A suite of interacting processes and mechanisms enables tolerance of desiccation and storage (conservation) of orthodox seeds in the dry state. While this is a long-term option under optimized conditions, dry orthodox seeds are not immortal, with life spans having been characterized as short, intermediate and long. Factors facilitating desiccation tolerance are metabolic "switch-off" and intrac...

This study aimed to evaluate the Mangaba Genebank of Embrapa Tabuleiros Costeiros, Brazil, since its implementation in 2006 and characterize accessions reproductive stage. We used 21 descriptors (botanical, morphological, growth, biometric, physicochemical) assess mangaba germplasm, as well data enrichment survival genebank implementation. There was a success enrichment, maintenance, diversity ...

Exploitation of wild relatives of crop plants to a large extent depends on the efficient use of germplasm resources available in natural habitat and the centre of diversity. The mulberry, sole food for silkworm is cultivated for the production and development of silkworm industry. Four species of mulberry viz., M. indica L., M. alba L., M. laevigata Wall., and M. serrata Roxb., are reported in ...

Our ability to manage gene flow within traditional agroecosystems and their repercussions requires understanding the biology of crops, including farming practices' role in crop ecology. That these practices' effects on crop population genetics have not been quantified bespeaks lack of an appropriate analytical framework. We use a model that construes seed-management practices as part of a crop'...

The balloon flower (Platycodon grandiflorum A. DC.) is a perennial flowering plant of the Campanulaceae family; it is the only member of the genus Platycodon. Information on the genetic diversity of balloon flower populations is of great importance for the conservation and germplasm utilization of this flowering plant. Twenty-two polymorphic microsatellite loci were developed and character...

To meet the growing demands under the constrains of depleting natural resources, environmental fluctuation and increased risk of epidemic outbreak, the task of increasing wheat production has become daunting. The euphoria generated by first green revolution is very quickly subsiding and the second generation problems are becoming more intense with each passing year. The factors responsible for ...

AFLP analyses were used to assess the genetic similarity among selected accessions at the South China Tobacco Breeding Research Centre (Yunnan province, Southwest China). 154 AFLP polymorphic fragments out of 561 fragments were used to assess the genetic diversity among 28 tobacco accessions. The average number of polymorphic bands per AFLP primer pair was 15.4. AFLPs seemed to be an effective ...
