Embryo sac development in Stellaria media

Acta Societatis Botanicorum Poloniae, 2014
Osmiophilic granules were observed during certain stages of intermitotic periods in one, two and four nucleate embryo sacs in Stellaria media. The granules, some inside the short ER cisternae, were mainly distributed along the walls of nucleate embryo ...

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Pollen tube growth through nucellus into embryo sac of Spinacia - an ultrastructural investigation

Acta Societatis Botanicorum Poloniae, 2014
The micropylar parts of nucellus and embryo sac were studied in relation to pollen tube growth and its entrance into the embryo sac. The initially homogeneous walls of the cells of the conductive nucellar tissue disintegrate at the middle lamellae region.

Central Cell in Flowering Plants: Specification, Signaling, and Evolution

Frontiers in Plant Science, 2020
During the reproduction of animals and lower plants, one sperm cell usually outcompetes the rivals to fertilize a single egg cell. But in flowering plants, two sperm cells fertilize the two adjacent dimorphic female gametes, the egg and central cell ...

Molecular Editing Reveals a Bilobalide Chemotype that Attenuates Prolyl Endopeptidase (PREP)‐Linked Neuroinflammation

Advanced Science, EarlyView.
Molecular editing of bilobalide uncovers BB56, a PREP‐engaging chemotype with enhanced anti‐inflammatory activity in microglia. Integrated CETSA‐MS, SAR, and pathway analyses link BB56 to attenuation of p38 MAPK/NF‐κB and NLRP3‐associated inflammatory signaling, highlighting bilobalide editing as a strategy for developing neuroinflammation‐modulating ...

Study of some abnormalities of ovule development to seed in Pistacia vera L. [PDF]

Zīst/shināsī-i Giyāhī-i Īrān, 2014
Seed production in some crops like pistachio is limited by some abnormalities in ovule development stages. In this study, the ovule developmental stages as well as abnormalities of these stages were investigated.

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

Advanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Disturbances in the development of the female gametophyte in fully fertile tomatoes (Lycopersicon esculentum L. Mill) and those showing a tendency to parthenocarpy

Acta Societatis Botanicorum Poloniae, 2014
It was found that part of the ovules in two lines of Lycopersicon esculentum: Kholodostoykye (Kh, fertile) and A33 (with a tendency to parthenocarpy) show disturbances in the development of the embryo sac. These irregularities can be seen in four phases:
