We present a five dimensional supersymmetric SO(10) model compactified on an orbifold S/Z2 ×Z ′ 2. The gauge symmetry G422 ≡ SU(4)c×SU(2)L×SU(2)R, realized on one of the fixed points (branes), is spontaneously broken to the MSSM via the higgs mechanism. Employing a flavor U(1) symmetry and suitably extending the ’matter’ sector enables us to understand large mixings in the neutrino sector via a...

Let G̃ be a simple algebraic group which is defined and split over a field K and let L̃ be a corresponding Lie algebra. Further, let R be the corresponding root system. We prove here that if char K = 0 or a very good prime for R and | K |>| R |, then there exists an orbit O ⊂ L = L̃(K) with respect to the adjoint action of G = G̃(K) such that L = O + O. This is an analogue of the corresponding resu...

The effects of different nodal positions and 6-benzylaminopurine (BAP) concentrations on shoot development from nodal explants of Hemidesmus indicus (L.) Br. (Iramusu) were investigated. The highest number of shoots per explant (2.57±0.97) was observed in 4 nodal position, while the longest shoot length (3.23± 0.52 cm) was achieved in 5 nodal position at 2 mg/L BAP with 0.1 mg/L Naphthalene Ace...

Six rotenoids have isolated from Indigofera tinctoria, characterized by means of their spectral data and/or co-tlc. The total estimation studies revealed that rotenol was major rotenoid in both in vivo and in vitro. Similarly, by elicitation studies, we observed that summatrol synthesis was higher at the concentration of 0.01 mM ergosterol and salicylic acid. Among all sequential fractions, met...

Pearl millet is a climate resilient crop and one of the most widely grown millets worldwide. Heterotic hybrid development is one of the principal breeding objectives in pearl millet. In a maiden attempt to identify heterotic groups for grain yield, a total of 343 hybrid parental [maintainer (B-) and restorer (R-)] lines were genotyped with 88 polymorphic SSR markers. The SSRs generated a total ...

We have developed two types of mechanical models of the human vocal tract. The first model was designed for the retroflex approximant [r] and the alveolar lateral approximant [l]. It consisted of the main vocal tract and a flapping tongue, where the front half of the tongue can be rotated against the palate. When the tongue is short and rotated approximately 90 degrees, the retroflex approximan...

The objective of this study was to identify morphological and physiological traits for salinity tolerance in Tunisian autochthonous ZZ pearl millet ecotype (Pennisetum glaucum (L.) R. Br) under local conditions. ZZ ecotype was cultivated under different levels of salinity and growth parameters, water relations and mineral content were measured. Results showed that ZZ pearl millet ecotype was un...

A simple, genotype-independent and efficient method for plant regeneration using shoot tip explants of pearl millet (Pennisetum glaucum) was established. Linsmaier and Skoog (LS) medium supplemented with 2,4-dichloro-phenoxyacetic acid (2.5 mg l(-1)) and kinetin (0. 2 mg l(-1)) was used for induction of embryogenic calli. Development of numerous somatic embryos was observed within 10 days after...
