In botany, a glume is a bract (leaf-like structure) below a spikelet in the inflorescence (flower cluster) of grasses (Poaceae) or the flowers of sedges (Cyperaceae). There are two other types of bracts in the spikelets of grasses: the lemma and palea.

Feb 1, 2019 · Here, we found that over expression of Q in common wheat leads to homeotic florets at glume positions. We provide phenotypic, microscopy, and marker genes evidence to demonstrate that the soft glumes of common wheat are …

Mar 19, 2021 · Red glumes are frequent among Central European spelt, a dominant wheat subspecies in Europe before the 20 th century. We used genotyping-by-sequencing to characterize a global diversity panel of...

Sep 6, 2021 · In wheat, the grain-producing florets form within spikelets, which are composed of three to four florets subtended by a modified leaf-like structure called a glume (Figure 1).

May 7, 2009 · In hexaploid wheat, the glume tenacity gene Tg along with the major domestication locus Q control threshability. The Q gene was isolated recently and found to be a member of the AP2 class of transcription factors. However, only a few studies have reported on …

Wheat glume, which is the main green tissue of spikes, facilitates photosynthesis and delays aging under drought conditions . To clarify the effects of the major hormones in the wheat glume in response to drought stress, we compared the available data for 629 DEGs under water deficit conditions at 6 days after anthesis [ 28 ] with the data ...

May 30, 2024 · Glume pubescence is an important morphological trait for the characterization of wheat cultivars. It shows tolerance to biotic and abiotic stresses to some extent. Hg1 (formerly named Hg) locus on chromosome 1AS controls glume pubescence in wheat.

Oct 13, 2015 · Our main goal was to explore changes in transcriptome expression in glumes that accompanied wheat evolution under domestication. A total of six tetraploid wheat accessions were selected for transcriptome profiling based on their rachis brittleness and glumes toughness.

Jan 12, 2024 · In wheat, pubescence is visible on leaves, leaf sheath, glumes and nodes. Regarding glumes, the presence of pubescence plays a pivotal role in its classification. It supplements other spike characteristics, aiding in distinguishing between different varieties within the wheat species.

Two non-leaf green organs in wheat, glume and awn, have photosynthetic potential, contribute to grain yield, and also play roles in resistance to adverse conditions. We performed the first integrated proteome analysis of wheat glume and awn in response to water deficit.
