Timing is everything: early degradation of abscission layer is associated with increased seed shattering in U.S. weedy rice

BMC Plant Biology, 2011
Background Seed shattering, or shedding, is an important fitness trait for wild and weedy grasses. U.S. weedy rice (Oryza sativa) is a highly shattering weed, thought to have evolved from non-shattering cultivated ancestors. All U.S.

A 48-bp deletion upstream of LIGULELESS 1 alters rice panicle architecture

Crop Journal
Panicle architecture is an agronomic determinant of crop yield and a target for cereal crop improvement. To investigate its molecular mechanisms in rice, we performed map-based cloning and characterization of OPEN PANICLE 1 (OP1), a gain-of-function ...

Bulliform Phytolith Research in Wild and Domesticated Rice Paddy Soil in South China.

PLoS ONE, 2015
Bulliform phytoliths play an important role in researching rice origins as they can be used to distinguish between wild and domesticated rice. Rice bulliform phytoliths are characterized by numerous small shallow fish-scale decorations on the lateral ...

ERK‐Mediated Phosphorylation of YAP Defines a Noncanonical FGF Signaling Mechanism in Stem Cells

Advanced Science, EarlyView.
With a powerful combination of in vivo, ex vivo, and in vitro models, the authors highlight a novel FGF‐ERK signaling regulation of YAP at the S128 site in neural crest‐derived stem cells. This study opens exciting new directions in stem cell biology and craniofacial biology, paving the way for potential innovations in the treatment of craniofacial ...

A Rare Allele of ST5 From Wild Rice Enhances Salt Tolerance in Rice

Advanced Science, EarlyView.
A novel salt‐tolerance gene ST5W, characterized by a unique 36‐bp promoter insertion, is found exclusively in a small subset of Oryza rufipogon and is absent in cultivated rice. Field trials confirm ST5W significantly enhances rice yield across diverse genetic backgrounds under saline conditions.

Australian wild rice reveals pre-domestication origin of polymorphism deserts in rice genome. [PDF]

PLoS ONE, 2014
BACKGROUND:Rice is a major source of human food with a predominantly Asian production base. Domestication involved selection of traits that are desirable for agriculture and to human consumers.

Hijacking the Host Clock: A Nematode Effector Antagonizes Soybean Circadian Defense and Translation Control

Advanced Science, EarlyView.
Soybean employs its circadian clock, governed by GmCCA1, to rhythmically defend against soybean cyst nematodes. The pathogen retaliates by secreting the effector Hg4E02, which hijacks the clock to suppress defense and co‐opt the host's translation machinery for nutrient acquisition.

QTL Mapping for Plant Height Using Introgression Lines Derived from Zhonghui 8015 and Wild Rice (Oryza rufipogon)

Rice Science, 2022
Many excellent genes in wild rice have been lost during the domestication of wild rice to cultivated rice. In this study, introgression lines (ILs) were produced with a wild rice (Oryza rufipogon) accession, BJ194, as a donor parent and an indica ...

3D Chromatin Architecture Provides Insights Into Leaf Trait Variation Among Pear Species

Advanced Science, EarlyView.
ABSTRACT Three‐dimensional (3D) chromatin architecture plays a fundamental role in eukaryotic gene regulations, its functional significance in perennial fruit trees remains poorly characterized despite extensive applications in crop genomics. Here, we developed high‐resolution (∼5 kb) Hi‐C maps of Pyrus and compared 3D genomic architecture of three ...

Comparative study of the mycorrhizal root transcriptomes of wild and cultivated rice in response to the pathogen Magnaporthe oryzae

Rice, 2019
Background Rice, which serves as a staple food for more than half of the world’s population, is very susceptible to the pathogenic fungus, Magnaporthe oryzae. However, common wild rice (Oryza rufipogon), which is the ancestor of Asian cultivated rice (O.
