“…The smaller fruit is Cucumis myriocarpus (prickly paddy melon), which has an average diameter of 2–3 cm. The fruit of Citullus colocynthis (colocynth melon) is similar in size and appearance to that of C. lanatus , but C. colocynthis rind tends to have a mottled or mosaic pattern as opposed to the spotted or striped pattern seen on C. lanatus ( Shaik et al ., 2012 ). …”

“…The perennial species, C. colocynthis , is closely related, shares morphological similarity with C. lanatus and is often misidentified even on fruit formation. Interestingly, initial trials with chloroplastidic mat K gene did not result in separation of these two congeneric species because their sequences were 100% similar ( Shaik et al ., 2011 ). However, a chloroplast gene ( ycf 6- psb M) and a nuclear gene ( G3pdh intron region) based on Dane et al .…”

Understanding invasion history and predicting invasive niches using genetic sequencing technology in Australia: case studies from Cucurbitaceae and Boraginaceae

The development of genetic profiles of invading plants can provide insight towards a better understanding of niche utilization. Recent advances in sequencing techniques have greatly facilitated genetic assessment and profiling. Here we review our recent studies on selected Australian Cucurbitaceae and Boraginaceae to demonstrate the application of genetic sequencing across a selection of invasive Australian plants.

“…In pesticides, lead chemical compounds are technically referred to as active ingredients, with Nemarioc-AL and Nemafric-BL phytonematicides being cucurbitacin A (C 32 H 48 O 9 ) and cucurbitacin B (C 32 H 48 O 8 ), respectively [7]. The two products, produced from two different Cucumis species, with centers of biodiversity in South Africa [8], had since attained cosmopolitan status as invasive plant species [9]. Conventional synthetic chemical nematicides had been withdrawn from the agrochemical markets due to their widespread drawbacks, which included environment-a1111111111 a1111111111 a1111111111 a1111111111 a1111111111 unfriendly and sustainability issues [8].…”

Shelf-life information provides end-users with the assurance that the product is still in compliance with label claims. Behavioral reaction orders of the Arrhenius model had been consistently used under fixed conditions to provide shelf-life in food products. Due to nonconformity of the cucurbitacin-containing phytonematicides to the Arrhenius behavioral reaction orders, an alternative quadratic model consistent with the behavioral reaction orders of cucurbitacins was developed under chilled (5˚C at 95-98% RH) and fixed tropical (38˚C at 90% RH) conditions, while room temperature constituted unfixed conditions. Sampling for cucurbitacins was done at time-frames compliant with geometric series, with cucurbitacin analysis regularly performed using high-performance liquid chromatography techniques. Under chilled conditions, neither the Arrhenius nor the quadratic model could predict the shelf-life for Nemarioc-AL phytonematicide, whereas Nemafric-BL phytonematicide had shelf-life of 35 weeks. In contrast, under tropical conditions, the positive quadratic models showed that Nemarioc-AL and Nemafric-BL phytonematicides had shelf-life of 35 and 825 weeks, respectively. In conclusion, the two phytonematicides could be stored under fixed tropical conditions to enhance the shelf-life of their active ingredients.

“…Weeds and invasive plant species negatively impact agriculture worldwide. They compete with crop plants for water, nutrients, and light, interfering with crop growth, and can ultimately reduce yields (for reviews, see refs – ). Weeds can be controlled by a variety of means including mechanical, chemical, and biological methods.…”

Activity of Icacinol from Icacina trichantha on Seedling Growth of Oryza sativa and Arabidopsis thaliana

et al. 2017

Broadleaf weeds are very costly for crop growers. Additional herbicidal compounds need to be obtained, especially from natural sources. Extracts of Icacina trichantha were evaluated for responses in germinating seeds and seedlings of rice (Oryza sativa) and Arabidopsis (Arabidopsis thaliana). An ethyl acetate fraction of I. trichantha tuber and a diterpenoid constituent, icacinol (1), were found to have impacts on germination and growth of seedlings. The seed germination inhibitory activity on rice was minimal, but significant on Arabidopsis. While rice indicated some growth delay in leaf expansion in the presence of 1, the effects appeared temporary; chlorophyll and anthocyanins were not significantly altered compared to DMSO controls. Rice seedlings attained biomass similar to DMSO controls, and rice grains per panicle were not significantly different from the DMSO controls. On the other hand, Arabidopsis exhibited damage to leaf expansion, reduced chlorophyll, and increased anthocyanins in aerial portions of the seedlings. Icacinol (1) may be a suitable chemical agent to investigate further for the treatment of eudicot weeds.
