Última Differentially displayed expressed sequence tags in Melipona scutellaris (Hymenoptera, Apidae, Meliponini) development Anais da ABC (AABC) Santana,Flávia A.; Nunes,Francis M.F.; Vieira,Carlos U.; Machado,Maria Alice M.S.; Kerr,Warwick E.; Silva Jr,Wilson A.; Bonetti,Ana Maria. We have compared gene expression, using the Differential Display Reverse Transcriptase - Polymerase Chain Reaction (DDRT-PCR) technique, by means of mRNA profile in Melipona scutellaris during ontogenetic postembryonic development, in adult worker, and in both Natural and Juvenile Hormone III-induced adult queen. Six, out of the nine ESTs described here, presented differentially expressed in the phases L1 or L2, or even in both of them, suggesting that key mechanisms to the development of Melipona scutellaris are regulated in these stages. The combination HT11G-AP05 revealed in L1 and L2 a product which matches to thioredoxin reductase protein domain in the Clostridium sporogenes, an important protein during cellular oxidoreduction processes.

Ano: 2006 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0001-37652006000100008 Melipona garbage bees release their cargo according to a Gaussian distribution BJB KERR,A. S.; KERR,W. E.. Worker bees of Melipona compressipes and Melipona scutellaris (Meliponinae, Apidae) colonies, involved in carrying garbage to the outside of the nest, dump each individual load cargo of cocoon pellets (cocoon + larval feces + remaining wax). For Melipona scutellaris they weight a mean of 27.8 mg, and are dropped at a distance of 1 to 45 m and between 1 and 35 m for M. compressipes, according to a Gaussian Distribution. In the case of M. scutellaris the expression is: <img src="http:/img/fbpe/rbbio/v59n1/a15e1.gif"> where, N(x) = number of pellets; Exp = e elevated to the expression in brackets; x = distance in meters; the linear term (bx) describes accidental cargo slipping. The constants for the observed data are: b = 0.69; A = 1363; sigma = 2.16 m;...
