High temperature stress results in yield loss and alterations to seed composition during seed filling in oilseed rape (Brassica napus). However, the mechanism underlying this heat response is poorly understood. In this study, global transcription profiles of 20 d-old siliques of B. napus were analyzed after heat stress using a Brassica 95k EST microarray. The up-regulated genes included many HS...

Each cotton fiber is a single-celled seed trichome or hair, and over 20,000 fibers may develop semi-synchronously on each seed. The molecular basis for seed hair development is unknown but is likely to share many similarities with leaf trichome development in Arabidopsis. Leaf trichome initiation in Arabidopsis thaliana is activated by GLABROUS1 (GL1) that is negatively regulated by TRIPTYCHON ...

Auxin plays an essential role in regulating Arabidopsis growth and development. YUCCA (YUC) family genes encode flavin monooxygenases, which are rate-limiting enzymes the auxin biosynthetic pathway. Previous studies showed that YUC8 overexpression (YUC8 OE), as well ectopic expression of driven by GL2 (GLABRA 2) TT12 (TRANSPARENT TESTA 12) promoters, specifically expressed epidermis inner seed ...

To appraise the effect of drought stress on foraging behavior (visitation frequency and visitation rate) insect pollinators its ultimate impact reproductive success canola (Brassica napus L.), an experiment was carried out at Research Farm MNSUniversity Agriculture, Multan, Pakistan. Previously, only a few studies have evaluated as predictor plant-pollinator interactions. Normal irrigated plots...

Metabolism of the alpha-1,1 glucose disaccharide, trehalose, is indispensable in plants. In the Murashigeand Skoog (MS) medium, trehalose inhibits plant growth and allocation of carbon to roots. A suppressorof trehalose-6-phosphate (T6P) mediated growth arrest, GR-RBP2, is characterized in more detail.Phylogenetic analysis revealed that GR-RBP2 is a protein of likely prokaryot...

in order to investigate lentil response to application times and amounts of zinc, an experiment was arranged as factorial based on randomized complete block design with four replications on farm research of gonbad higher education center during 2008-2009. treatments were application times (before flowering and beginning of pod setting) and application rates (0, 0.5, 1, 1.5 and 2 liter per hecta...

Trichoderma is a genus of filamentous fungi with highly beneficial species for use in agriculture due to its ability combat disease, increase growth, tolerance abiotic stresses and resistance biotic plants. To do this, must effectively colonize the roots plant, being able overcome existing plant defenses. In this sense, glucosinolates (GSLs) are group secondary metabolites present cruciferous d...

Brassica napus L. is an important oil crop worldwide and is the main raw material for biofuel. Seed weight and seed size are the main contributors to seed yield. DA1 (DA means big in Chinese) is an ubiquitin receptor and negatively regulates seed size. Down-regulation of AtDA1 in Arabidopsis leads to larger seeds and organs by increasing cell proliferation in integuments. In this study, BnDA1 w...

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...

Seed morph, abiotic conditions and time of germination can affect plant fitness, but few studies have tested their combined effects on plasticity of plant life history traits. Thus, we tested the hypothesis that seed morph, germination season and watering regime influence phenotypic expression of post-germination life history traits in the diaspore-heteromorphic cold desert winter annual/spring...
