Cotton is the most important textile crop as a result of its long cellulose-enriched mature fibers. These single-celled hairs initiate at anthesis from the ovule epidermis. To date, genes proven to be critical for fiber development have not been identified. Here, we examined the role of the sucrose synthase gene (Sus) in cotton fiber and seed by transforming cotton with Sus suppression construc...

in order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of goldasht spring safflower cultivars (carthamus tinctorius l.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the agricultural research station of islamic azad university of roudehen branc...

We study the early growth of massive seed black holes (BHs) via accretion in protogalactic nuclei where stellar bulge component is assembled, performing axisymmetric two-dimensional radiation hydrodynamical simulations. find that when a BH with $M_\bullet \sim 10^5~M_\odot$ embedded dense metal-poor gas ($Z=0.01~Z_\odot$) density $\gtrsim 100~{\rm cm}^{-3}$ and stars total mass $M_\star \gtrsim...

Abstract Producing seeds from shallot flower requires proper pollination techniques to form pithy seeds. This study aims determine the effectiveness of several methods in producing true (TSS). The research was conducted Cilame Village, Ngamprah District, West Bandung Regency, Java at an altitude 900 m asl. used a completely randomized design (CRD) which consisted four treatments and six replica...

NSF and NASA sponsored a workshop to discuss harvesting solar power in space. One solution considered was the use of a swarm of robots to form a solar reflector. How can these robots organize to form a large parabolic structure and be effectively controlled? The approach of this project is to treat the formation as a lattice of cells. Each cell is in one of a given state governed by a set of ru...

Postembryonic organ formation in higher plants relies on the activity of stem cell niches in shoot and root meristems where differentiation of the resident cells is repressed by signals from surrounding cells. We searched for mutations affecting stem cell maintenance and isolated the semidominant l28 mutant, which displays premature termination of the shoot meristem and differentiation of the s...

Multiple seed formation by three-dimensional twinning at the initial stages of growth explains the manifold of orientations found when self-catalyzed GaAs nanowires grow on silicon. This mechanism can be tuned as a function of the growth conditions by changing the relative size between the GaAs seed and the Ga droplet. We demonstrate how growing under high V/III ratio results in a 100% yield of...

We estimate the probability that a hard nucleon-nucleon collision is able to nucleate a seed of quark{gluon plasma in the surrounding hot and dense hadronic matter formed during a central collision of two large nuclei at AGS energies. The probability of producing at least one such seed is on the order of 1-100%. We investigate the in uence of quark{gluon plasma formation on the observed multipl...
