Does Altering Local Water Availability for an Invasive Plant (Raphanus raphanistrum) Affect Floral Morphology and Reproductive Potential?

American Journal of Undergraduate Research, 2015
Abiotic environmental variation can have dramatic effects on plant floral morphology and nectar or pollen rewards. In response, pollinators may change their foraging behavior and distribution and if pollinators change their foraging behavior or distribution, this could have dramatic effects on the reproductive success of plant populations.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Evaluation of breeding material on the basis of morphological and cytological characteristics of the reproductive organs of plants of the genus Miscanthus

Plant varieties studying and protection, 2023
Purpose. To study in vitro the morphological and cytological characteristics of anthers, pollen and pistils of plants of the genus Miscanthus. Methods. Preparations of pistils, unpollinated seed buds, anthers and pollen, unstained or stained with a solution of carmine (2%) in acetic acid (45%) or methylene blue solution, were examined by light ...

GmMYB181, a Soybean R2R3-MYB Protein, Increases Branch Number in Transgenic Arabidopsis

Frontiers in Plant Science, 2018
Soybean (Glycine max) is an important economic crop that provides abundant oil and high quality protein for human beings. As the process of reproductive growth directly determines the crop seed yield and quality, we initiated studies to identify genes ...

Reproductive biology of "Helianthemum apennium" (L.) Mill. and "H. caput-felis" Boiss. (Cistaceae) from Mallorca (Balearic Island, Spain) [PDF]

, 1997
El estudio de la biología reproductiva de poblaciones naturales de Helianthemum apenninum y H. caput-felis en Mallorca ha demostrado que son básicamente entomófilos, aunque también producen numerosos frutos por auto-polinización. Las flores de H.

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]

, 2017
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
