In most plant species, initiation of lateral roots occurs above the elongation zone. However, in Cucurbitaceae it takes place in the parental root meristem. Ilina et
News in Brief
Plants brought in by gardeners for horticultural reasons can turn invasive. Research published by an international team from the US, Europe and China finds that climate change could increase the competitiveness of non-naturalized species.
