Resequencing of 1,143 indica rice accessions reveals important genetic variations and different heterosis patterns

Nature Communications, 2020
Hybrid rice cultivars are widely planted around the world. Here, the authors resequence 1,143 indica accessions, focusing on the parents of superior hybrid rice lines in China, and reveal genetic loci that are associated with heterosis via measuring ...

Profit‐maximizing potassium fertilizer recommendations for corn and cotton

Agronomy Journal, Volume 114, Issue 6, Page 3358-3376, November/December 2022., 2022
Abstract Whereas K fertilization is necessary to maximize corn (Zea mays L.) and cotton (Gossypium hirsutum L.) yields in soils with sub‐optimum K availability, maximizing yield is rarely profit‐maximizing. Estimating the tradeoff between yield and fertilizer cost using current soil‐building and/or yield‐maximizing rate recommendations vs.

Fine mapping of GS2, a dominant gene for big grain rice

Crop Journal, 2013
Grain shape as a major determinant of rice yield and quality is widely believed to be controlled by quantitative trait loci (QTL). We have identified a novel gene “GS2” to largely regulate grain length and width in rice.

Absence of mixed valency for Pr in pristine and hole-doped PrNiO$_2$ [PDF]

Phys. Rev. B 107, 165153 (2023), 2023
Infinite-layer nickelates ($R$NiO$_2$) exhibit some distinct differences as compared to cuprate superconductors, leading to a debate concerning the role of rare-earth ions ($R$=La, Pr, Nd) in the low-energy many-body physics. Although rare-earth $4f$ orbitals are typically treated as inert `core' electrons in studies, this approximation has been ...

OsLAP6/OsPKS1, an orthologue of Arabidopsis PKSA/LAP6, is critical for proper pollen exine formation

Rice, 2017
Background Male fertility is crucial for rice yield, and the improvement of rice yield requires hybrid production that depends on male sterile lines.

A method for mechanized hybrid rice seed production using female sterile rice

Rice, 2019
Background The breeding and large-scale adoption of hybrid rice is an important achievement in modern agriculture. Mechanized seed production is urgently needed for widespread adoption of hybrid rice because it can compensate for the shortage of manual ...

Responses of the Lodging Resistance of Indica Rice Cultivars to Temperature and Solar Radiation under Field Conditions

Agronomy, 2022
Much attention has shifted to the effects of temperature and solar radiation on rice production and grain quality due to global climate change. Meanwhile, lodging is a major cause of rice yield and quality losses.

Identification of a New Wide-Compatibility Locus in Inter-Subspecific Hybrids of Rice (Oryza sativa L.)

Agronomy, 2022
As a special class of rice germplasm, wide-compatibility varieties (WCVs) guarantee the fertility of hybrids when there is cross-fertilization between two subspecies.

Ferromagnetism of magnetic semiconductors--Zhang-Rice limit [PDF]

Phys. Rev. B 66, 033203 (2002), 2001
It is suggested that p-d hybridization contributes significantly to the hole binding energy E_b of Mn acceptors in III-V compounds, leading in an extreme case to the formation of Zhang-Rice-like small magnetic polarons. The model explains both strong increase of E_b and evolution of Mn spin-resonance spectrum with the magnitude of valence-band offsets.
