A new species. Quinisulcius solani, is described and illustrated from specimens on Solanum tuberosum from Murree Hills, Pakistan. Q. solani n.sp. differs from its closest relative, Q. acutus (Allen, 1955) Siddiqi, 1971, by its spiral to open 'C' shaped body and stylet length of 19 mun, vs. 17 mum in Q. acutus. In Q. acutus the stylet knobs project anteriorly but slope posteriorly in Q. solani n...

In contrast to the slow rate of depolymerization of pure actin in vitro, populations of actin filaments in vivo turn over rapidly. Therefore, the rate of actin depolymerization must be accelerated by one or more factors in the cell. Since the actin dynamics in Listeria monocytogenes tails bear many similarities to those in the lamellipodia of moving cells, we have used Listeria as a model syste...

Some muscle-bone relationships were studied in terms of gastrocnemius muscle weight, femur and tibia length and femur and tibia weight in four lines of mice (CBi-, CBi+, CBi/L and CBi/C) artificially selected for different body conformations and in the unselected control line (CBi). CBi- (low body weight--short tail) and CBi+ (high body weight--long tail) lines were divergently selected followi...

Similar to eukaryotic mRNA, the positive-strand coronavirus genome of ~30 kilobases is 5'-capped and 3'-polyadenylated. It has been demonstrated that the length of the coronaviral poly(A) tail is not static but regulated during infection; however, little is known regarding the factors involved in coronaviral polyadenylation and its regulation. Here, we show that during infection, the level of c...

The transition of primary alcohol molecules from bulk water to the surface is driven by entropy, increasing linearly with length hydrophobic tail. enthalpy adsorption nearly invariant molecule.

Six new species of Fergusobia, from large multilocular shoot bud galls on two species of Angophora and four species of Eucalyptus from both subgenera Eucalyptus and Symphyomyrtus, are described. Fergusobia cosmophyllae Davies n. sp. is characterized by the combination of a C-shaped parthenogenetic female with a short arcuate conoid tail, a broad (small a ratio) arcuate infective female with an ...

AlaSTRACT.--Sexual wing dimorphism in relation to tail ornaments and body size was studied in the strikingly sexually dimorphic widowbirds and bishops (Euplectes) of the African tropics. Seven widowbirds grow long tails, varying from 7 cm in Fan-tailed Widowbird (E. axillaris) to 0.5 m in the Long-tailed Widowbird (E. progne). Aerodynamic drag increases with tail length, and adaptations to comp...

A nematode collected from Diaprepes abbreviatus is identified and described as a new species, Steinernema diaprepesi n. sp. The new species is closely related to S. feltiae, S. glaseri, and S. oregonense and can be distinguished from these species by the following characteristics: Males: Spicule averaging 79 (71-90) microm and spicule shape; D% (distance from anterior end to excretory pore/ eso...

The complexity of organismal function challenges our ability to understand the evolution of animal locomotion. To meet this challenge, we used a combination of biomechanics, phylogenetic comparative analyses, and theoretical morphology to examine evolutionary changes in body shape and how those changes affected swimming performance in ascidian larvae. Results of phylogenetic comparative analyse...

The present investigation was undertaken to study the physical and morphometric characteristics in indigenous cattle of Assam. The data pertain to 339 indigenous cattle of different categories. The physical characteristics included colour pattern of body coat, muzzle, tail switch, hoof and horn. Body length, height at wither, heart girth, pouch girth, length of tail, switch, neck, ear and head ...
