    The physical traits of local almond populations from Morocco were studied to characterize their genetic resources and to evaluate the possibility of their commercial valorization. Nut weight ranged between 1.15 and 7.39 g, and kernel weight between 0.54 and 1.85 g, but most accessions were characterized by small kernels, pronounced wrinkles, and double kernels. Although the physical quality of the kernels of these populations was low, they show the possibility of some specialized uses, which could improve their marketable value. The genotypes with favorable values could be incorporated into an almond breeding program as parents to increase the kernel quality.Publishe

    Mutations in ZMYND10, a Gene Essential for Proper Axonemal Assembly of Inner and Outer Dynein Arms in Humans and Flies, Cause Primary Ciliary Dyskinesia

    Primary ciliary dyskinesia (PCD) is a ciliopathy characterized by airway disease, infertility, and laterality defects, often caused by dual loss of the inner dynein arms (IDAs) and outer dynein arms (ODAs), which power cilia and flagella beating. Using whole-exome and candidate-gene Sanger resequencing in PCD-affected families afflicted with combined IDA and ODA defects, we found that 6/38 (16%) carried biallelic mutations in the conserved zinc-finger gene BLU (ZMYND10). ZMYND10 mutations conferred dynein-arm loss seen at the ultrastructural and immunofluorescence level and complete cilia immotility, except in hypomorphic p.Val16Gly (c.47T>G) homozygote individuals, whose cilia retained a stiff and slowed beat. In mice, Zmynd10 mRNA is restricted to regions containing motile cilia. In a Drosophila model of PCD, Zmynd10 is exclusively expressed in cells with motile cilia: chordotonal sensory neurons and sperm. In these cells, P-element-mediated gene silencing caused IDA and ODA defects, proprioception deficits, and sterility due to immotile sperm. Drosophila Zmynd10 with an equivalent c.47T>G (p.Val16Gly) missense change rescued mutant male sterility less than the wild-type did. Tagged Drosophila ZMYND10 is localized primarily to the cytoplasm, and human ZMYND10 interacts with LRRC6, another cytoplasmically localized protein altered in PCD. Using a fly model of PCD, we conclude that ZMYND10 is a cytoplasmic protein required for IDA and ODA assembly and that its variants cause ciliary dysmotility and PCD with laterality defects

    Building Security through Insecurity: The Nigerian Military and Counter- Violence Campaigns in the Fourth Republic

    Since independence on October 1, 1960, Nigeria has been a victim, at one time or the other, of intra-ethnic, inter-ethnic, religious, and communal conflicts which have undermined the human security of her citizens. Nigeria’s corporate existence had also been threatened by 3 years (1967–1970) civil war which impacted negatively on the well-being of its people. In addition, the inability of the Nigerian Police to cope with the magnitude of the surge of violence in recent years has brought about the idea of involving the military, a core component of traditional security apparatus to deal with internal insecurity. This article is anchored on human security paradigm with reliance on secondary data to analyze the operations of the Nigerian Military in counterviolence campaigns between 1999 and 2017. This article points out that the involvement of the military in internal security has worsened the problem of insecurity due to the military’s unprofessional approach and, at times, deliberate targeting the civilian populace which it is supposed to protect. It, therefore, recommends among others, the need for the Federal Government of Nigeria to urgently review the role of the armed forces in addressing internal security situations in a way that will bring about respect for the rule of engagement in internal security operations and adherence to global best practices

    In trials conducted from 1975 through 1988, "Carmel" almond trees on Nemaguard and Lovell peach seedling rootstocks frequently had significantly higher yields than trees on almond seedling rootstocks, but there was no significant difference in yield between the two peach rootstocks. Lovell rootstock produced larger trees than Nemaguard or almond rootstocks, particularly with the "Carmel" cultivar. Leaf analysis showed that trees on almond root-stock had lower potassium and magnesium, and higher sodium, calcium and zinc levels than trees on the peach rootstocks

    Influência do ácido indolbutírico e ethefon no enraizamento de estacas de pessegueiro (Prunus persica (L.) Batsch) Influence of indolebutyric acid and ethephon on rooting of cuttings of peach (Prunus persica (L.) Batsch)

    Este trabalho foi conduzido no Departamento de Fitotecnia da Faculdade de Agronomia Eliseu Maciel, Universidade Federal de Pelotas, em estufa com nebulização intermitente, com o objetivo de verificar o efeito do ácido indolbutírico(AIB) e ethefon (ácido 2-cloroetil fosfônico) no enraizamento de estacas de ramos de pessegueiro. Utilizou-se estacas medianas retiradas de ramos de plantas com seis anos de idade, da cultivar Diamante, com comprimento de 15cm. Efetuou-se duas lesões laterais na base das estacas que foram tratadas com ácido indolbutírico nas concentrações 0; 1000; 2000 e 3000ppm, na forma líquida e, ethefon nas concentrações de 0; 50; 100 e 150ppm. Após a imersão de 5 segundos, acondicionou-se as estacas em sacos de polietileno contendo como substrato a mistura de areia+cinza (2:1 v/v). Pelos resultados obtidos concluiu-se que o ácido indolbutírico aumentou o percentual de estacas realizadas até a concentração de 1752ppm. e o número de raízes até a concentração de 1791ppm. O ethefon não apresentou resultados significativos na forma e concentração utilizadas.<br>This work was conducted at the Plant Science Departament Eliseu Maciel Agronomy College of Federal University of Pelotas, in greenhouse with intermitent mist, aiming to evaluate the effect of indolebutyric acid and ethephon (2-chloroetyl phosphonic acid) on peach hranch cutting rooting. Median cuttings with 15cm length removed from Diamante cultivar branch were used. Two lateral lesions were made on cutting basis and they were treated with indolebutyric acid in liquid at 0; 1000; 2000; and 3000ppm concentrations and ethefon at 0; 50; 100 and 150ppm concentrations. The immersion time was five seconds and the cuttings were packed in polietylene sacks containing a mixture of sand and rice husk ash substrate (2:1 v/v). Results showed that the indolebutyric acid increased the rooted cuttings percentage up to 1752ppm concentration and the number of roots until 1791ppm concentration. The ethephon did not show significant variation for the form and concentrations used
