Transition of somatic plant cells to an embryogenic state
Under appropriate in vivo or in vitro conditions, certain somatic plant cells have the
capability to initiate embryogenic development (somatic embryogenesis). Somatic …

Multiple pathways in the decision to flower: enabling, promoting, and resetting
At a certain point in their life cycle, annual plants undergo a major developmental transition
and switch from vegetative to reproductive development. This process is rarely reversible …

MINISEED3 (MINI3), a WRKY family gene, and HAIKU2 (IKU2), a leucine-rich repeat (LRR) KINASE gene, are regulators of seed size in Arabidopsis
We have identified mutant alleles of two sporophytically acting genes, HAIKU2 (IKU2) and
MINISEED3 (MINI3). Homozygotes of these alleles produce a small seed phenotype …

MicroRNAs prevent precocious gene expression and enable pattern formation during plant embryogenesis
Arabidopsis embryos lacking DICER-LIKE1 (DCL1), which is required for microRNA
(miRNA) biogenesis, arrest early in development. To assess the functions of embryonic …

Engineering apomixis: clonal seeds approaching the fields
CJ Underwood, R Mercier - Annual review of plant biology, 2022 - annualreviews.org
Apomixis is a form of reproduction leading to clonal seeds and offspring that are genetically
identical to the maternal plant. While apomixis naturally occurs in hundreds of plant species …

Apomixis: a developmental perspective
AM Koltunow, U Grossniklaus - Annual review of plant biology, 2003 - annualreviews.org
