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 ...

The role of salicylic acid in plant flower development

open access: yesForestry Research, 2022
Salicylic acid (SA), belonging to a family of naturally occurring phenolic compounds, is a crucial plant hormone involved in many biological processes, such as plant immunity, seed germination, root initiation, stomatal closure, and biotic/abiotic stress

Drawing Planar Graphs with a Prescribed Inner Face [PDF]

open access: yes, 2013
Given a plane graph $G$ (i.e., a planar graph with a fixed planar embedding) and a simple cycle $C$ in $G$ whose vertices are mapped to a convex polygon, we consider the question whether this drawing can be extended to a planar straight-line drawing of ...

Gibberellin acts through jasmonate to control the expression of MYB21, MYB24, and MYB57 to promote stamen filament growth in Arabidopsis. [PDF]

open access: yesPLoS Genetics, 2009
Precise coordination between stamen and pistil development is essential to make a fertile flower. Mutations impairing stamen filament elongation, pollen maturation, or anther dehiscence will cause male sterility.

Heat Stress Leads to Poor Fruiting Mainly Due to Inferior Pollen Viability and Reduces Shoot Photosystem II Efficiency in “Da Hong” Pitaya

open access: yesAgronomy, 2022
High summer temperatures (day/night: 40 °C/30 °C) are known to cause poor fruiting, reduced fruit/seed weight, and delayed fruit development in the “Da Hong” red-fleshed pitaya (Hylocereus polyrhizus); however, the mechanisms of these effects are unknown.

Characterization of the Ubiquitin C-Terminal Hydrolase and Ubiquitin-Specific Protease Families in Rice (Oryza sativa)

open access: yesFrontiers in Plant Science, 2018
The ubiquitin C-terminal hydrolase (UCH) and ubiquitin-specific processing protease (UBP) protein families both function in protein deubiquitination, playing important roles in a wide range of biological processes in animals, fungi, and plants. Little is

Cytological characterization and allelism testing of anther developmental mutants identified in a screen of maize male sterile lines. [PDF]

open access: yes, 2013
Proper regulation of anther differentiation is crucial for producing functional pollen, and defects in or absence of any anther cell type result in male sterility.

Morphological and anatomical features of the flowers and fruits during the development of Chamissoa altissima (Jacq.) Kunth (Amaranthaceae)

open access: yesBrazilian Archives of Biology and Technology, 2010
The morphology and structure of the flowers and fruits of Chamissoa altissima (Jacq.) Kunth during the development were analyzed. The plant material was fixed in FAA 50, embedded in historesin and sectioned according to standard techniques.
