Carrots are a multi-purpose vegetable; hence, they have become very popular consumers’ choice, also thanks to their nutritional value with health benefits. Several varieties and landraces exist of carrot (Daucus carota L. ssp. sativus). In Apulia (Italy), for example, multicolored landrace is present, the Polignano (PC), threatened by risk genetic erosion. With purpose verifying possibility usi...

Lycium chilense, a deciduous perennial shrub, is one of the endangered native species of Patagonia due to sheep overgrazing. Chances of recolonization by seeds are scarce due to the limited density of propagules in the soil and very specific requirements for germination. The objective was to develop an in vitro propagation protocol that would help to perform reestablishment of this species in d...

Micropropagation of hemp ( Cannabis sativa ) is constrained by problems with hyperhydricity and culture decline microshoots. These can be reduced increasing agar nutrients in the media during micropropagation stages 1 2, respectfully. Performance microshoots ‘Abacus’ ‘Wife’ cultured Driver Kuniyuki Walnut medium (DKW) for 15 weeks (6 stage + 9 2), subculturing every 3 both or Murashige Skoog vi...

HIGHLIGHTS Agar is the most used gelling agent for plant culture medium, but it expensive. Gelling of medium with κ-carrageenan improves in vitro growth and direct indirect organogenesis Comanthera mucugensis. The use represents a 23.2% reduction cost producing compared agar. New studies are needed to improve rooting C.

Rubber tree (Hevea brasiliensis) self-rooting juvenile clones (JCs) are promising planting materials for rubber production. In a comparative trial between self-rooting JCs and donor clones (DCs), self-rooting JCs exhibited better performance in rubber yield. To study the molecular mechanism associated with higher rubber yield in self-rooting JCs, we sequenced and comparatively analyzed the late...

An effi cient protocol for organogenesis through leaves has been established for Launaea sarmentosa (Willd.) Sch. Bip. ex Kuntze, a highly valuable medicinal plant. The leaf explants produced microshoots on MS basal medium when fortifi ed with cytokinins and auxins. A combination of 6-benzylaminopurine (BAP) at 0.5mg/l and naphthaleneacetic acid (NAA) at 0.2mg/l resulted in the induction of hig...

Walnuts are considered recalcitrant to tissue culture, with a great genetic determinism on all stages of micropropagation; while other factors, also impact, become more complicated the reproduction newly realized varieties. In this research, holistic approach aimed determine influence genotype and nutritive formulation throughout whole cycle micropropagation four Persian walnut varieties (Jugla...

Romania has a relatively high diversity of plant species, including 3829 vascular and 979 non-vascular spontaneous taxa (species subspecies). Due to uncontrolled harvesting as well other causes, climate change ecological collapse, the speed species extinction narrowing genetic base resources been reported critical issue. Therefore, national Red List Romanian flora includes 1453 threatened taxa,...

Shoot tips of two fig cultivars (Conadria and Black Mission) proliferated in vitro, were cultured on modified MS medium supplemented with 0.5 mg/l 6-benzylaminopurine (BAP). The present investigation aimed to investigate the effect of different medium salt strengths (Double, full, half and quarter) and different sources of carbon (sucrose and fructose) at different concentrations (0.1 and 0.2 m...

A lack of competence to form adventitious roots by cuttings or explants in vitro occurs routinely and is an obstacle for the clonal propagation and rapid fixation of elite genotypes. Adventitious rooting is known to be a quantitative genetic trait. We performed a proteomic analysis of Arabidopsis (Arabidopsis thaliana) mutants affected in their ability to develop adventitious roots in order to ...
