Changes in inflorescence protein during advanced stages of floret development in Buchloe dactyloides (Poaceae)

Y. - J. Zhou, Xue, J. - G., Wang, X. - G., and Zhang, X. - Q., “Changes in inflorescence protein during advanced stages of floret development in Buchloe dactyloides (Poaceae)”, vol. 11, pp. 3923-3932, 2012.

Buffalograss, Buchloe dactyloides, is a dioecious species native to the Great Plains of North America. The florets at the early stages of development possess both gynoecium and androecium organ primordia but later become unisexual. Very little is known about the proteomic changes that occur when the florets change from hermaphroditism to unisexuality. We compared the protein composition of florets at the hermaphroditic stage with that at the unisexual stage. The development stage of the floret was determined by stereomicroscopic observation.

Comparative proteomic analysis between early developmental stages of the Coffea arabica fruits

Coffee is one of the most valuable agricultural commodities. There is much agronomic research on coffee, but molecular knowledge of its fruit development and ripening is limited. This study reports a comparative proteomic investigation of immature coffee fruits in two early developmental stages: stage 1, cell division and elongation of the perisperm; and stage 2, early growth of the endosperm progressively replacing the perisperm.

Preferred amino acids and thermostability

S. T. Farias and Bonato, M. Christina, “Preferred amino acids and thermostability”, vol. 2, pp. 383-393, 2003.

Most organisms grow at temperatures from 20 to 50°C, but some prokaryotes, including Archaea and Bacteria, are capable of withstanding higher temperatures, from 60 to >100°C. Their biomolecules, especially proteins, must be sufficiently stable to function under these extreme conditions; however, the basis for thermostability remains elusive.
