The present paper deals with the secondary metabolite contents such as saponin, total tannin and anthraquinone during three different developmental stages vegetative, flowering fruiting in Alhagi maurorum from Rajasthan desert. study of this plant is needed due to its higher medicinal values. aim quantitative estimation selected metabolites. amounts were evaluated by HPLC, titrimetric GC/MS/MS ...

A late-flowering mutant was isolated from rice T-DNA-tagging lines. T-DNA had been integrated into the K-box region of Oryza sativa MADS50 (OsMADS50), which shares 50.6% amino acid identity with the Arabidopsis MADS-box gene SUPPRESSOR OF OVEREXPRESSION OF CO 1/AGAMOUS-LIKE 20 (SOC1/AGL20). While overexpression of OsMADS50 caused extremely early flowering at the callus stage, OsMADS50 RNAi plan...

prangos ferulacea (apiaceae) is a perennial herb with a distribution from east europe to middle east and central asia. the plant’s leaves are used as animal fodder. its fruits and roots possess biological traits that provide it with the potential to be used for medicinal purposes. the essential oils obtained through hydrodistillation from aerial parts of prangos ferulacea at the vegetative and ...

Rice hull, the outer cover of the rice grain, determines grain shape and size. Changes in the rice hull proteome in different growth stages may reflect the underlying mechanisms involved in grain development. To better understand these changes, isobaric tags for relative and absolute quantitative (iTRAQ) MS/MS was used to detect statistically significant changes in the rice hull proteome in the...

Drought is one of the most important abiotic stresses that impair sesame (Sesamum indicum L.) productivity mainly when it occurs at flowering stage. However up to now, very few studies have attempted to investigate the molecular responses of sesame to drought stress. In this experiment, two genotypes having contrasting responses to drought (tolerant and sensitive) were submitted to progressive ...

In Oncidium, redox homeostasis involved in flowering is mainly due to ascorbic acid (AsA). Here, we discovered that Oncidium floral repression is caused by an increase in AsA-mediated NO levels, which is directed by the enzymatic activities of nitrate reductase (NaR) and nitrite reducatase (NiR). Through Solexa transcriptomic analysis of two libraries, 'pseudobulb with inflorescent bud' (PIB) a...

The transition to flowering involves major changes in the shoot apical meristem and in the fate of existing leaf primordia. Transcripts of the Arabidopsis thaliana flowering-promoting gene FLOWERING LOCUS T (FT) are present in leaf tissue but can also promote flowering when artificially introduced into the meristem. FT may normally act in the leaf and/or the meristem, initiating or constituting...

to study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and oil percentage of goldasht spring safflower cultivar, an experiment was carried out in 2012 in the agricultural research farm station of islamic azad university, roudehen branch as split plot in a completely randomized blocks design with three replications. in ...
