Abstract:
... Tecomella undulata (Sm.) Seem (family Bignoniaceae) is an economically and pharmaceutically important timber tree of arid regions of India. Overexploitation of natural stands coupled with minimal conservation and reforestation efforts has led to its incorporation in list of endangered species. This monotypic genus can be propagated only through seeds as no methods are available for its vegetative ...

Abstract:
... The fine-scale genetic structure and how it varies between generations depends on the spatial scale of gene dispersal and other fundamental aspects of species’ biology, such as the mating system. Such knowledge is crucial for the design of genetic conservation strategies. This is particularly relevant for species that are increasingly fragmented such as Boswellia papyrifera. This species occurs in ...

Abstract:
... Well-feathered apple trees are essential for commercial orchards to optimize yields. However, most cultivars do not form these sylleptic branches readily in commercial nurseries due to high apical dominance. Several treatments exist to promote their formation in the nurseries, one of which is heading. However, not all cultivars are expected to react similarly to these treatments. We studied the br ...

Although a genome-wide analysis of NPR1 gene family has been conducted in some plant species, little is known about these genes in apple (Malus spp.). In this study, eight NPR1 homologs were identified within the apple genome ...

Abstract:
... Fragmented populations at the edges of a species’ distribution can be highly exposed to the loss of genetic variation, unless sufficient gene flow maintains their genetic connectivity. Gene movements leading to successful establishment of external gametes (i.e. effective gene flow) into fragmented populations can solely be assessed by investigating the origin of natural regeneration. This study is ...
