Translation initiation in plants: roles and implications beyond protein synthesis

Biologia Plantarum, 2015
Protein synthesis is a ubiquitous and essential process in all organisms, including plants. It is primarily regulated at translation initiation stage which is mediated through a number of translation initiation factors (eIFs).

[Light and electron microscopic studies on the sporogenesis of Sphaerospora molnari in the gill lamellas of carp (Cyprinus carpio)]

, 1995
The sporogenesis of Sphaerospora molnari in the gill lamellas of the common carp was investigated by light- and electron microscopy. Whereas pseudoplasmodia were not identified, the development from one secondary cell containing two tertiary cells to the

An ultrastructural and histopathological study of Henneguya pellucida n. sp. (Myxosporea: Myxobolidae) infecting Piaractus mesopotamicus (Characidae) cultivated in Brazil

Parasite, 2005
During a study of myxosporean parasites of cultivated freshwater fish, a new myxosporean species, Henneguya pellucida n. sp., was discovered. Of the 120 Piaractus mesopotamicus sampled, only 10 specimens (8.3%) were infected.

Sporogenesis in Polypodiaceae (Filicales). III. Species of several genera. Spore characters and their value in phylogenetic analysis

, 1993
Mature spores were studied in more than 30 species from sixteen genera of Polypodiaceae. Of ten of these species sporogenesis was also studied, after the application of conventional fixation techniques for transmission electron microscopy, or of freeze ...

Detection of the initial infective stages of the protozoan parasite Marteilia sydneyi in Saccostrea glomerata and their development through to sporogenesis

, 2002
DNA probes were used in in situ hybridisation on histological sections of oysters exposed for defined intervals to Marteilia sydneyi infection to reveal the early development of the parasite in the oyster host, Saccostrea glomerata. The initial infective

The transcription factors and pathways underpinning male reproductive development in Arabidopsis

Frontiers in Plant Science
As Arabidopsis flowers mature, specialized cells within the anthers undergo meiosis, leading to the production of haploid microspores that differentiate into mature pollen grains, each containing two sperm cells for double fertilization.
