Oryza glumaepatula: A wild relative to improve drought tolerance in cultivated rice

When we speak about rice, we’re often referring to one of two domesticated species, Oryza japonica or Oryza indica. However, there are an additional 25 species in the genus Oryza. These so-called wild relatives harbor substantial genetic diversity that holds promise for crop improvement. Here, Prakash…

Alternative splicing orchestrates phosphate signaling and plant growth

Guo et al. demonstrate that alternative splicing of REGULATOR OF LEAF INCLINATION 1 modulates phosphate signaling and plant growth in the face of phosphate deficiency.  By Meina Guo, Wenyuan Ruan, and Keke Yi  Background: Phosphate (Pi) limitation represents a primary constraint on crop production.…

Casparian Strip formation at the root endodermis in rice

Wang et al. identify three OsMYB36s that redundantly regulate Casparian strip formation. Jixing Xia; College of Life Science and Technology, Guangxi University, China Background: The Casparian strip (CS) is a ring-like lignin-rich structure in the anticlinal cell wall between endodermal cells…

WHITE-CORE RATE 1 regulates grain chalkiness in rice

Wu et al. uncover a mechanism underlying chalkiness, an important grain quality trait in rice. Background: With improved living standards, the demand for better grain quality has become a challenge in rice production areas. Rice chalkiness, i.e., endosperm containing opaque regions, seriously reduces…
