“…As far as composition is concerned in the compact stars the matter is found to be in stable ground state where the quarks are confined inside the hadrons. It is argued by several workers [26,27,28,29] that if it is composed of the de-confined quarks then also a stable ground state of matter, known as 'strange matter', is achievable which provides a 'strange star'. There are two aspects of this assumption behind strange star: (i) theoretically to explain the exotic phenomena of gamma ray bursts and soft gamma ray repeaters [30,31], and (ii) observationally confirmation of SAX J1808.4-3658 as one of the candidates for a strange star by the Rossi X-ray Timing Explorer [32].…”

In the present paper we develop an algorithm for all spherically symmetric anisotropic charged fluid distributions. Considering a new source function ν(r ) we find a set of solutions which is physically well behaved and represents compact stellar models. A detailed study specifically shows that the models actually correspond to strange stars in terms of their mass and radius. In this connection we investigate several physical properties like energy conditions, stability, mass-radius ratio, electric charge content, anisotropic nature and surface redshift through graphical plots and mathematical calculations. All the features from these studies are in excellent agreement with the already available evidence in theory as well as observations.

We have proposed a model for relativistic compact star with anisotropy and analytically obtained exact spherically symmetric solutions describing the interior of the dense star admitting non-static conformal symmetry. Several features of the solutions including drawbacks of the model have been explored and discussed. For this purpose we have provided the energy conditions, TOV-equations and other physical requirements and thus thoroughly investigated stability, mass-radius relation and surface redshift of the model. It is observed that most of the features are well matched with the compact stars, like quark/strange stars.

“…These results indicate that overexpression of the ZmHDZIV13 gene plays an important role in increasing the expression of six marker genes in transgenic plants, and they also indicate that ZmHDZIV13 may participate in an ABA-dependent signal transduction pathway. The RD29B, RD22 and RD29A genes have been shown to be primarily involved in drought stress and ABA response [41] and can improve plant tolerance to stress, such as dehydration, and ABA induction [2,36,42]. Therefore, RD29B, RD22 and RD29A may be indirectly regulated by ABA induced by drought stress.…”

The homeodomain leucine zipper (HD-Zip) IV transcription factor is indispensable in the response of plants to abiotic stress. Systematic studies have been carried out in Arabidopsis, rice and other species from which a series of stress resistance-related genes have been isolated. However, the function of the HD-Zip-IV protein in maize is not clear. In this study, we cloned the HD-Zip-IV gene ZmHDZIV13 and identified its function in the stress response. Our phylogenetic analysis showed that ZmHDZIV13 and AtHDG11 had high homology and might have similar functions. The heterologous overexpression of ZmHDZIV13 in Arabidopsis resulted in sensitivity to abscisic acid (ABA), salt tolerance during germination and drought tolerance in seedlings. Under drought stress, the transgenic Arabidopsis showed stronger drought resistance than the wild-type showed (control). The malondialdehyde content of ZmHDZIV13 transgenic plants was lower than that of the control, and the relative water content and proline content were significantly higher than those of the control. After the drought was relieved, the expression of P5CS1, RD22, RD29B, RD29A, NCED3 and ERD1 were upregulated in transgenic Arabidopsis. Also, modified tobacco plants (35S::ZmHDZIV13) exhibited proper stomatal changes in response to drought conditions. These results show that ZmHDZIV13, as a stress-responsive transcription factor, plays a role in the positive regulation of abiotic stress tolerance and can regulate an ABA-dependent signaling pathway to regulate drought response in plants.
