In spermatophytes the ovules upon fertilization give rise to the seeds. It is essential to understand the mechanisms that control ovule number and development as they ultimately determine the final number of seeds and, thereby, the yield in crop plants. In Arabidopsis thaliana, ovules arise laterally from a meristematic tissue within the carpel referred to as placenta. For a correct determinati...

Domestication of many plants has correlated with dramatic increases in fruit size. In tomato, one quantitative trait locus (QTL), fw2.2, was responsible for a large step in this process. When transformed into large-fruited cultivars, a cosmid derived from the fw2.2 region of a small-fruited wild species reduced fruit size by the predicted amount and had the gene action expected for fw2.2. The c...

Plant organ size and thus plant size is determined by both cell proliferation and cell expansion. The bHLH transcription factor SPATULA (SPT) was originally identified as a regulator of carpel patterning. It has subsequently been found to control growth of the organs of the shoot. It does this at least in part by controlling the size of meristematic regions of organs in parallel to gibberellic ...

We isolated PTD, a member of the DEFICIENS (DEF) family of MADS box transcription factors, from the dioecious tree, black cottonwood (Populus trichocarpa). In females, in situ hybridization experiments showed that PTD mRNA was first detectable in cells on the flanks of the inflorescence meristem, before differentiation of individual flowers was visually detectable. In males, the onset of PTD ex...

Carpels are leaf-like structures that bear ovules, and thus play a crucial role in the plant life cycle. In angiosperms, carpels are the last organs produced by the floral meristem and they differentiate a specialized meristematic tissue from which ovules develop. Members of the three-amino-acid-loop-extension (TALE) class of homeoproteins constitute major regulators of meristematic activity. T...

In order to comprehend the plant resources' protection and management in every setting, genetic variousness research is required. Because of minimal number distinguishing morphological features, for example, leaf sequence carpel structure, Alcea includes a problematic taxonomy.34 species are reported Iran among them, 15 endemic. There no specifics. was studied using RAPD (Random Amplified Polym...

Objective: To study the morphological variations of median nerve observed in sick persons during carpal tunnel release operation. Study Design: Cross Sectional study. Setting: Qazi Hussain Ahmad Medical Complex, Nowshera. Period: One year (November, 2019 till October, 2020). Material & Methods: This Cross-sectional was conducted after obtaining ethical approval from Institutional Ethical Re...

Background: Carpal tunnel syndrome (CTS) is peripheral entrapment neuropathy in which compression of the median nerve at wrist occurs. Objective: To evaluate and study, ultrasound nerve-conduction predicting outcome after open surgical release carpel syndrome. Patients Methods: This prospective observational include 30 patients from out-patient Neurology orthopedic clinics Al Azhar Assuit Unive...

Kiwifruit (Actinidia chinensis) is a dioecious, long-living woody perennial vine. Reduced generation time and induction of hermaphroditism can accelerate crop improvement facilitate alternative farming for better food security in the face climate change. Previous studies identified that CENTRORADIALIS genes CEN CEN4 act to repress flowering, whilst male-specific Shy Girl (SyGl) gene with homolo...

Background: Human cornea expresses functional Fas-ligand capable of killing Fas+ activated lymphocytes. Fas expression is partly regulated by -670 A/G polymorphism in the promoter region of Fas gene. Objective: The aim of the present study is to determine the association between Fas-670A/G polymorphism and survival of corneal transplantation. Methods: In 276 graft recipients who mainly underwen...
