Natural variation in the promoter of OsPDX1.2 enhances vitamin B6 accumulation and cold tolerance in rice

Journal of Integrative Plant Biology, EarlyView.
Allelic variation in the promoter of the pyridoxal phosphate synthase OsPDX1.2 caused variation in the ACE‐box cis‐elements, resulting in differing OsPDX1.2 expression due to differences in binding affinity between the OsbZIP18 transcriptipn factor and the ACE‐box, contributing to variation in vitamin B6 levels and cold tolerance among rice varieties ...

Evidence for the Emergence of New Rice Types of Interspecific Hybrid Origin in West African Farmers' Fields

, 2009
In West Africa two rice species (Oryza glaberrima Steud. and Oryza sativa L.) co-exist. Although originally it was thought that interspecific hybridization is impossible without biotechnological methods, progenies of hybridization appear to occur in ...

Heterosis for Root System Development in Japonica/Indica F1 Rice Hybrid.

Japanese Journal of Crop Science, 1993
Vigorous growth of F1 hybrid of rice (Oryza sativa L.) may be partially attributed to the development and function of the root system, but only a few studies have been conducted in this aspect. This study was carried out to elucidate the root system development of heterotic F1 hybrid seedlings grown in culture solution for 30 days.

Fine‐tuning quantitative agronomic traits by manipulating gene copy number in rice

New Phytologist, EarlyView.
Although plant pan‐genome studies have revealed extensive copy number variations, their phenotypic consequences remain poorly understood. Here, we manipulated the copy number of OsMADS18 in rice (Oryza sativa) cv ‘Hitomebore’ using the CRISPR/Cas9 system.

Identification of Wide Compatibility Varieties in Some Tropical Japonica Rice [PDF]

, 2005
The F1 hybrid sterility in indica/japonica crosses is the major barrier in developing hybrid rice varieties between these two diverse germplasm. The sterility problem in japonica/indica hybrids can be overcome by using wide compatibility genes.

Potential phytotoxic and shading effects of invasive Fallopia (Polygonaceae) taxa on the germination of dominant native species [PDF]

, 2011
Two species of the genus Fallopia (F. sachalinensis, F. japonica, Polygonaceae) native to Asia, and their hybrid (F. ×bohemica), belong to the most noxious plant invaders in Europe.

Evaluation of Chinese rice varieties resistant to the root-knot nematode Meloidogyne graminicola

Journal of Integrative Agriculture, 2018
The root-knot nematode Meloidogyne graminicola, which is distributed worldwide, is considered a major constraint on rice production in Asia. The present study used the root gall index and number of nematodes inside the roots to evaluate resistance ...

Key DNA Markers for Predicting Heterosis in F1 Hybrids of japonica Rice

Breeding Science, 2004
Optimizing hybrid vigor (HV) has been a primary objective in hybrid crop breeding programs. The effective use of DNA markers in this endeavor has been plagued by inconsistent results among researchers who investigated the relationship between genetic similarity (GS) among parents and heterosis in their F1’s.
