Morphological, Anatomical, Physiological and Genetic Studies of Iris aphylla L. Wild Species Conservation in “Ex Situ” Conditions

Agriculture
Wild Iris plants are usually found in spontaneous flora, but due to their ornamental characteristics, they can also be used for ornamental purposes, which means that it is very important to find the perfect conditions for plant growth.

Scanning Electron Microscope Study of Brachysclereids of Pear (Pyrus communis L.) [PDF]

, 1976
The external surfaces of pear sclereids commonly are illustrated as covered with apertures. This SEAA investigation of the surface features has shown the surface to have few or no apertures.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Potencial de utilização de Cyperus rotundus na descontaminação de áreas de descarte de resíduos industriais com elevados teores de metais Potential to use Cyperus rotundus in areas of industrial waste disposal

Planta Daninha, 2009
A fitorremediação é um processo promissor de descontaminação de solos em que a planta é utilizada como um mecanismo de alocação do agente contaminante e indesejável ao sistema tratado.

Phenotypic landscape inference reveals multiple evolutionary paths to C$_4$ photosynthesis [PDF]

, 2013
C$_4$ photosynthesis has independently evolved from the ancestral C$_3$ pathway in at least 60 plant lineages, but, as with other complex traits, how it evolved is unclear.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Evolution and relationships of the conifer seed cone telemachus: Evidence from the triassic of antarctica [PDF]

, 2010
The seed cone Telemachus is known from several Triassic localities in Gondwana. New specimens from two localities in Antarctica provide additional information about the type species, Telemachus elongatus, based on details of morphology and anatomy ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Adaptive leaf anatomical characteristics of Brachiaria ruziziensis genotypes (Poaceae) in different environments - doi: 10.4025/actascibiolsci.v35i4.18265

Acta Scientiarum: Biological Sciences, 2013
Studies on morphological plasticity are extremely important to plant breeding seeking to optimize genotype interactions with their environments. The present study evaluated 38 genotypes of Brachiaria ruziziensis cultivated during the rainy (October to ...
