Plant morphogenesis is profoundly influenced by light (a phenomenon known as photomorphogenesis). For example, light inhibits seedling hypocotyl growth via activation of phytochromes and additional photoreceptors. Subsequently, information is transmitted through photoreceptor-linked signal transduction pathways and used (via previously unknown mechanisms) to control hypocotyl growth. Here we sh...

Arabidopsis thaliana flowers emit volatile terpenes, which may function in plant-insect interactions. Here, we report that Arabidopsis MYC2, a basic helix-loop-helix transcription factor, directly binds to promoters of the sesquiterpene synthase genes TPS21 and TPS11 and activates their expression. Expression of TPS21 and TPS11 can be induced by the phytohormones gibberellin (GA) and jasmonate ...

Objective: This study was conducted to examine the relationships between dispositional mindfulness, temperament, personality traits, and identity styles and to determine the predictive power of dispositional mindfulness, temperament, personality traits in identity styles. Methods: 223 students (120 females and 103 males) from the universities in Tehran were selected as the sample. The data wer...

Severe Arabidopsis (Arabidopsis thaliana) gibberellin (GA)-deficient mutant ga1-3 fails to germinate and is impaired in floral organ development. In contrast, the ga1-3 gai-t6 rga-t2 rgl1-1 rgl2-1 mutant confers GA-independent seed germination and floral development. This fact suggests that GA-regulated transcriptomes for seed germination and floral development are DELLA dependent. However, it ...

the present study pursued two goals: first, to discover the subscales underlying the teacher status scale (tss); and second, to reveal the status of the teachers of persian, arabic, and english in iranian junior high school students’ perceptions in order to determine the relative roles of national, religious, and western influences in the identity construction of the students. the data was coll...

In plants, light represents an important environmental signal that triggers the production of photosynthetically active chloroplasts. This developmental switch is critical for plant survival because chlorophyll precursors that accumulate in darkness can be extremely destructive when illuminated. Thus, plants have evolved mechanisms to adaptively control plastid development during the transition...

BACKGROUND Patients with borderline personality disorder (BPD) suffer from instability of their relationships, their affectivity and their identity. The purpose of the study was to investigate negative affects and identity disturbance in patients with BPD and in patients without personality disorder using questionnaire data and interview data. SAMPLING AND METHODS Twelve patients with BPD and...
