Gibberellin and Jasmonate Crosstalk during Stamen Development [PDF]

Journal of Integrative Plant Biology, 2009
Abstract Gibberellin (GA) and jasmonate (JA) are two types of phytohormones that play important roles during stamen development. For example, Arabidopsis plants deficient in either of GA or JA develop short stamens. An apparent question to ask is whether GA action and JA action during stamen filament development are independent of each other or are in ...

Non-autonomy of AGAMOUS function in flower development: use of a Cre/loxP method for mosaic analysis in Arabidopsis [PDF]

, 1998
Angiosperms use a multi-layered meristem (typically L1, L2 and L3) to produce primordia that then develop into plant organs, A number of experiments show that communication between the cell layers is important for normal development.

Petrocodon gracilis (Gesneriaceae) is a synonym of P. mirus based on morphological and molecular data

Nordic Journal of Botany, EarlyView.
Petrocodon gracilis T.Ding & B.Pan and P. mirus X.Z.Shi, J.X.Fu & Li H.Yang are two recently described species exhibiting nearly identical morphology. To determine whether they represent the same taxon, we compared their type localities, type materials, and morphological features and conducted phylogenetic analyses using the nuclear internal ...

Typification and rediscovery of Phialacanthus griffithii Benth. & Hook.f. (Acanthaceae) in Arunachal Pradesh, India

Nordic Journal of Botany, EarlyView.
Phialacanthus griffithii Benth. & Hook.f. (Acanthaceae), a species long thought unrecorded, was rediscovered in 2023 after a 160‐year gap in the Upper Dibang Valley, Eastern Himalaya, Arunachal Pradesh. The study presents a comprehensive taxonomic account including lectotypification, morphological description, phenology, habitat ecology, distribution ...

Genome-Wide DNA Methylation Profiling in the Lotus (Nelumbo nucifera) Flower Showing its Contribution to the Stamen Petaloid

Plants, 2019
DNA methylation is a vital epigenetic modification. Methylation has a significant effect on the gene expression influencing the regulation of different physiological processes. Current studies on DNA methylation have been conducted on model plants. Lotus

First Measurements of Mixed Floral Traits Influencing <i>Anacardium occidentale</i> (Anacardeacae) Attractiveness to Bees in Côte d'Ivoire: Conservation and Agricultural Implications. [PDF]

Ecol Evol
This paper will contribute to include/use the bees' floral preference (floral traits related to bee' visitations) to find and validate genetic markers that would enable breeding high‐yielding cashew plants and preserving pollinators. ABSTRACT In Sub‐Saharan Africa, cashew plants face challenges in suitable pollination and good agronomic performances ...

Unraveling cryptic lineages in Jatropha nana: phylogenetic evidence supports species status for J. benghalensis (Euphorbiaceae)

Nordic Journal of Botany, EarlyView.
The taxonomic framework of the genus Jatropha (Euphorbiaceae) is well established, but its geophytic species present significant classification challenges. These difficulties arise from species complexes, cryptic traits, and high environmental and phenotypic variability.

A taxonomic update of the genus Clavija (Theophrastaceae) in Colombia and Ecuador

Nordic Journal of Botany, EarlyView.
Two species of Clavija are described as new to science: C. neivea (Department Huila Colombia), which is similar to C. pungens (Willd. ex Roem. & Schult.) Decne. of coastal Ecuador, but distinguished by its chiefly elliptic leaf blades with less serrate margins and 4‐merous flowers; C. zamorae (Prov.

Taxonomic treatment, geographic distribution and preliminar conservation status of Croton sect. Barhamia subsect. Barhamia (Euphorbiaceae) in Brazil

Nordic Journal of Botany, EarlyView.
The genus Croton (Euphorbiaceae) is an exceptionally megadiverse genus, encompassing roughly 1200 species that are predominantly distributed across tropical regions globally. For the New World, the genus is organized into three subgenera (Adenophylli, Geiseleria and Quadrilobi) and 31 sections, with C. sect. Barhamia standing out with its approximately

Comparison of X-ray and gamma-ray dose-response curves for pink somatic mutations in Tradescantia clone 02 [PDF]

, 1976
Microdosimetric data indicate that the mean specific energy,zeta, produced by individual charged particles from X rays and gamma rays is different for the two radiation qualities by nearly a factor of two.
