“…Foliar surface features serve as protectors against water loss, herbivores, herbicides and other biotic and abiotic stress factors (Domínguez et al, 2017). Our previous results strongly indicated differences in the herbicide response between young and mature plants (Figure 1; Abu‐Nassar & Matzrafi, 2021). Using herbicides with different modes of action [i.e.…”

“…Our previous study strongly indicated differences in herbicide response between young and mature plants and with or without the addition of surfactant to the spraying mix (Abu‐Nassar & Matzrafi, 2021). Surfactants are unique molecules in that they maintain lipophilic and hydrophilic balance for the spraying solution.…”

“…rostratum was first documented in the Jezreel Valley in 1953 (Danin, 2021). Since then, several field populations have been located in the Jordan Valley, the Golan Heights, the Hula Valley and along the Mediterranean Sea coastline (Abu‐Nassar & Matzrafi, 2021). Solanum rostratum has high drought resilience and it is an extremely aggressive weed; after seed ripening, berries dry and are cracked open, the main stem breaks near the ground and the plant rolls, scattering thousands of seeds (Wei et al, 2010).…”

“…rostratum's growth stage had a significant effect on herbicide activity (Abu‐Nassar & Matzrafi, 2021). While plants were adequately controlled by different herbicides during the early growth stage, at late growth stages, overall herbicide efficacy was lower (Figure 1; Abu‐Nassar & Matzrafi, 2021). Here, we aimed to investigate leaf structural properties in young and mature leaves of S .…”

Solanum rostratum Dunal is an aggressive invasive weed invading many countries worldwide. Our previous study indicated differences in herbicide response between young and mature plants. In this study, we explore the functional leaf surface anatomy of S. rostratum. Leaf area surface characterisation was performed by counting stomata, stellate and glandular trichomes on upper and lower leaf sides on scanning electron microscopy (SEM) micrographs. Total cuticular waxes were extracted and weighed in young and mature leaves. Young and mature leaves were tested for water permeability of the epidermal surfaces using the apoplastic tracer Calcofluor. S. rostratum plants were sprayed with luminous trace colour solution with and without 1% surfactant, droplet number and area were calculated. In young S. rostratum leaves, the leaf surface was densely covered with stellate trichomes on both leaf sides; however, in the mature leaf, stellate trichomes density became low, and prickle rigid increased in mature leaves. Wax amount was significantly higher in mature leaves, while number of stomata was higher in young leaves. Young leaves showed high leaf permeability, with the fluorescent dye permeating the leaf staining the vascular bundles. In young and mature leaves treated with a spraying solution with the addition of surfactant, low droplet number alongside higher coverage area was recorded. Our data highlight the notable differences in leaf epidermal structure of young versus mature plants. We conclude that differences in herbicide permeability, water loss and herbivory in young versus mature leaves of S. rostratum are governed by variation in leaf functional anatomy.

“…Genomic comparisons between the invasive population in Israel and native North American wild sunflower populations indicated that its origin is in the southwest USA, from where it was presumably introduced with imported agricultural products. Previous studies on other invasive species in Israel suggested southwest USA as a source of the invading population (Abu‐Nassar & Matzrafi, 2021; Yair et al, 2017). Southwest USA, and specifically Texas, is located on the same latitude as Israel (31°N) and shares some of the climatic conditions, although both regions are characterized by a wide spectrum of environmental conditions.…”

Globalization and intensified volume of trade and transport around the world are accelerating the rate of biological invasions. It is therefore increasingly important to understand the processes through which invasive species colonize new habitats, often to the detriment of native flora. The initial steps of an invasion are particularly critical, as the introduced species relies on limited genetic diversity to adapt to a new environment. However, our understanding of this critical stage of the invasion is currently limited. We used a citizen science approach and social media to survey the distribution of invasive sunflower in Israel. We then sampled and sequenced a representative collection and compared it with available genomic data sets of North American wild sunflower, landraces and cultivars. We show that invasive wild sunflower is rapidly establishing throughout Israel, probably from a single, recent introduction from Texas, while maintaining high genetic diversity through ongoing gene flow. Since its introduction, invasive sunflower has spread quickly to most regions, and differentiation was detected despite extensive gene flow between clusters. Our findings suggest that rapid spread followed by continuous gene flow between diverging populations can serve as an efficient mechanism for maintaining sufficient genetic diversity at the early stages of invasion, promoting rapid adaptation and establishment in the new territory.
