Pseudomonas aeruginosa causes many biofilm infections, and the rugose small-colony variants (RSCVs) of this bacterium are important for infection. We found here that inactivation of PA2444, which we determined to be a serine hydroxymethyltransferase (SHMT), leads to the RSCV phenotype of P. aeruginosa PA14. In addition, loss of PA2444 increases biofilm formation by two orders of magnitude, incr...

Neurobeachin (Nbea) is implicated in vesicle trafficking in the regulatory secretory pathway, but details on its molecular function are currently unknown. We have used Drosophila melanogaster mutants for rugose (rg), the Drosophila homolog of Nbea, to further elucidate the function of this multidomain protein. Rg is expressed in a granular pattern reminiscent of the Golgi network in neuronal ce...

We sequenced seven cpDNA regions from 70 spp. in Dodecatheon, Primula subgenus Auriculastrum, and outgroups, reconstructed their cpDNA phylogeny with maximum parsimony, and determined branch support with bootstrap frequencies and Bayesian posterior probabilities. Strongly supported conclusions include the (1) paraphyly of Primula subgenus Auriculastrum with respect to a monophyletic Dodecatheon...

Rugose spiraling whitefly, Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae) is an invasive pest causing severe damage to several plant species. Surveys were conducted in the farmers’ orchards of 11 coastal districts Bangladesh namely Patuakhali, Barguna, Barishal, Khulna, Bagherhat, Pirojpur, Jhalokathi, Bhola, Laxmipur, Noakhali and Cox’s Bazar know host range rugose whitefly its in...

Pseudomonas aeruginosa is known to show considerable variation in colony form and physiological properties, including pigment production. Gaby (1946) has recently reported biochemical and other observations on certain "basic colony types." Mucoid variants of P. aeruginosa have been described by Sonnenschein (1927) and by Schwarz and Lazarus (1947); Fiala (1941) has described the appearance of "...

Synommatus leleji sp. n. is described and illustrated from the Philippines (Mindanao Island). The new species differs other of genus in suboval elytra with rounded sides, rugose-punctate pronotum, rostrum subequal to pronotum length. A key distribution map for are given. It first record Philippines.
