Plant-specific TEOSINTE-BRANCHED1/CYCLOIDEA/PCF (TCP) transcription factors play crucial roles in development, but their functional mechanisms remain largely unknown. Here, we characterized the cellular functions of the class I TCP transcription factor GhTCP14 from upland cotton (Gossypium hirsutum). GhTCP14 is expressed predominantly in fiber cells, especially at the initiation and elongation ...

BACKGROUND When anatomic obstacles preclude radiofrequency catheter ablation of idiopathic ventricular arrhythmias (VAs) originating from the left ventricular outflow tract (LVOT), an alternative approach from the anatomically opposite side (endocardial versus epicardial or above versus below the aortic valve) may be considered (anatomic ablation). The purpose of this study was to investigate t...

In the allopolyploid Brassica napus, we obtained a petal-closed flower mutation by ethyl methanesulfonate mutagenesis. Here, we report cloning and characterization of the Bn-CLG1A (CLG for cleistogamy) gene and the Bn-clg1A-1D mutant allele responsible for the cleistogamy phenotype. Bn-CLG1A encodes a RINGv E3 ubiquitin ligase that is highly conserved across eukaryotes. In the Bn-clg1A-1D mutan...

in order to determine the appropriate plant density of spotted bean in yasouj, a field experiment was conducted in 2008 as a factorial in a randomized complete block design with three replications. three spotted bean cultivars (keshavarzi, talash and oshtori) were sown at five plant densities (10, 20, 30, 40 and 50 plant.m-2). results showed that effect of plant density, cultivar and interactio...

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...

grass pea (lathyrus sativus l.) has a high potential for forage production inboth rangelands and cultivated rainfed areas of iran. it is well adapted to semi-arid areas ofwest and north of country where annual rainfall is 250–350 mm. to study the seed and drymatter (dm) yield and agronomic traits, six genotypes of lathyrus sativus l. and twogenotypes of lathyrus inconspicuous l. were provided b...

abstract the critical period of weed control (cpwc) is a period in the crop growth cycle during which weeds must be controlled to prevent yield losses. in order to determine the critical period of weed control (cpwc) of corn in hamedan, an experiment was conducted in 2007 at agricultural research station of bu-ali sina university of hamedan. the experiment was carried out as a randomized comple...

Flowering time control is important for fruit production in Fragaria × ananassa. The flowering inhibition pathway has been extensively elucidated in the woodland strawberry, Fragaria vesca, whereas the factors involved in its promotion remain unclear. In this study, we investigated the environmental responses of F. × ananassa FT and TFL1-like genes, which are considered key floral promoters and...

Invariant petal number is a characteristic of most flowers and is generally robust to genetic and environmental variation. We took advantage of the natural variation found in Cardamine hirsuta petal number to investigate the genetic basis of this trait in a case where robustness was lost during evolution. We used quantitative trait locus (QTL) analysis to characterize the genetic architecture o...
