Studies conducted in controlled environments showed that seed priming and foliar treatments with various bioactive substances can stimulate germination, uniform seedling emergence, photosynthesis, nutrient uptake efficiency lead to increased productivity, crop stand, quality. Only a few studies provide comparative experimental outlook about the use of open-field cultivated canola. The aim this ...

In this study, TaTEF-7A, a member of the transcript elongation factor gene family, and its flanking sequences were isolated. TaTEF-7A was located on chromosome 7A and was flanked by markers Xwmc83 and XP3156.3. Subcellular localization revealed that TaTEF-7A protein was localized in the nucleus. This gene was expressed in all organs, but the highest expression occurred in young spikes and develop...

in order to identify the suitable rapeseed genotypes as second crop in paddy fields of guilan province, 14 rapeseed genotypes were grown in complete randomized block design with three replicates in a paddy fields experimental condition in rice research institute of iran, rasht during 2005-2007 cropping seasons. the results of the combined analysis of variance indicated significant difference am...

Seasonal behavior is important for fitness in temperate environments but it is unclear how progeny gain their initial seasonal entrainment. Plants use temperature signals to measure time of year, and changes to life histories are therefore an important consequence of climate change. Here we show that in Arabidopsis the current and prior temperature experience of the mother plant is used to cont...

This study was aimed description of morphological features fruits and seeds eight species related to Brassicaceae family in Iraq, the showed number taxonomic differences as silique long all studied except Rorippa amphibian (L.)b Besser short, however varied dimensions where Turritis laxa L. recorded highest average length with (160 mm) while R .amphibia record shortest (5 mm), addition colors r...

five genotypes of chickpea as a half diallel crossed with each other, in 2008, 5 parents and 10 progenies were planted as randomized complete block design and some traits including days to podding, basal pod height, number of pods per plant, number of double seed pods per plant, number of single seed pods per plant, number of empty pods per plant, seeds per plant and seed yield per plant were e...

drought stress is one of the important problems in arid and semi_arid regions. drought stress take place in plants when available water is lesser than evapotranspiration. in order to evaluate the effect of drought stress on morphological traits and yield of three medicinal plants an experiment was carried out during the 2010 year in research greenhouse of faculity of agriculture, ferdowsi unive...

abstract- to investigate the effect of draught stress on water relations, stomatal density, chlorophyll content and yield of rapeseed, an experiment was done with four levels of drought stress including l1 (field capacity, fc), l2 (70% available water content, awc), l3 (50% awc), and l4 (30% awc), within three growth stages- including stem elongation (t1), onset of flowering (t2) and silique fo...

The enzyme 3-ketoacyl-CoA thiolase (KAT) (EC 2.3.1.16) catalyses a key step in fatty acid beta-oxidation. In Arabidopsis thaliana, expression of the KAT2 gene is known to be required for the efficient mobilization of triacylglycerol during germination and seedling establishment. Here, data from the Arabidopsis kat2-1 mutant are presented, showing that perturbation of beta-oxidation also affects...

Cell separation is thought to involve degradation of pectin by several hydrolytic enzymes, particularly polygalacturonase (PG). Here, we characterize an activation tagging line with reduced growth and male sterility caused by increased expression of a PG encoded by QUARTET2 (QRT2). QRT2 is essential for pollen grain separation and is part of a small family of three closely related endo-PGs in t...
