Sensory exploitation predicts that female mate preferences exist before the evolution of exaggerated male ornaments. We tested this prediction by estimating female preference functions, remating intervals, and copulation durations for three species of stalk-eyed flies. Two species, Cyrtodiopsis whitei and C dahnanni, exhibit extreme sexual dimorphism in eye span, with eye stalks exceeding body ...

tion procedure (Lachat Instruments, Milwaukee; Method 12-107-04-1-B) to determine NO3 concentration The end-of-season stalk NO3 test has been used to determine N in aliquots of filtered extracts prepared by shaking sufficiency in corn (Zea mays L.). Nitrate concentration is commonly known weights of ground stalk material for 30 min in determined with flow-injection analysis (FIA), which is accu...

saffron is the most important iranian non oil export. improper conditions of saffron flower storage increases microbial contamination and decreases saffron quality. this study was done for prolonging the shelf life of saffron flower in modified atmosphere packaging and subsequent to producing a new method for exporting the fresh saffron flower as cut flower. saffron flowers were packed in a pol...

Based on next-generation sequencing data, we assembled the mitochondrial (mt) genome of date palm (Phoenix dactylifera L.) into a circular molecule of 715,001 bp in length. The mt genome of P. dactylifera encodes 38 proteins, 30 tRNAs, and 3 ribosomal RNAs, which constitute a gene content of 6.5% (46,770 bp) over the full length. The rest, 93.5% of the genome sequence, is comprised of cp (chlor...

In order to investigate the effect of humic acid (HA) and nano-calcium chelate on the cut flowers of gerbera cv. Dune, an experiment was performed as a completely randomized design with two factors and three replications in hydroponic conditions. The first factor included humic acid at 4 concentrations of 0 (control), 500, 1000, and 2000 mg L-1 as drench and the second factor was ass...

The inhibition of axon regeneration upon mechanical injury is dependent on interactions between Nogo receptors (NgRs) and their myelin-derived ligands. NgRs are composed of a leucine-rich repeat (LRR) region, thought to be structurally similar among the different isoforms of the receptor, and a divergent "stalk" region. It has been shown by others that the LRR and stalk regions of NgR1 and NgR2...

violet is one of the ornamental plants with a good value in landscaping and herbal medicine. salicylic acid is a signaling agent involving in secondary metabolite production. the aim of this study was to evaluate the physiological responses of violet flowers to exogenous salicylic acid. this experiment was conducted in the greenhouse, as a completely randomized design. salicylic acid was spraye...
