El estudio tuvo como objetivo evaluar los parámetros cinéticos de la degradación in situ de la materia seca (MS), proteína cruda (PC) y la estimación del consumo mediante ecuaciones de predicción de MS de forrajes y alimentos concentrados en alpacas Huacaya (Vicugna pacos). Se trabajó con ensilado de maíz chala (Zea mays L) sin y con 1% de urea, cebada (Hordeum vulgare L), avena (Avena sativa L), salvado de trigo (Triticum aestivum L) y raspa de papa (Solanum tuberosum). Los alimentos (5 g en base seca) fueron colocados en sacos de nylon e incubados en el primer compartimento estomacal de dos alpacas fistuladas durante 0, 6, 12, 24, 48 y 76 horas. Se analizó la MS y la PC de los residuos de los sacos. La MS y la PC del salvado de trigo y de la raspa de papa presentaron potenciales de degradación elevados, así como la MS y la PC de la avena. Se destaca la mayor fracción no degradable de la PC del maíz chala sin y con urea y, por tanto, una menor degradabilidad de la PC. Las estimaciones del consumo por las alpacas generadas por las ecuaciones de tres estudios no son adecuadas a los alimentos en estudio.

A pathogen transmitted by the eriophyid mite, Aceria tulipae, infects a number of Gramineae producing symptoms similar to wheat spot mosaic virus (1). An electron microscope study of leaf ultrastructure from systemically infected Zea mays, Hordeum vulgare, and Triticum aestivum showed the presence of ovoid, double membrane bodies (0.1 - 0.2 microns) in the cytoplasm of parenchyma, phloem and epidermis cells (Fig. 1 ).

Entre las enfermedades que afectan al cultivo de maíz (Zea mays) en Argentina, la producida por el virus del mal de Río Cuarto (MRCV) es la más importante. El MRCV pertenece a la familia Reoviridae, género Fijivirus, y su propagación en la naturaleza es realizada por Delphacodes kuscheli (Hemiptera: Delphacidae). La modalidad de transmisión para los miembros de este género de virus es persistente propagativa. Se estableció la necesidad de ajustar un sistema de transmisión eficiente del virus para estudios de caracterización, partiendo de poblaciones libres de virus criadas en laboratorio, para lo cual se ensayaron distintos períodos de adquisición, latencia e inoculación, evaluándose además un rango de hospedantes diferenciales. Se lograron obtener insectos libres de virus en cantidad suficiente para llevar a cabo los trabajos, mediante su cría en fitotrones y cámaras aclimatadas. La transmisión experimental del MRCV se efectuó exitosamente, bajo idénticas condiciones, empleando períodos de adquisición, latencia e inoculación de dos, 10 y uno día respectivamente para los cereales de grano fino y de dos, 10 y dos días para el maíz. Se infectaron de este modo las siguientes especies: maíz, cebada (Hordeum vulgare), avena (Avena sativa), trigo (Triticum aestivum), centeno (Secale cereale), grama rhodes (Chloris gayana) y alpiste (Phalaris canariensis). La detección del virus en las plantas inoculadas se efectuó mediante pruebas serológicas, análisis de dsRNA en electroforesis en gel de poliacrilamida (obteniéndose las 10 bandas típicas de los fijivirus) y microscopía electrónica, detectándose las partículas isométricas de entre 60 y 70 nm de diámetro.

The vacuolar H+-ATPase (V-ATPase) plays many important roles in cell growth and in response to stresses in plants. The V-ATPase subunit H (VHA-H) is required to form a stable and active V-ATPase. Genome-wide analyses of VHA-H genes in crops contribute significantly to a systematic understanding of their functions. A total of 22 VHA-H genes were identified from 11 plants representing major crops including cotton, rice, millet, sorghum, rapeseed, maize, wheat, soybean, barley, potato, and beet. All of these VHA-H genes shared exon-intron structures similar to those of Arabidopsis thaliana. The C-terminal domain of VHA-H was shorter and more conserved than the N-terminal domain. The VHA-H gene was effectively used as a genetic marker to infer the phylogenetic relationships among plants, which were congruent with currently accepted taxonomic groupings. The VHA-H genes from six species of crops (Gossypium raimondii, Brassica napus, Glycine max, Solanum tuberosum, Triticum aestivum, and Zea mays) showed high gene structural diversity. This resulted from the gains and losses of introns. Seven VHA-H genes in six species of crops (Gossypium raimondii, Hordeum vulgare, Solanum tuberosum, Setaria italica, Triticum aestivum, and Zea mays) contained multiple transcript isoforms arising from alternative splicing. The study of cis-acting elements of gene promoters and RNA-seq gene expression patterns confirms the role of VHA-H genes as eco-enzymes. The gene structural diversity and proteomic diversity of VHA-H genes in our crop sampling facilitate understanding of their functional diversity, including stress responses and traits important for crop improvement.

2,4 Dichlorophenoxyacetic Acid

In the greenhouse, five crops were grown in soil containing trichloroacetic acid (TCA) at 3 to 24 ppm. Based on seedling yields, corn (Zea mays L., var. Morden 88) and oats (Avena sativa L., var. Rodney) were relatively tolerant to TCA at all rates, barley (Hordeum vulgare L., var. Conquest) and rye (Secale cereale L., var. Antelope) were tolerant at lower rates, but wheat (Triticum aestivum L., var. Manitou) suffered injury at all rates. When TCA-2-14C was applied to the roots of wheat and oats seedlings in water or nutrient solution, wheat seedlings absorbed more TCA-2-14C than oats. Potassium cyanide (KCN) and 2,4-dichlorophenoxyacetic acid (2,4-D) decreased TCA-2-14C absorption by wheat more than that by oats. From 5 to 21 days after application, wheat retained two to four times as much TCA-2-14C as oats. Thus, half of the TCA-2-14C in shoots and roots of wheat disappeared in 11.3 and 11.4 days, respectively, compared with 7.9 and 3.5 days for oats. Based on this investigation, the difference in susceptibility of wheat and oats to TCA appeared to be governed by the metabolic processes involved in absorption and dissipation.

Tolerance of sugarbeets (Beta vulgaris L. ‘Mono-Hy A1’) to ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulphonate) was associated with rate of application and soil type. Yield of roots was significantly reduced by preplant-incorporated applications of 3.4, 4.5, or 9.0 kg/ha of ethofumesate to a sandy loam soil, but only the 9.0 kg/ha rate reduced the yield on a loam soil. Pinto beans (Phaseolus vulgaris L. ‘Idaho #111’) yielded normally when planted on a sandy loam soil within 4 to 6 weeks after ethofumesate was incorporated at rates of 2.2 to 9.0 kg/ha. Corn [Zea mays L. ‘Pioneer brand 3773 MFS(N) hybrid’] yields were reduced in proportion to the rate of herbicide applied 3 weeks before planting. In greenhouse studies, barley (Hordeum vulgare L. ‘Moravian’) and wheat (Triticum aestivum L. ‘Scout’) were about 10 times more susceptible to soil residues of ethofumesate than corn. Concentrations of ethofumesate in the soil as low as 0.1, 0.2, and 1.5 ppmw reduced the height of wheat, barley, and corn, respectively.
