2023年10月1日 · In this study, the detachment of the glume (DG) and awn (DA) of a wheat variety (Pubing143) was used to estimate their influences on ear photosynthesis and dry matter distribution. Radioactive carbon-14 (14 C) isotope was detected by a multifunctional liquid scintillation counting system.

2019年1月1日 · 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 …

The glume and awn of ears play prominent roles in wheat grain filling. Awn is more crucial than glume for grain filling, particularly under drought stress. Glume and awn removal causes significant reductions in ear photosynthesis.

2023年10月17日 · In this study, the detachment of the glume (DG) and awn (DA) of a wheat variety (Pubing143) was used to estimate their influences on ear photosynthesis and dry matter distribution. Radioactive carbon-14 (14 C) isotope was detected by a multifunctional liquid scintillation counting system.

2021年11月1日 · The near-isogenic inbred line (NIL) carrying the SV allele (71–73 Mb on chromosome 3) at awn1 showed a long awn on the lemma, whereas the NIL bearing the Tx623 awn1 allele had a fairly short awn on the lemma (Methods; Supplemental Figure 2) that did not outgrow the glume and remained invisible from the outside (Figures 1 B–1E).

2021年11月26日 · In the present study, the “double-awn” wheat 4045, which features super-long lemma awns and long glume awns, and an awnless wheat line, Zhiluowumai, were used to investigate QTLs or genes involved in awn development. QTL analysis identified three loci— Qawn-1D, Qawn-5A, and Qawn-7B —using a population of 101 4045 × ZLWM F 2 plants.

2022年9月1日 · In many grasses, the lemma, one or both glumes, or occasionally the palea, may end in a sharp point, or bear a short, pointed extension (a mucro), or bear a longer extension known as an awn (Figure 1) (Gould and Shaw, 1983; Kellogg, 2000).

2018年8月19日 · Glume awn length, but not glume width, is specifically regulated by the Long glume awn 1 (Lga1) locus on chromosome 7HS, where the dominant allele (Lga1.a) confers long awns and while recessive alleles (lga1.b) lead to short awns.

2023年10月1日 · It is argued that cellular distribution plays a key role in supporting metabolism to enable the various functions undertaken by glume tissue and grain specific regulations in the use of free amino acids in protein synthesis.

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.
