Genetic control of seed shattering in rice by the APETALA2 transcription factor shattering abortion1.
Seed shattering is an important agricultural trait in crop domestication. SH4 (for grain shattering quantitative trait locus on chromosome 4) and qSH1 (for quantitative trait locus of seed shattering on chromosome 1) genes have been identified as required for reduced seed shattering during rice (Oryza sativa) domestication. However, the regulatory pathways of seed shattering in rice remain unkn...
متن کاملControl of seed mass by APETALA2.
Arabidopsis APETALA2 (AP2) encodes a member of the AP2/EREBP (ethylene responsive element binding protein) class of transcription factors and is involved in the specification of floral organ identity, establishment of floral meristem identity, suppression of floral meristem indeterminancy, and development of the ovule and seed coat. Here, we show that loss-of-function ap2 mutations cause an inc...
متن کاملOrchestration of the floral transition and floral development in Arabidopsis by the bifunctional transcription factor APETALA2.
The Arabidopsis thaliana transcription factor APETALA2 (AP2) has numerous functions, including roles in seed development, stem cell maintenance, and specification of floral organ identity. To understand the relationship between these different roles, we mapped direct targets of AP2 on a genome-wide scale in two tissue types. We find that AP2 binds to thousands of loci in the developing flower, ...
متن کاملThe Arabidopsis MYB5 transcription factor regulates mucilage synthesis, seed coat development, and trichome morphogenesis.
The Arabidopsis thaliana MYB5 gene is expressed in trichomes and seeds, including the seed coat. Constitutive expression of MYB5 resulted in the formation of more small trichomes and ectopic trichomes and a reduction in total leaf trichome numbers and branching. A myb5 mutant displayed minimal changes in trichome morphology, while a myb23 mutant produced increased numbers of small trichomes and...
متن کاملTranscription factor Lmo4 defines the shape of functional areas in developing cortices and regulates sensorimotor control.
Proper formation of the shape and size of cortical functional areas is essential for complex brain function, including sensory perception and motor control. Our previous work identified the transcription factor Lim domain only 4 (Lmo4), a regulator in calcium-dependent gene transcription, that has unique, region-specific expression in postnatal mouse cortices with high expression anteriorly and...
