Programmed Cell Death and Postharvest Deterioration of Horticultural Produce [PDF]

open access: yes, 2010
Programmed cell death (PCD) is a process where cells or tissues are broken down in an orderly and predictable manner, whereby nutrients are re-used by other cells, tissues or plant parts.

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 ...

Molecular Cloning and Expression Profile of Class E Genes Related to Sepal Development in Nelumbo nucifera

open access: yesPlants, 2021
The lotus (Nelumbo Adans.) is an important aquatic plant with ornamental, medicinal and edible values and cultural connotations. It has single-, semi-double-, double- and thousand-petalled types of flower shape and is an ideal material for developmental ...

Do Epigenetic Timers Control Petal Development?

open access: yesFrontiers in Plant Science, 2021
Epigenetic modifications include histone modifications and DNA methylation; such modifications can induce heritable changes in gene expression by altering DNA accessibility and chromatin structure.

Transcriptome Analysis Reveals Putative Target Genes of APETALA3-3 During Early Floral Development in Nigella damascena L.

open access: yesFrontiers in Plant Science, 2021
Even though petals are homoplastic structures, their identity consistently involves genes of the APETALA3 (AP3) lineage. However, the extent to which the networks downstream of AP3 are conserved in species with petals of different evolutionary origins is

Unraveling the Regulatory Mechanism of Color Diversity in Camellia japonica Petals by Integrative Transcriptome and Metabolome Analysis

open access: yesFrontiers in Plant Science, 2021
Camellia japonica petals are colorful, rich in anthocyanins, and possess important ornamental, edible, and medicinal value. However, the regulatory mechanism of anthocyanin accumulation in C. japonica is still unclear.

On Reconfiguring Tree Linkages: Trees can Lock [PDF]

open access: yes, 2000
It has recently been shown that any simple (i.e. nonintersecting) polygonal chain in the plane can be reconfigured to lie on a straight line, and any simple polygon can be reconfigured to be convex.

Micro- and Macroscale Patterns of Petal Morphogenesis in Nigella damascena (Ranunculaceae) Revealed by Geometric Morphometrics and Cellular Analyses

open access: yesFrontiers in Plant Science, 2021
Petals, the inner organs in a differentiated perianth, generally play an important role in pollinator attraction. As such they exhibit an extraordinary diversity of shapes, sizes, and colors.

Comprehensive transcriptome analyses of different Crocus flower tissues uncover genes involved in crocin biosynthesis

open access: yesBiologia Plantarum, 2020
The stigma of Crocus sativus is used in traditional Chinese medicine and has drawn attention as a rich source of crocin, a compound with a reported activity that counters various cancers, depression, and cardiovascular diseases. However, our knowledge of
