Defective kernel 66 encodes a GTPase essential for kernel development in maize

DEK66 encodes a mitochondrial ribosomal assembly factor and is involved in the regulation of maize kernel development by affecting the morphology and function o

`by assessing granule numbers during grain development in the phs1 mutant..we demonstrate that PHS1 is exclusively involved in B-type granule initiation. The total #starch content & # of starch granules per #chloroplast in leaves were not affected by loss of PHS1, suggesting that its role in granule initiation..is limited to the #endosperm..initiation of A- & B-type granules occurs via distinct..mechanisms..PHS1 plays an exclusive role in B-type granule initiation`

Initiation of B-type starch granules in wheat endosperm requires the plastidial α-glucan phosphorylase PHS1

The α-glucan phosphorylase PHS1, together with its glucan-binding protein interaction partner, BGC1, are required for normal numbers and size of B-type granules

🌱 #Endosperm is a nutritive tissue important to support developing seedlings
🌱 Sometimes it can develop independently of fertilisation (autonomously) in both sexual and #apomictic plants

#Amylose content determines taste, texture, look, and digestibility of #rice, and is controlled by alleles of the #Waxy gene. This study explores how kinase OsSK41/OsGSK5 negatively regulates AC in rice #endosperm.
