Genetic diversity of an Azorean endemic and endangered plant species inferred from inter-simple sequence repeat markers

Abstract

Picconia azorica is an endangered endemic species of the Azores whose hard and high density wood is very appreciated for the production of toys, agricultural tools, furniture and religious statuary. Its renewed economic interest represents a good opportunity for establishing conservation programmes. To contribute with information useful for the decision making we performed the genetic analysis of 230 samples from 11 populations collected in three Azorean islands. The majority of the genetic variability was found within populations and no genetic structure was detected between populations and between islands, indicating that the oceanic barriers do not greatly affect gene flow.

Genetic diversity and population structure of the endemic Azorean juniper, Juniperus brevifolia (Seub.) Antoine, inferred from SSRs and ISSR markers

“…Similar patterns of low differentiation among populations have also been reported in other insular trees of the Macaronesia as Morella faya, Morella rivas-martinezzi and endemic Picconia azorica (Gonz alez-P erez et al, 2009;Ferreira et al, 2011;Lopes et al, 2014). Furthermore our results agree in part with Silva et al (2011) that reported a low geographical structure between islands but not between populations.…”

Analysis of genetic structure of Ranunculus baudotii in a Mediterranean wetland. Implications for selection of seeds and seedlings for conservation

“…The results corroborate the usefulness of ISSR markers in setting priorities and planning optimal actions for the conservation of endangered plant species or populations in threatened biotopes (Thompson, 2005;Lopes et al, 2014).…”

Variability and interpopulation differentiation of the rare species Gueldenstaedtia monophylla Fisch. (Fabaceae)

“…Уровень генети-ческого разнообразия редких видов может существенно влиять на способность их популяций адаптироваться к изменениям окружающей среды и, следовательно, на их дальнейшее выживание (Примак, 2002;Frankham et al, 2002). Невозможно оценить перспективы дальнейшего существования вида без знания генетической структу-ры его популяций (Frankham, 2003;Gordon et al, 2012;Lopes et al, 2014). Для поддержания генетического раз-нообразия в популяциях очень важен размер популяции (Frankham, 2005).…”
