The infection biology of Fusarium graminearum: Defining the pathways of spikelet to spikelet colonisation in wheat ears [PDF]
Fungal Biology, 2010 Fusarium graminearum is one of the main causal agents of Fusarium Ear Blight on wheat. How the pathogen colonises the entire ear is not known. There is controversy over whether this mycotoxin producing pathogenic fungus invades wheat floral tissue using a necrotrophic or another mode of nutrition.

Identification and Gene Mapping of a multi-floret spikelet 1 (mfs1) Mutant Associated with Spikelet Development in Rice [PDF]
Journal of Integrative Agriculture, 2012 In this study, a rice spikelet mutant, multi-floret spikelet 1 (mfs1), which was derived from ethylmethane sulfonate (EMS)-treated Jinhui 10 (Oryza sativa L. ssp. indica) exhibited pleiotropic defects in spikelet development.

Determination of wheat spike and spikelet architecture and grain traits using X-ray Computed Tomography imaging [PDF]
Plant Methods, 2021 Background Wheat spike architecture is a key determinant of multiple grain yield components and detailed examination of spike morphometric traits is beneficial to explain wheat grain yield and the effects of differing agronomy and genetics.

Jasmonic acid regulates spikelet development in rice [PDF]
Nature Communications, 2014 The spikelet is the basal unit of inflorescence in grasses, and its formation is crucial for reproductive success and cereal yield. Here, we report a previously unknown role of the plant hormone jasmonic acid (JA) in determining rice (Oryza sativa) spikelet morphogenesis.

Genetic and molecular characterization of multiflorous spikelet in oat [PDF]
Genetics and Molecular Research, 2017 Multiflorous spikelets are found in several grass species of agricultural and economic interest. In oat, this morphological characteristic is associated with the production of naked grains. Although many genetic studies have been performed over the past century, the inheritance of the multiflorous spikelet trait is not fully understood in oat.

Effects of Low Temperature Stress on Spikelet-Related Parameters during Anthesis in Indica–Japonica Hybrid Rice [PDF]
Frontiers in Plant Science, 2017 Poor spikelet fertility under low temperature (LT) stress during anthesis limits the possibility of high yield potential in indica–japonica hybrid rice, leading to reduced stability of grain yield. However, the cause for it is still unclear.

High night temperature induces contrasting responses for spikelet fertility, spikelet tissue temperature, flowering characteristics and grain quality in rice [PDF]
, 2023 Climate change is increasing night temperature (NT) more than day temperature (DT) in rice-growing areas. Effects of combinations of NT (24−35°C) from microsporogenesis to anthesis at one or more DT (30 or 35°C) at anthesis on rice spikelet fertility ...
