How the ovules get enclosed in magnoliaceous carpels. [PDF]

open access: yesPLoS ONE, 2017
Angiosperms distinguish themselves from gymnosperms by their ovules that are enclosed before pollination. However, how the ovules get enclosed in angiosperms remains a mystery, especially for Magnoliaceae. The only key to this mystery is finding a series

Influence of Suboptimal Temperature on Flower Quality and Floral Organ Development in Spray-Type Cut Rose ‘Pink Shine’

open access: yesHorticulturae, 2023
Low temperatures commonly delay flowering in cut roses but enhance final flower quality, i.e., biomass, petal doubling, and flower size. However, this information remains unclear for spray-type cut roses. This study was conducted to understand the effect

The Relationship between AGAMOUS and Cytokinin Signaling in the Establishment of Carpeloid Features

open access: yesPlants, 2021
Gynoecium development is dependent on gene regulation and hormonal pathway interactions. The phytohormones auxin and cytokinin are involved in many developmental programs, where cytokinin is normally important for cell division and meristem activity ...

Histone Demethylases ELF6 and JMJ13 Antagonistically Regulate Self-Fertility in Arabidopsis

open access: yesFrontiers in Plant Science, 2021
The chromatin modification H3K27me3 is involved in almost every developmental stage in Arabidopsis. Much remains unknown about the dynamic regulation of this histone modification in flower development and control of self-fertility.

Temporal Distinction between Male and Female Floral Organ Development in Nicotiana tabacum cv. Xanthi (Solanaceae)

open access: yesPlants, 2020
Early floral developmental investigations provide crucial evidence for phylogenetic and molecular studies of plants. The developmental and evolutionary mechanisms underlying the variations in floral organs are critical for a thorough understanding of the

Ring the BELL and tie the KNOX: Roles for TALEs in gynoecium development

open access: yesFrontiers in Plant Science, 2014
Carpels are leaf-like structures that bear ovules, and thus play a crucial role in the plant life cycle. In angiosperms, carpels are the last organs produced by the floral meristem and they differentiate a specialized meristematic tissue from which ...
