Abstract Aims Since gravitropism is one of the primary determinants root development, facilitating penetration into soil and subsequent absorption water nutrients, we studied this response in rice. Methods The 226 Chinese rice micro-core accessions drought-resistant core were assessed through modified gravity-bending experiment genome-wide association analysis (GWAS) was used to map associated ...

this study was conducted for the first time in order to introduce the pioneer forest trees and medicinal sea-buckthorn (elaeagnus rhamnoides) and determine the characteristics of the species seeds from seven provenances, including iran, china and tibet in the laboratory. after site identification of the species, seeds were collected from the regions including alborz, mazandaran, eastern azerbai...

This work was conducted on the use of RE (radicle emergence) test to estimate seedling emergence (SE) and quality (seedling shoot weight (SSW), root (SRW) height (SH)) twelve hybrid cucumber seed lots with high germination (>95%) at low temperature conditions, salt conditions a combination two. The percentages RE, which is 2 mm radicle protrusion 25 °C in dark, were counted between 18 h 32 h...

the genus thymus is perennial medicinal plants belong to the lamiaceae familythat is used for different propose in pharmaceutical industry. environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. the purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...

Globin makes up 95 per cent of the hemoglobin molecule. Its construction is of fundamental importance. It is a protein and its production in the body relates to the building stones of protein and to other body proteins. In fact plasma protein introduced into a fasting anemic dog will bring about a large output of new hemoglobin (globin). Globin production and the related hemoglobin can be contr...

The phas promoter displays stringent spatial regulation, being very highly expressed during embryogenesis and completely silent during all phases of vegetative development in bean, Phaseolus vulgaris. This pattern is maintained in transgenic tobacco and, as shown here, Arabidopsis. Dimethyl sulphate in vivo footprinting analyses revealed that over 20 cis-elements within the proximal 295 bp of t...
