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.…

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…

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…

Qin et al. identify a mechanism by which ethylene activates gibberellin catabolism to determine primary root growth in rice. Hua Qin and Rongfeng Huang Biotechnology Research Institute, Chinese Academy of Agricultural Sciences Background: The optimization of root architecture is one of the…

In addition to its role as a nutrient and a developmental signal, nitrate regulates stress responses in plants. By homology to nitrate transporters previously identified in Arabidopsis as contributing to stress induced-nitrate allocation to roots (SINAR) and nitrogen use efficiency (NUE), Guan et al.…

Groen et al. investigate the genes and traits under selection when rice experiences drought.  By Simon C. “Niels” Groen a,b and Amelia Henryc a Institute of Integrative Genome Biology and Department of Nematology, University of California at Riverside, Riverside, CA, USA; b Center for Genomics…

Rice grain is mainly composed of starch, which provides the necessary energy and sugars for successful germination and seedling development. Since rice is the most widely consumed crop, studying the regulators that control starch synthesis is crucial to ensure food security for more than half the world‘s…

Wang and colleagues investigated the starvation response of rice seedlings. By Wentao Wang and Yue Lu Background: For survival and growth, cells of all living organisms must balance their energy consumption and supply. Although energetically autonomous (through photosynthesis), plants are continuously…
