Dynamics of heat-shock induced DNA damage and repair in senescent tobacco plants
Biologia Plantarum, 2014 Oxidative stress plays an important role in plant ageing and in response to different stresses. Oxidative DNA damage, unless repaired, may have detrimental consequences and increase genetic instability.

Molecular characterization and genetic diversity of potato cultivars using SSR and RAPD markers.
, 2010 Este trabalho teve como objetivo avaliar a divergencia genetica e identificar cultivares de batata por meio de marcadores RAPD e SSR. O DNA genomico de 16 cultivares de batata foi amplificado com primers RAPD e com pares de primers SSR.

Genetic diversity in white clover and its progenitors as revealed by DNA fingerprinting
Biologia Plantarum, 2012 The genetic diversity and ancestral relationships of a number of Trifolium species was revealed by using the amplified fragment length polymorphism (AFLP) and the random amplified polymorphic DNA (RAPD) markers. Both markers produced few species-specific

Molecular profiling of chickpea mutants isolated from EMS and gamma rays treatments [PDF]
Ratarstvo i Povrtarstvo, 2019 Conventional mutation breeding techniques have often been used to improve yield, disease and pest resistance in crop plants. In the present attempt, two well-known mutagenic agents ethyl methane sulphonate and EMS were employed in order to induce genetic

Plant regeneration in Curcuma species and assessment of genetic stability of regenerated plants
Biologia Plantarum, 2010 An efficient plant regeneration protocol was developed from rhizomes of two Curcuma species C. longa and C. amada. Response was highly dependent on the season, with above 69 % of culture developing adventitious shoots during spring. Greatest regeneration

Microwave treatment induced mutations and altered gene expression in Vigna aconitifolia
Biologia Plantarum, 2010 Primary leaf explants of aseptically grown seedlings of moth bean [Vigna aconitifolia (Jacq.) Marechal] immersed in water or not were treated in microwave oven (2450 MHz, 800 W cm-2) for 1, 3, 5 and 7 s before culturing.

Identification of olive (Olea europaea L.) cultivars by molecular markers
Acta Agriculturae Slovenica, 2001 RAPD markers were applied to assess molecular polymorphisms within olive cultivars held in a collection orchard and to develop a system of a minimum number of primers for cultivar identification.
