The Arabidopsis homeotic genes APETALA3 and PISTILLATA are sufficient to provide the B class organ identity function [PDF]
, 1996 The class B organ identity genes, APETALA3 and PISTILLATA, are required to specify petal and stamen identity in the Arabidopsis flower. We show here that the activities of these two genes are sufficient to specify petals and stamens in flowers, in ...

Sedum zhenghaianum (Crassulaceae), a new species from Zhejiang and Jiangxi, East China
Nordic Journal of Botany, EarlyView.In this paper, Sedum zhenghaianum sp. nov. is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. Morphological analysis indicates that S. zhenghaianum should be classified in the genus Sedum sect. Sedum and is distinct from the related species S. tosaense in morphology, e.g.

A regulatory network for coordinated flower maturation. [PDF]
PLoS Genetics, 2012 For self-pollinating plants to reproduce, male and female organ development must be coordinated as flowers mature. The Arabidopsis transcription factors AUXIN RESPONSE FACTOR 6 (ARF6) and ARF8 regulate this complex process by promoting petal expansion ...

Psychotria caraballoensis (Rubiaceae), a new species from northern Luzon, Philippines
Nordic Journal of Botany, EarlyView.In this paper, we describe and illustrate Psychotria caraballoensis, a new endemic species from the Caraballo Mountain Range, Luzon, Philippines. It is allied to the Subalpina species group sensu Sohmer and Davis (2007), and resembles Psychotria sohotonensis.

Sensitive Stamens in Portulaca
The American Naturalist, 1873 Two years ago my attention was first called to the sensitiveness of the stamens of Portulaca grandiflora, by observing a peculiar motion in them, while a small wild bee was engaged in gathering honey, and perhaps pollen, from the flowers. Upon trial I found that I could, by touching the stamens, make them move through quite considerable arcs of circles.

The CLAVATA and SHOOT MERISTEMLESS loci competitively regulate meristem activity in Arabidopsis [PDF]
, 1996 The CLAVATA (CLV1 and CLV3) and SHOOT MERISTEMLESS (STM) genes specifically regulate shoot meristem development in Arabidopsis. CLV and STH appear to have opposite functions: c1v1 and Clv3 mutants accumulate excess undifferentiated cells in the shoot and
