An awn is a hairy or bristle-like growth on a plant. On the seeds of grasses such as barley or rye, they form foxtails which assist seed dispersal by being barbed and so sticking to passing animals.

Awns have potential impacts on plant performance through their known functions during grain development, such as carbon accumulation and remobilization, and improved water-use efficiency [5, 6, 7].

2024年12月1日 · Awns are, most frequently, distal bristle-like extensions of lemmas — outer protective organs of grass flowers (Figure 1 a). Although not always adaptive, awns can have diverse roles, including in herbivore protection, diaspore dispersal, seed germination, and seed maturation [4, ∗∗5, ∗∗6].

2024年11月18日 · Replicated trait evolution can provide insights into the mechanisms underlying the evolution of biodiversity. One example of replicated evolution is the awn, an organ elaboration in grass infloresce...

The identification of biological mechanisms underlying the development of complex quantitative traits, including those that contribute to plant architecture, yield and quality potential, and seed dispersal, is a major focus in the evolutionary biology and plant breeding. The awn, a bristle-like extension from the lemma in the floret, is one of ...

2023年8月4日 · Awns are bristle-like extensions of the glumes and/or husks of many grass species including the major crop plants such as wheat, rice, barley, and rye. The awns provide protection against pests and foraging animals. They are considered important due to their physiological role in photosynthesis [1].

2021年7月14日 · 近日，中国农业大学林中伟教授课题组在Molecular plant上发表了题为“Gene duplication drove the loss of awn in sorghum”的研究论文。 该研究论文发现了 awn1 基因的复制导致高粱在驯化和改良过程芒丢失的进化遗传机制。

2021年6月29日 · In this study, using chromosome segment substitution lines (CSSLs) derived from a long-awned Guangxi common wild rice (GXCWR, Oryza rufipogon Griff.) and a short-awned indica cultivar 9311, we identified An-4, a potential …

The USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which perennial plants are most likely to thrive at a location. The map is based on the average annual extreme minimum winter temperature, displayed as 10-degree F zones and 5-degree F half zones. A broadband internet connection is recommended for the ...

The first marker loci available had an obvious impact on the morphology of plants. Genes that affect form, coloration, male sterility, or resistance (among others) have been analyzed in many plant species. Examples of this type of marker include the presence or absence of awn, leaf sheath coloration, height, grain color, aroma (rice), etc. In ...
