Xavier Argout and colleagues report the draft genome of Theobroma cacao, tropical crop that is source chocolate. The sequence assembly covers approximately 80% genome. We sequenced assembled an economically important tropical-fruit tree This corresponds to 76% estimated size contains almost all previously described genes, with 82% these genes anchored on 10 T. cacao chromosomes. Analysis this information highlighted specific expansion some gene families during evolution, for example,...

Gossypium, the cotton genus, includes ∼50 species distributed in tropical and sub-tropical regions of all continents except Europe. Here we provide a synopsis evolutionary history Gossypium domestication American allopolyploid species, integrating data from fundamental taxonomic investigations, biogeography, molecular genetics, phylogenetic analysis, archaeology. These diverse sources information temporal perspective on diversification among diploids polyploid formation, uncover multiple...

Snow Petrels vary greatly in size, the largest birds being over twice as heavy smallest. Two morphological types have been distinguished, but Adelieland population alone shows continuous variation spanning complete range of species. There is no evidence size‐related assortative mating. Size cannot be attributed to nest site location nor individual age, large sexual dimorphism sufficient account for situation. The great size accompanied by an important genetic variability revealed a starch...

Textile use of the cotton fibres from Old World species Gossypium arboreum (Tree Cotton) and G. herbaceum (Levant started around eight thousand years ago possibly earlier. During third millennium before present, cultivation, textile trading developed strongly in many places Indian Subcontinent Near East, but involved are often undetermined. difficult to distinguish morphologically when dealing with archaeological remains.

Plants" natural defense mechanisms against herbivorous arthropods include the emission of volatile organic compounds (VOC).Nowadays field observations about plant-insect interactions are better understood thanks to increasingly scientific investigations over recent decades.There now more precise data molecules, action modes and physiological genetic bases these plant mechanisms.VOC present an important potential for crop protection pesticide use reduction.In review, we focus on latest...

Three Gossypium species have been used to breed cotton as they vary in their fiber production and resistance stresses. Transcription factors (TFs) mostly are present different copies or isoforms by which conduct regulation. Their copy number can determine organism behavior a cue.

Cotton is a resilient and multipurpose crop, meeting major of the world’s textile needs while also yielding byproducts like edible oil animal feed. Starch plays crucial role in cotton fabric production. It enhances strength by forming protective film around fibers, making them more resistant to wear tear.

The history of cotton ( Gossypium sp), which has been a plant major economic interest for some time, relies on the dried or charred seeds found in archaeobotanical assemblages. Our capacity to document dispersal routes cotton, however, is hampered by lack taxonomic resolution at specific levels based current seed anatomic features. In order explore signal interspecific level seeds, and impact carbonization this signal, we used 2D geometric morphometrics (GM) comparing modern fresh four...
