| Elymus and Bromus genera |
have grain width:depth ratios of |
1.43 and 1.76, respectively |
Elymus; Bromus |
| Brachypodium endosperm |
forms |
crescent-shaped structure |
Brachypodium distachyon |
| Brachypodium grain at approximately 8 DAA |
has |
smaller (presumptive) aleurone cells forming around periphery of endosperm |
Brachypodium distachyon |
| small square cells around edge of central endosperm |
appear uniformly distributed |
abaxially, adaxially, and laterally |
Brachypodium distachyon |
| barley grain |
increases in length |
grain length |
Hordeum vulgare |
| grain hardness trait |
is controlled by |
Ha locus |
Triticum turgidum |
| kinetin application at early grain-filling stage |
significantly increases |
grain-filling rate of inferior spikelets in CI regime |
|
| kinetin application in WSD regime |
shows greater increase in |
grain-filling rate and grain weight of inferior spikelets than in CI regime |
|
| developing endosperm |
is where OsSUT1 function is crucial |
|
Oryza sativa |
| presence of the TaAMY3 protein |
was assessed during |
grain development |
Triticum aestivum |
| caryopses spatially located on apical primary branches |
achieve |
larger and heavier grains |
Oryza sativa |
| grain N concentration |
was conserved between |
treatments |
|
| granules initiated before 4 DAA in Aegilops peregrina |
grew continuously until |
maturity |
Aegilops peregrina |
| Golgi apparatus |
were observed only very rarely in starchy endosperm cells from |
16 (DPA, AT5G02470) |
