Histone H1 and HMG 14/17 are deposited nonrandomly in the nucleus.

We have studied the assembly of histone H1 and the high mobility group nonhistones 14/17 by isopycnic analysis after crosslinking density labeled MSB cell nuclei or chromatin. Carbodiimide crosslinking produces dense poly-H1 and hybrid density H1-H2A histone dimers, indicating that new H1 is deposited nonrandomly, albeit nonconservatively relative to new core histones. Core histone-HMG crosslinking with succinimidyl propionate yields dense HMG 14 in uniformly dense particles and new HMG 17 crosslinked to both dense and light protein, implying that HMG 14 and 17 each deposit nonrandomly; but differently with respect to new core octamers. Propionimidate crosslinking yields dense H1-HMG 17 dimers, suggesting that the interactions of new 14/17 with H1 (new HMG 14-old H1, new HMG 17-new H1) are reciprocal to their interactions with the core histones.     

A new mimetic species of Heliconius (Lepidoptera: Nymphalidae), from southeastern Colombia, revealed by cladistic analysis of mitochondrial DNA sequences

A new species of Heliconius and a new geographical race of Heliconius melpomene are described from the vicinity of Mocoa, Dpto. Putumayo, Colombia, based on molecular and morphological characters. The new species, H. tristero , is a close relative of H. cydno , a geographically differentiated species which lacks red coloration and engages in Müllerian mimicry with other blue and yellow Heliconius species in Central and northwestern South America. H. tristero has switched mimetic associations, instead mimicking the local, sympatric forms of two widespread mimetic species, H. erato and H. melpomene. This discovery provides evidence that the splinter species H. heurippa, H. tristero and H. timareta represent phenotypically divergent members of the H. cydno group that are endemic to successive river valleys on the eastern slope of the northern Andean Cordillera. The nominal taxon Heliconius amaryllis bellula Stichel, currently misapplied to both H. tristero and H. melpomene populations from the Mocoa region of Colombia, is considered here to represent a hybrid between H. heurippa and H. tristero. The Mocoa melpomene race is formally named Heliconius melpomene mocoa , new subspecies.

Novelties in Hedeoma (Labiatae)

Hedeoma pilosum andH. microphyllum are described as new. The former, an endemic of western Texas, is closely related toH. pusillum andH. apiculatum; the latter is intermediate betweenH. costatum andH. nanum. H. oblongifolium var.mexicanum andH. drummondii var.crenulatum are presented as two new varieties, both of which may have originated as hybrids.Hedeoma crenulatum is proposed as a new name to replaceH. montanum (Brade) Epling & Játiva. Three new combinations are made in the genusHesperozygis, and new status is accorded to two species.

Morphological and molecular description of Haematoloechus meridionalis n. sp. (Digenea: Plagiorchioidea: Haematoloechidae) from Rana vaillanti brocchi of Guanacaste, Costa Rica.

An undescribed species of Haematoloechus inhabits the lungs of Rana vaillanti in northwestern Costa Rica. The new species is most similar morphologically to H. medioplexus, having a very small, but well-developed, ventral sucker and lacking extracecal uterine loops, and apparently was mis-identified previously as H. medioplexus in Rana palmipes from Colombia. It differs from H. medioplexus, notably by (1) the shape of the oral sucker, which is elliptical in H. meridionalis and spherical in H. medioplexus; (2) the posterior extent of the vitelline fields, which terminate at the same level in H. medioplexus, but always at different levels in H. meridionalis; (3) the position of the testes, which are immediately posterior to the seminal receptacle and are close together in the new species and far from the seminal receptacle and separated from each other in H. medioplexus; and (4) the location of the genital pore, which is ventral to the cecal bifurcation in the new species and ventral to the pharynx in H. medioplexus. In addition, the new species is unique among members of Haematoloechus by having flaps of tissue on the interior margins of the ventral sucker. The new species shows almost 5% sequence divergence from H. medioplexus in the variable D1 region of the 28s rDNA, complementing the morphological differences.

A new particle of chromatin obtained by proteolysis of histones with clostripain

The proteolysis of the chromatin core particle by the arginine-specific endopeptidase clostripain yields a new nucleoprotein particle containing an unaltered DNA fragment of about 145 base pairs in length and a protein octameric core made up of twice the four histone fragments H2A, H2B, H3 and H4. This composition is suggested by the molecular weight of about 180 kd determined for the new particle by small angle neutron scattering. The histone fragments differ by about 2-3 kd each from the initial histones H2A, H2B, H3 and H4 and they correspond to the cleavage of the N-terminal part of the sequence (20-30 residues). A preliminary investigation by thermal denaturation, circular dichroism and small angle neutron scattering (measurement of a radius of gyration by the H2O-D2O contrast variation technique) indicates that the spatial organization of the new chromatin particle closely resembles that of the initial core particle.
