Genetic control of branching is a primary determinant of yield, regulating seed number and harvesting ability, yet little is known about the molecular networks that shape grain-bearing inflorescences of cereal crops. Here, we used the maize (Zea mays) inflorescence to investigate gene networks that modulate determinacy, specifically the decision to allow branch growth. We characterized developm...
Drought is among the most serious abiotic stresses in many parts of the world where cereal crops are essential human food source. Breeding cereals for such stress tolerance is strongly challenging the breeders’ efforts where difficulties are compounded by the complexity of crop yield on the genetic and physiological bases. For cereal plants, drought tends to develop slowly under field condition...
Roots are important to plants for a wide variety of processes, including nutrient and water uptake, anchoring and mechanical support, storage functions, and as the major interface between the plant and various biotic and abiotic factors in the soil environment. Understanding the development and architecture of roots holds potential for the exploitation and manipulation of root characteristics t...
Transcription of the vernalization1 gene (VRN1) is induced by prolonged cold (vernalization) to trigger flowering of cereal crops, such as wheat and barley. VRN1 encodes a MADS box transcription factor that promotes flowering by regulating the expression of other genes. Here we use transcriptome sequencing (RNA-seq) and chromatin immunoprecipitation sequencing (ChIP-seq) to identify direct targ...
Cereal crops such as wheat, rice and barley underpin the staple diet for human consumption globally. A multitude of threats to stable and secure yields of these crops exist including from losses caused by pathogens, particularly fungal. Plants have evolved complex mechanisms to resist pathogens including programmed cell death responses, the release of pathogenicity-related proteins and oxidativ...
the bird cherry-oat aphid, rhopalosiphum padi (l.) is a serious threat to several cereal crops. host-plant resistance to this aphid could be especially valuable in cereal crops pest management. therefore, we evaluated the development, survivorship, reproduction and population growth parameters of r. padi as resistance indices among six wheat cultivars, including gaskojen, tajan, falat, saysonz,...
• Canola is one of the most profitable crops available to grain growers in southern and western Australia and rotations have been adapted to accommodate it. • Canola provides large yield benefits to subsequent cereal crops by providing an effective disease break. • Canola was often grown as the first crop after pasture but now canola is often used more intensively in rotations, posing problems ...
Rotation with dicotyledonous crops to break cereal monoculture has proven to be beneficial to successive cereals. In two fields where the soil had been subjected to prolonged, continuous cereal production, two 3-year rotation trials were established. In the first year, faba bean, turnip rape and barley were grown, as first crops, in large blocks and their residues tilled into the soil after har...
