Mitochondrial AOX1a and an HO feed-forward signalling loop regulate flooding tolerance in rice.

Flooding is a widespread natural disaster that causes tremendous yield losses of global food production. Rice is the only cereal capable of growing in aquatic environments. Direct seeding by which seedlings grow underwater is an important cultivation method for reducing rice production cost.

A newly evolved rice-specific gene JAUP1 regulates jasmonate biosynthesis and signalling to promote root development and multi-stress tolerance.

Root architecture and function are critical for plants to secure water and nutrient supply from the soil, but environmental stresses alter root development. The phytohormone jasmonic acid (JA) regulates plant growth and responses to wounding and other stresses, but its role in root development for adaptation to environmental challenges had not been well investigated. We discovered a novel JA Upregulated Protein 1 gene (JAUP1) that has recently evolved in rice and is specific to modern rice accessions.

Doping effects of CuO additives on the properties of low-temperature-sintered PMnN-PZT-based piezoelectric ceramics and their applications on surface acoustic wave devices.

To develop the anisotropic ceramic substrate with low sintering temperature for surface acoustic wave (SAW) applications, the low cost and feasible material with moderate piezoelectric properties, good dielectric properties, and higher Curie temperature were explored. The piezoelectric ceramics with compositions of Pb[(Mn(1/3)Nb(2/3))(0.06-) (Zr(0.

Transactivation of protein expression by rice HSP101 in planta and using Hsp101 as a selection marker for transformation.

Plant HSP101 has dual activities, first, in conferring thermotolerance, and secondly, in serving as a translational activator. In this study, we introduced Oryza sativa Hsp101 (osHsp101) cDNA into tobacco by Agrobacterium-mediated transformation. Stable integration and expression of the transgene into the tobacco genome was demonstrated by Southern and Western blot analysis.
