The Galeommatoidea is a bivalve superfamily that exhibits high species diversity in shallow waters. Many members of this superfamily are associated commensally with burrowing marine invertebrates in benthic sediments. The genus Borniopsis is known only from eastern Asia and exhibits high host diversity (e.g., mantis shrimps, crabs, holothurians, sipunculans and echiurans). A new species, Bornio...

The ciliary ganglion is a well-defined ovate ganglionic mass in the three species studied Uromastyx aegyptius, Sphenops sepsoides and Varanus griseus. The ganglion consists of bipolar neurons in the three species studied. In both Uromastyx and Sphenops the neurons are of two sizes large and small, while in Varanus they are of one and the same size. In the three species studied, the ciliary gang...

Background/Purpose: Congenital duodenal obstruction is a frequent cause of intestinal obstruction in the newborn. The incomplete nature of the obstruction in duodenal stenosis results in a variable and often delayed presentation. It usually results in recurrent episodes of vomiting, aspiration, or failure to thrive. Some patients present in adulthood with gastroesophageal reflux, peptic ulcerat...

Three new species of the streptaxid snail genus Perrottetia are described from north and northeastern Thailand, Perrottetia aquilonaria sp. n., Perrottetia dermapyrrhosa sp. n. and Perrottetia phuphamanensis sp. n. Each species is endemic to a single or a few limestone mountain ranges. The species are characterized by the morphology of their genital organs, as well as by shell characters. Perro...

Abstract The variability of metric traits has been studied in 20 Kazakhstan populations three Nitraria species ( N. schoberi L., sibirica Pall., and komarovii Iljin & Lava ex Bobrov). According to the results, differs from small leaves, fruits, seeds, as well structural features inflorescences flowers. is characterized by a greater number flowers per inflorescence (25–66 on average) than (1...

Up to the late 1990s and early 2000s, several small-leaved species of Chenopodium (Amaranthaceae s. lato/Chenopodiaceae stricto) were frequently misnamed in floras central Asia Siberia. Two widespread taxa, C. prostratum (now accepted as karoi) vulvaria, commonly recognized. However, latter is absent from Siberia occurs only southwestern Asia. Further north name ‘vulvaria’ was misapplied two sp...

GOLD, R. E., and K. MENDGEN. 1984. Cytology of basidiospore germination, penetration, and early colonization of Phaseolus vulgaris by Uromyces appendiculatus var. appendiculatus. Can. J. Bot. 62: 1989-2002. Cytological studies were done on a compatible interaction between Phaseolu.\ vulgaris and Uromyces appendiculatus var. appendiculatus. The cytoplasm of germinated basidiospores contained num...

Tomato flower abscises at the anatomically distinct abscission zone that separates the pedicel into basal and apical portions. During abscission, cell separation occurs only at the abscission zone indicating distinctive molecular regulation in its cells. We conducted a transcriptome analysis of tomato pedicel tissues during ethylene promoted abscission. We found that the abscission zone was the...

This article conta ined descriptions of five new taxa of Mexican Euphorbiaceae. Euphorbia (sub g. Agaloma) na yarensis is endemic to pine-oak woodland in the mount ains of central Nayarit. It appears related to E. so ob yi but differs by possessing linear to linear-ovate leaves. Croton varelae is also endemic to central Nayarit. A key was provided to distinguish this spec ies. a member of sect....

Abstract Fleshy fruit shape is an important external quality trait influencing the usage of fruits and consumer preference. Thus, modification becomes one major objectives for crop improvement. However, underlying mechanisms regulation are poorly understood. In this review, we summarize recent progresses in genetic basis fleshy using tomato, cucumber peach as examples. Comparative analyses sugg...
