De novo sequencing and development of EST-SSR for Gevuina avellana (Proteaceae), a nut tree from South America.

Unlabelled: •

Premise Of The Study: The aim of this study was to develop molecular tools to investigate the genetic structure and diversity of natural populations of Gevuina avellana (Molina, Proteaceae), the Chilean hazelnut. Simple sequence repeats (SSRs) derived from expressed sequence tags (EST-SSRs) were developed, optimized, and characterized. •

Methods And Results: The microsatellite-containing sequences were selected from a cDNA library developed from the nut.

[Evaluation of trap color and position on the capture of cicadellids in Gaultheria phillyreifolia (Ericaceae) affected by phytoplasmas].

Color sticky traps are one of the main alternatives to collect insect vectors, as they are easy to handle and are inexpensive. We aimed to compare the effect of color and height of the traps on the attractiveness to potential cicadellids vectors of plant pathogens. Yellow and green colored stick traps were placed at two different heights in plant of Gaultheria phillyreifolia.

Expansins expression is associated with grain size dynamics in wheat (Triticum aestivum L.).

Grain weight is one of the most important components of cereal yield and quality. A clearer understanding of the physiological and molecular determinants of this complex trait would provide an insight into the potential benefits for plant breeding. In the present study, the dynamics of dry matter accumulation, water uptake, and grain size in parallel with the expression of expansins during grain growth in wheat were analysed.
