“…These TFs (RISBZ1, RISBZ4, and RISBZ5) were isolated from a rice seed cDNA library and it was demonstrated that they activate the synthesis of such storage proteins [35]. A Dof TF, OBP3, was patented in 2007 as a tool to increase the size of the transgenic plant in which it is inserted in a given construct [27].…”

Transcription factors are clue elements in the regulation of signal transduction pathways in living organisms. These proteins are able to recognize and bind specific sequences in the promoter regions of their targets and subsequently activate or repress entire metabolic or developmental processes. About 1500 TFs were informatically identified in plants, analysis mainly based in the presence of DNA-binding domains in the translated sequences. However, only a few of these 1500 were functionally characterized and clearly classified as TFs. Among these, several seem to be powerful biotechnological tools in order to improve agronomic crops via the obtaining of transgenic plants or as molecular markers. Such TFs have become the objects of patents presentations in the whole world. The assigned uses present a variety of purposes including the improvement in yield, abiotic and biotic stresses tolerances as well as a combination of them. Some examples are commented in the present overview. Most of these TFs confer to transgenic plants complex phenotypes due to a combination of different regulated pathways. In this sense, the use of inducible promoters instead of constitutive ones seems in some cases to be useful to limit the changed phenotype to the desired one, avoiding lateral effects. None of these TFs was converted up to now in a market product since time-consuming experiments and regulation permits are required to arrive to such point. Moreover, a considerable money investment must be done, not justified in all cases. However, it is likely that these molecules will become in the near future the first choice for breeders since it was demonstrated that TFs are very efficient conferring desired traits to transgenic plants. Additionally, for the public perception the over or ectopic expression of a plant gene should be more accepted than the use of molecules from other species.

“…Even before the COVID-19 pandemic, many food system workers experienced challenges atypical of other “essential” sectors. Many of these challenges are associated with negative outcomes (Fan & Qian, 2017; Neff, 2015; Williams et al, 2019), including presenteeism (Webster et al, 2019). The many food system workers who come from marginalized and foreign-born communities (Fan & Qian, 2017; Stephenson, 2020) face high rates of systemic and individual discrimination (Menasche Horowitz et al, 2019) including in the workplace (Siqueira et al, 2014).…”

BackgroundAs “stay at home” orders were in effect, many US food workers attended in-person work during early phases of the COVID-19 pandemic, charged with maintaining normal operation of the national food supply chain. Despite establishment of a novel national paid sick leave policy, anecdotal evidence suggests that many U.S. food system workers encountered barriers to staying home when ill.MethodsUsing quantitative and free-text analyses from a national, cross-sectional, online survey deployed from July to October 2020 among 2,535 respondents, we explored workplace and non-workplace factors associated with U.S. food system workers’ intentions to attend work while ill (i.e. presenteeism intentions) during the first four to six months of the COVID-19 pandemic.ResultsOverall, 8.8% of workers surveyed reported intentions to attend work while ill. Both quantitative data and free-text responses suggest that aspects of workplace culture influenced workers’ decisions to attend work while ill. Workers reporting a high workplace safety climate score had half the odds of reporting presenteeism intentions (adjusted odds ratio [aOR] 0.52, 95% confidence interval (CI) 0.37, 0.75) relative to those reporting low scores. Workers described cultural barriers, including retaliation and penalties, that reduced paid sick leave access. Workers reporting low (aOR 2.06, 95% CI 1.35, 3.13) or very low (aOR 2.31, 95% CI 1.50, 3.13) levels of household food security had more than twice the odds of reporting presenteeism intentions.ConclusionsThis study offers insights into opportunities for reducing presenteeism related to illness among food workers both during the COVID-19 pandemic and in other infectious disease scenarios. Addressing vulnerabilities like food insecurity and empowering food system workers to make health-protective decisions is important both for optimal worker health outcomes and maintaining a functioning food system.

“…[2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] More than 50 years have passed since Haszeldine reported the first addition of a trifluoromethyl radical to an allene, 17 yet there continues to be great interest in both the mechanistic aspects and the synthetic applications of radical reactions involving allenes. 18 This is due in part to the expanding diversity and ease of new methods to synthesize increasingly complex allenes [19][20][21][22][23][24] as well as ongoing reports of applications that harness the unique reactivity of allenes as compared to alkenes and alkynes. 9,10,13,14 Because of their structural differences and unique bonding properties, the reactivities of allenes toward different types of radicals is less predictable than the trends observed in reactions with alkenes and alkynes.…”

Mechanistic Aspects and Synthetic Applications of Radical Additions to Allenes

More than 50 years have passed since Haszeldine reported the first addition of a trifluoromethyl radical to an allene; in the intervening years, both the chemistry of allenes and the reactivity of single-electron species have become topics of intense interest. In this Review, we provide an overview of the fundamentals of radical additions to allenes and highlight the emergence of theoretical and experimental evidence that reveals unique reactivity patterns for radical additions to allenes as compared with other unsaturated compounds. Factors capable of exerting control over the chemo-, regio-, and stereoselectivities of the attack of carbon-and heteroatom-based radicals at each of the three potential reactive sites in an allene substrate are described. These include reaction conditions, the nature of the attacking radical, the substitution pattern of the allene, and the length of the linker between the radical center and the proximal allene carbon in the substrate. Cycloaddition reactions between allenes and partners containing π-bonds, which are likely to proceed through radical pathways, are presented to highlight their ability to rapidly access complex polycyclic scaffolds. Finally, the synthetic utility of the products arising from these chemistries is described, including their applications to the construction of complex molecules.
