A Developmental Basis for Stochasticity in Floral Organ Numbers [PDF]
Frontiers in Plant Science, 2014 Stochasticity ubiquitously inevitably appears at all levels from molecular traits to multicellular, morphological traits. Intrinsic stochasticity in biochemical reactions underlies the typical intercellular distributions of chemical concentrations, e.g.,

Interactions between FLORAL ORGAN NUMBER₄ and floral homeotic genes in regulating rice flower development [PDF]
Journal of Experimental Botany, 2017 The floral meristem (FM) is self-maintaining at the early stages of flower development, but it is terminated when a fixed number of floral organs are produced. The FLORAL ORGAN NUMBER4 (FON4; also known as FON2) gene, an ortholog of Arabidopsis CLAVATA3 (

FON2 SPARE1 redundantly regulates floral meristem maintenance with FLORAL ORGAN NUMBER2 in rice. [PDF]
PLoS Genetics, 2009 CLAVATA signaling restricts stem cell identity in the shoot apical meristem (SAM) in Arabidopsis thaliana. In rice (Oryza sativa), FLORAL ORGAN NUMBER2 (FON2), closely related to CLV3, is involved as a signaling molecule in a similar pathway to ...

AGAMOUS mediates timing of guard cell formation during gynoecium development.
PLoS Genetics, 2023 In Arabidopsis thaliana, stomata are composed of two guard cells that control the aperture of a central pore to facilitate gas exchange between the plant and its environment, which is particularly important during photosynthesis.

Specification of floral organs in Arabidopsis [PDF]
Journal of Experimental Botany, 2013 Floral organs are specified by the activities of a small group of transcriptional regulators, the floral organ identity factors. Extensive genetic and molecular analyses have shown that these proteins act as master regulators of flower development, and function not only in organ identity determination but also during organ morphogenesis. Although it is

Linking Hsp90 function to micro-environmental and stochastic variation in floralorgans of Iris pumila L. [PDF]
Archives of Biological Sciences, 2008 Hsp90 is an environmentally responsive molecular chaperone that was found to play a key role in buffering against genetic and non-genetic perturbations in the model organisms Arabidopsis and Drosophila.

Histone acetylation accompanied with promoter sequences displaying differential expression profiles of B-class MADS-box genes for phalaenopsis floral morphogenesis. [PDF]
PLoS ONE, 2014 Five B-class MADS-box genes, including four APETALA3 (AP3)-like PeMADS2∼5 and one PISTILLATA (PI)-like PeMADS6, specify the spectacular flower morphology in orchids. The PI-like PeMADS6 ubiquitously expresses in all floral organs. The four AP3-like genes,

The Origin of Floral Organ Identity Quartets [PDF]
The Plant Cell, 2017 The origin of flowers has puzzled plant biologists ever since Darwin referred to their sudden appearance in the fossil record as an abominable mystery. Flowers are considered to be an assembly of protective, attractive, and reproductive male and female leaf-like organs.

In planta localisation patterns of MADS domain proteins during floral development in Arabidopsis thaliana [PDF]
, 2009 Background: MADS domain transcription factors play important roles in various developmental processes in flowering plants. Members of this family play a prominent role in the transition to flowering and the specification of floral organ identity. Several
