Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]

open access: yes, 2020
In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.

MADS-box genes controlling inflorescence morphogenesis in sunflower [PDF]

open access: yes, 2008
MADS-box genes play an important role in plant ontogeny, particularly, in the regulation of floral organ induction and development. Eight full-length cDNAs of HAM genes (Helianthus annuus MADS) have been isolated from sunflower.

Biologia da polinização em Lecythidaceae

open access: yesActa Botânica Brasílica, 1987
A família Lecythidaceae apresenta grande diversidade em matas higrófilas localizadas abaixo de 1000 m de altitude. Poucas espécies ocorrem em cerrados, várzeas, e em matas acima de 1000 m.

B-Function Expression in the Flower Center Underlies the Homeotic Phenotype of Lacandonia schismatica (Triuridaceae) [PDF]

open access: yes, 2010
Spontaneous homeotic transformations have been described in natural populations of both plants and animals, but little is known about the molecular-genetic mechanisms underlying these processes in plants.

Non-equilibrium dynamics and floral trait interactions shape extant angiosperm diversity. [PDF]

open access: yes, 2016
Why are some traits and trait combinations exceptionally common across the tree of life, whereas others are vanishingly rare? The distribution of trait diversity across a clade at any time depends on the ancestral state of the clade, the rate at which ...

Local and landscape effects of field margins on aerially dispersing beneficial insects and spiders [PDF]

open access: yes, 2011
Field margins were implemented in UK agri-environment schemes with the aim to increase farmland biodiversity. Recently aerially dispersing aphid enemies have been shown to provide the majority of aphid control in winter wheat fields but there is a lack ...
