Functional Analysis of the miR156 Regulatory Network in Arabidopsis Siliques
… miR156/SPL2 pathway controls the development of floral organs, regulates pollen production, and thus affects male fertility in Arabidopsis thaliana. I present evidence that SPL2 binds to the 5’UTR of the ASYMMETRIC LEAVES 2 (AS2) gene in vivo, indicating that AS2 acts downstream of SPL2. When …

Characterization of 16B09 and 2D01 effector proteins in cyst nematodes
… repeat receptor kinase that controls floral organ abscission and lateral root emergence, and is expressed in the nematode feeding cell, was identified as a potential host target of this effector.

The role of the transcription factor JAGGED in early floral organogenesis
Initiation of organ primordia from pools of undifferentiated cells requires coordinated cytoplasmic growth, oriented cell wall extension, and cell cycle progression. It is debated which of these processes are primary drivers for organ morphogenesis and directly targeted by developmental regulators. …

Poly(A) Polymerase 1 (PAPS1) influences organ size and pathogen response in Arabidopsis thaliana
… mutant in PAPS1 leads to increase in floral organ size, whereas leaf size is reduced. A strong loss-of-function mutation causes a male gametophytic defect, whereas a weak allele leads to reduced leaf growth. By contrast, plants lacking both PAPS2 and PAPS4 function are viable with …

The Evolution and Development of Nectar Spurs
Nectar spurs (tubular outgrowths of a floral organ which contain or give the appearance of containing nectar) are hypothesized to be a ‘key innovation’ which can lead to rapid speciation within a lineage, because they are involved in pollinator specificity. However, given that there are no …

Female sterility and carpel development in plants
… diversity in shape, size, color, structure and organization of their reproductive organs contained within the flowers. With regard to the sexual nature of the flowers, males, females and hermaphrodites occur in nature, with hermaphroditism being the norm. About 6% of flowering plants are …

Recent advances using genetic analyses in waterhemp
… due to enrichment of terms associated with floral initiation and floral organ development. Hybridization studies and gene-flow experiments were conducted between A. tuberculatus and its close phylogenetic neighbor, A. arenicola. Under directed crosses, hybridization fecundity was comparable …

Identification and functional characterization of microRNA regulatory elements in Brassicaceae
… TAS3, and consequently regulate lateral organ and later root development in plants. In order to understand the regulatory mechanism of microRNAs in an evolutionary term, microRNA390a and microRNA390b in Arabidopsis were chosen and studied. In 16 phylogenetically related species within …
