“…The surfaces of different floral organs host diverse communities of bacteria [ 2 ]. Culture-dependent and independent studies have described bacteria in nectar [ 189 , 190 , 191 , 192 ], petals [ 58 , 192 ], pistil [ 58 , 193 ], and as mentioned previously, in pollen [ 95 , 96 ] and fruit [ 64 , 132 , 194 ]. The bacteria that colonize flower surfaces can originate from the same sources as the bacteria that colonize leaf surfaces (i.e., air, dust, wind, rain splash, and surrounding plants and soil, or from pollinators and other insect visiting flowers [ 195 ]).…”

Transmission of Bacterial Endophytes

Plants are hosts to complex communities of endophytic bacteria that colonize the interior of both below- and aboveground tissues. Bacteria living inside plant tissues as endophytes can be horizontally acquired from the environment with each new generation, or vertically transmitted from generation to generation via seed. A better understanding of bacterial endophyte transmission routes and modes will benefit studies of plant–endophyte interactions in both agricultural and natural ecosystems. In this review, we provide an overview of the transmission routes that bacteria can take to colonize plants, including vertically via seeds and pollen, and horizontally via soil, atmosphere, and insects. We discuss both well-documented and understudied transmission routes, and identify gaps in our knowledge on how bacteria reach the inside of plants. Where little knowledge is available on endophytes, we draw from studies on bacterial plant pathogens to discuss potential transmission routes. Colonization of roots from soil is the best studied transmission route, and probably the most important, although more studies of transmission to aerial parts and stomatal colonization are needed, as are studies that conclusively confirm vertical transfer. While vertical transfer of bacterial endophytes likely occurs, obligate and strictly vertically transferred symbioses with bacteria are probably unusual in plants. Instead, plants appear to benefit from the ability to respond to a changing environment by acquiring its endophytic microbiome anew with each generation, and over the lifetime of individuals.

The antimicrobial effect of eight essential oils’ vapors against pathogens and spoilage bacteria was assayed. Oreganum vulgare L. essential oil (OVO) showed a broad antibacterial effect, with Minimum Inhibitory Concentration (MIC) values ranging from 94 to 754 µg cm−3 air, depending on the bacterial species. Then, gaseous OVO was used for the treatment of stainless steel, polypropylene, and glass surfaces contaminated with four bacterial pathogens at 6–7 log cfu coupon−1. No viable cells were found after OVO treatment on all food-contact surfaces contaminated with all pathogens, with the exception of Sta. aureus DSM 799 on the glass surface. The antimicrobial activity of OVO after the addition of beef extract as a soiling agent reduced the Sta. aureus DSM 799 viable cell count by more than 5 log cfu coupon−1 on polypropylene and glass, while no viable cells were found in the case of stainless steel. HS-GC-MS analysis of the headspace of the boxes used for the antibacterial assay revealed 14 different volatile compounds with α-Pinene (62–63%), and p-Cymene (21%) as the main terpenes. In conclusion, gaseous OVO could be used for the microbial decontamination of food-contact surfaces, although its efficacy needs to be evaluated since it depends on several parameters such as target microorganisms, food-contact material, temperature, time of contact, and relative humidity.

“…Zucchini flowers Cucurbita pepo L. and pumpkins ( Cucurbita spp.) are also edible flowers that are a part of the Mediterranean diet (Baruzzi et al., 2012; Villalta et al., 2004). They can be found at specialty farmer markets, spice stores, gourmet markets, or freshly picked from home gardens, and are used in salads, dressings, soups and main dishes, however, they are most commonly used in quesadillas (corn or wheat tortillas filled with melted cheese and squash flowers), in pasta in Italian cuisine, and in crepes in French cuisine (Aquino‐Bolanos et al., 2013).…”

Contribution of edible flowers to the Mediterranean diet: Phytonutrients, bioactivity evaluation and applications

et al. 2022

The Mediterranean diet is acknowledged to be the healthiest dietary pattern around the world, mainly based on plant foods from the rich Mediterranean flora. It is also known to increase longevity and have positive effects on chronic diseases. This review aimed to investigate the knowledge about the use and consumption of edible flowers as part of the Mediterranean cuisine, based on ethnobotanical and ethnopharmacological studies especially from the last 10 years, and highlight their uses as a nutritious and functional food. In this review, a total of 32 edible flower species used in the Mediterranean diet were listed with their phytochemical composition, edible applications, bioactive properties, and dose, highlighting their nutritional contribution to the Mediterranean diet as well as their health effects. Edible flowers are consumed and widely contribute to the health-promoting properties of the Mediterranean diet through being good sources of macro and micronutrients that enhance the nutritive value of Mediterranean dishes and foods, as well as providing more phytonutrients. Based on this, Mediterranean dishes have the remarkable characteristics of being conducive to mitochondrial health and anti-metabolic diseases. The functional components in edible flowers are clarified here, which might be considered as a new factor for rational diet, natural product development, and medical improvement.
