Background The heterologous expression of isopentenyl transferase (IPT) under the transcriptional control of the senescence-associated receptor-like kinase (SARK) promoter delayed cellular senescence and, through it, increased drought tolerance in plants. To evaluate the effect of pSARK::IPT expression in bread wheat, six independent transgenic eve...

La roya amarilla (RA) de los cereales provocada por el hongo Puccinia striiformis Westend. sensu lato (sentido amplio); este hongo se puede dividir en cinco formas especiales (f. sp.) agropyri, elymi, hordei, secalis y tritici, asociadas al hospedante que infectan con mayor frecuencia. En la campaña 2020/21 en ensayos comparativos de rendimiento de...

Las enfermedades fúngicas causan pérdidas de rendimiento y de calidad en los granos de cebada, especialmente en las cebadas con destino a maltería. Existe un número acotado de variedades de cebada, las cuales en mayor o menor medida son susceptibles a alguna de las principales enfermedades que afectan a este cultivo (Moreyra y col., 2020). En el co...

Somatic embryogenesis, which is still the method of choice for tissue culture, regeneration and transformation of maize, is largely considered highly genotype-dependent. The Hi II, a highly embryogenic genotype, has been extensively used in transformation protocols. However, this is not an inbred line; instead, it has a proportion of the undesirabl...

Maize (Zea mays) is one of the main food crops worldwide, with a global production of 5.856.396 tons and 159.531.007 Ha. harvested in 2009/2010. Due to the importance of maize production is necessary to improve the yields using biotechnological tools. Plant transformation techniques are essential for the introduction of novel useful traits occurrin...

Two decades have passed since the first maize transformation protocol. Genetic breeding has been decisive and essential to transform maize a major food crop worldwide. Biotechnology plays an important role in plant genetic breeding, particularly for the introduction of novel traits in order to improve agronomic performance, medical and industrial a...

Maize (Zea mays) is a major food crop of the world. Biotechnology plays an important role in plant genetic improvement, particularly for the introduction of novel traits in order to improve agronomic performance, medical and industrial applications and food quality. Particle bombardment is a rapid and simple method that enables the generation of ev...

... In all these cases, crops yield better than the comparator under abiotic stress. In some cases, the modified plants yield better than controls even in the absence of stress (Beznec et al., 2021;Esmaeili et al., 2021;Yu et al., 2021;Sprague et al., 2022). Examples likely requiring an RSR are included in Table 2 representing 27 cases from banana (Sreedharan et al., 2013), barley (Hughes et al., 2017), canola , corn (Shi et al., 2017;Nuccio et al., 2015), cotton (Mishra et al. 2017), poplar (Li et al., 2018b), potato (Yu et al., 2021), rice (Shim et al., 2018;El-Esawi and Alayafi 2019;Liu et al. 2020b;Caine et al., 2019;Zhang et al., 2018a;Jiang et al., 2019;Park et al., 2020;Joshi et al., 2019;Selvaraj et al. 2017;Selvaraj et al., 2020, Usman et al., 2020a, soybean (Ribichich et al., 2020), tobacco (Sharma et al., 2019), tomato , and (2), cotton (2), rice (7), potato, wheat (2) 1, 2, 13, 15 ...
... Until now, miRNAs have been studied more in the context of in vitro cultures rather than the phenomenon of variability. In vitro culture conditions such as culture medium, photoperiod or phytohormone ratio can be adjusted to promote somatic embryogenesis or organogenesis from induced callus [15]. The molecular pathway of shoot regeneration primarily includes phytohormones and genes related to shoot apical meristem [16]. ...
... Maize embryogenic type II calluses (Décima Oneto et al., 2011) were initiated from immature embryos of the Hi-II genotype (Gordon-Kamm et al., 2002). Immature embryos were aseptically isolated from Hi-II seeds, 10 to 12 days post pollination. ...
... Microprojectile bombardment was reported to be the most suitable techniques for maize transformation [25,26]. Protocol improvement for maize transformation to increase the maize transformation efficiency and regeneration was performed [27]. It is important to highlight that transgenic maize tools has developed an important techniques to improve food and agronomic quality [28]. ...
... More expericed farmers have an opportunity to create a relationship with the lenders than new or their counterparts. This finding is consistence with the study of (Oneto et al., 2010;Ray, 2020). Our result indicated that family size and credit access have a positive and statistically significant effect in increasing the agricultural access credit of the households. ...
