There is considerable variability in salt tolerance amongst members of the Triticeae, with the tribe even containing a number of halophytes. This is a review of what is known of the differences in salt tolerance of selected species in this tribe of grasses, and the potential to use wild species to improve salt tolerance in wheat. Most investigators have concentrated on differences in ion accumu...
Stem rust (caused by Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. & E. Henn.), a devastating disease of wheat (Triticum aestivum L.), was effectively controlled worldwide for the past 50 yr by deployment of stem rust resistance (Sr) genes in wheat cultivars. However, a new stem rust race, TTKSK (known as Ug99 or TTKS) that emerged in eastern Africa, is a cause of concern because it has b...
introduced in this inquiry and review is a balladry which exists both in divan of hassan ghaznavi and attar. in addition, the existing differences between the two also revealed balladry, and some lines in this ode were corrected according to divan of hassan ghaznavi. it is very important to note that the opening sixteen lines of this ode, except for the 7th and 8th lines, have been attributed t...
COMPARED to studies based on ordinary homozygous varieties, the use of chromosome substitution lines obtained by means of aneuploid series in Triticum uestiuum L. (SEARS 1944, 1953; UNRAU, PERSON and KUSPIRA 1956; PERSON 1956) permits a more complete, detailed and reliable analysis of the genetic structure of hexaploid wheats (KUSPIRA and UNRAU 1957; SEARS, LOEGERING and RODENHISER 1957; LOEGER...
The frequency of chromosome abnormalities in spontaneous abortions, stillbirths, livebirths and among all clinically recognized pregnancies is given. Data on the parental origin of sex chromosome abnormalities and certain autosomal trisomies determined using molecular probes are presented and the proportion of sperm and eggs that are nullisomic or disomic for a sex chromosome to an autosome 16,...
The genes encoding 18S, 5.8S, and 28S ribosomal RNA (rRNA) are tandemly repeated at the nucleolus organizer region (NOR). The NORs in the chicken map to one pair of microchromosomes. A line of chickens that contains individuals that are either disomic, trisomic, or tetrasomic for this chromosome, and have two, three, or four nucleoli and NORs, per cell, respectively, has been described previous...
In order to have a sustainable management on Persian sturgeon as a highly commercial species in the South Caspian Sea, we need to identify its population structure and the level as well as its conservation status in their natural habitat. To develop a conservation program for this all Caspian Sea' sturgeon species it requires knowledge of its genetic diversity using reliable molecular...
