Aegilops tauschii (Ae. tauschii) is a diploid (2n = 2x = 14) wild grass species, which has been reported as the progenitor of hexaploid wheat (Triticum aestivum) with D-genome. In this study, 68 Ae. tauschii accessions with diverse geographical backgrounds were investigated for their resistance to infection by the leaf rust fungi Puccinia triticina. Two Ae. tauschii accessions that exhibited hyper-resistance to leaf rust at both seedling and adult stages were identified. Utilizing two susceptible Ae. tauschii ecotypes and keumkang, a common Korean wheat cultivar known to be susceptible to leaf rust, as the negative control, further investigations were conducted for understanding the mechanism underlying immunity to leaf rust disease of these two resistant accessions. Resistant accessions displayed the increased β-1,3-glucanase activity to prevent fungal penetration and the better peroxidase activity to cope with leaf rustinduced oxidative stress. Moreover, transcriptional analyses reveal the important role of the LRR receptor-like serine/ threonine-protein kinase FLS2 (lrr) to the disease resistance of the two ecotypes. Ae. tauschii is a remarkable genetic source, especially for abiotic and biotic stress resistance genes, as the plant is known for its wide-ranging geographical habitat and adaptability to different environments. This, combined with the fact that Ae. tauschii and wheat share a close evolutionary relationship, is indicative of the immense benefit of using Ae. tauschii as a material for improving the quality of synthetic wheat. Our aim was to identify and evaluate the strongest Ae. tauschii contenders for breeding leaf rust-resistant synthetic wheat.

“…These genes are likely involved in anti-viral defense responses triggered after BSMV inoculation. Induction of different functional classes of 'pathogenesis-related proteins' after virus infection has previously been demonstrated (Bol et al 1990;Sudisha et al 2012); this finding is therefore not surprising. Importantly, these genes were downregulated (with respect to the 'empty virus' control) when A K249842 expression was reduced through gene-specific VIGS.…”

Pattern recognition receptors represent a first line of plant defense against pathogens. Comparing the flag leaf transcriptomes of barley (Hordeum vulgare L.) near-isogenic lines varying in the allelic state of a locus controlling senescence, we have previously identified a leucine-rich repeat receptor-like protein kinase gene (LRR-RLK; GenBank accession: AK249842), which was strongly upregulated in leaves of early-as compared to late-senescing germplasm. Bioinformatic analysis indicated that this gene codes for a subfamily XII, non-arginine-aspartate (non-RD) LRR-RLK. Virus-induced gene silencing resulted in a two-fold reduction of transcript levels as compared to controls. Transcriptomic comparison of leaves from untreated plants, from plants treated with virus only without any plant sequences (referred to as 'empty virus' control), and from plants in which AK249842 expression was knocked down identified numerous genes involved in pathogen defense. These genes were strongly induced in 'empty virus' as compared to untreated controls, but their expression was significantly reduced (again compared to 'empty virus' controls) when AK249842 was knocked down, indicating that their expression partially depends on the LRR-RLK investigated here. Expression analysis, using datasets from BarleyBase/PLEXdb, demonstrated that AK249842 transcript levels are heavily influenced by the allelic state of the well-characterized mildew resistance a (Mla) locus, and that the gene is induced after powdery mildew and stem rust infection. Together, our data suggest that AK249842 is a barley pattern recognition receptor with a tentative role in defense against fungal pathogens, setting the stage for its full functional characterization.

“…La distancia entrenudos es un indicador que facilita la recolección de las hojas, sobre todo cuando éstas son colectadas en mancuernas, cuando éste es cultivado en la forma sol en palo, porque beneficia el corte manual con la menor ocurrencia de daños mecánicos. Estos resultados corroboran lo planteado por Farouk & Amany (2012) y Sudisha et al (2012) quiénes consideraron que los bioestimulantes actualmente son utilizados como biorreguladores del desarrollo de las plantas, pues pueden regular la síntesis y acción de las hormonas y distintos procesos de organogénesis y crecimiento y de manera directa y específica regulan muchos de los procesos fisiológicos que se traducen en la formación de órganos en las plantas. En este sentido, Martínez con diferencias significativas con las aplicaciones individuales de ME-50 y BB-16 e incrementar los valores promedio de este indicador en 28.01 % a los 21 ddt (Figura 2(A)), 28.06 % a los 42 ddt (Figura 2(B)) y de 11.32 % 64 ddt (Figura 2(C)).…”

Artículo Investigación RESUMEN: Con el objetivo de evaluar el efecto de dos bioestimulantes en el comportamiento agrícola del cultivo del tabaco negro 'Sancti Spíritus 2006', se desarrolló un experimento en la Cooperativa de Créditos y Servicios "Sindulfo García", Sancti Spíritus, Cuba, de octubre a diciembre de 2015. Se evaluaron los siguientes tratamientos: control, inoculación al suelo y aplicación foliar de ME-50 a 100 mg L −1 , aplicación foliar de Biobras-16 R a 0.05 mg L −1 y la combinación de ambos. Las principales observaciones correspondieron a las siguientes variables morfoagronómicas: distancia entre nudos (cm), largo y ancho de las hojas centrales (cm), altura de las plantas (cm) y el número de hojas por planta. Los resultados mostraron que la aplicación de los bioestimulantes ME-50, Biobras-16 R , así como su combinación incrementaron las variables morfológicas en la variedad de tabaco negro 'Sancti Spíritus 2006'. Los mayores resultados fueron logrados con la aplicación combinada de los dos bioestimulantes porque incrementaron los indicadores observados comparada con la utilización individual de ME-50 y BB-16 e incrementó el número de hojas por planta en relación al tratamiento control en 35.51 % a los 64 ddt.ABSTRACT: With the objective of to evaluate the effect of two biostimulants on the agricultural behavior of the black tobacco crop 'Sancti Spíritus 2006' was developed an experiment in the collective framer "Sindulfo García", Sancti Spíritus, Cuba, from october to december 2015. The following treatments were evaluated: control, inoculation and foliar application of ME-50 at 100 mg L −1 , foliar application of Biobras-16 R at 0.05 mg L −1 and the combination of both.
