibited shoot and root growth of Echinochloa crus-galli when co-cultured with rice seedlings in a bioassay medium, suggesting that the allelopathic activity of rice may depend primarily on the secretion level of momilactone B. Expand
The Role of Momilactones in Rice Allelopathy
TLDR
Genetic studies have shown that selective removal of the momilactones only from the complex mixture found in rice root exudates significantly reduces allelopathy, demonstrating that these serve as allelochemicals, the importance of which is reflected in the presence of a dedicatedMomilactone biosynthetic gene cluster in the rice genome.
