O presente estudo foi conduzido objetivando-se medir o estresse climático de ovinos das raças Morada Nova e Santa Inês, criados em condições semi-intensiva, na região semiárida do Nordeste através de medidas das frequências respiratórias e cardíacas. Foram utilizados 10 animais de cada raça, e as mensurações das freqüências respiratórias e cardíacas, efetuadas em cinco dias consecutivos nos turnos da manhã e tarde durante o período chuvoso. Os animais Morada Nova apresentaram menores freqüências respiratórias (44,23 mov/min) e, maiores frequências cardíacas (77,04 bat/min) do que os da raça Santa Inês (51,37 mov/min; 72,02 bat/min,), respectivamente, que mostraram-se mais sensíveis ao estresse ambiental, uma vez que as frequências respiratórias foram maiores. Os animais da raça Morada Nova mostraram-se menos sensíveis ao estresse ambiental do que os ovinos Santa Inês, nas condições climáticas estudadas. Evaluation of breathing and heart frequency in sheep of different breeds. Abstract: The aimed of this study to measure the environmental stress of sheep breeds Morada Nova and Santa Ines, created under in the semi-intensive, in region semiarid Northeastern through the measurement of breathing frequency and heart frequency. Ten animals of each breed, and the measurements breathing and heart frequency made on five days consecutive in the shifts the morning and afternoon during the rainy season. The animals Morada Nova had lower breathing frequency (44.23 mov/min) and higher heart frequency (77.04 beats/min) than the Santa Ines (51.37 mov/min; 72.02 beats/min), respectively, which were more sensitive to environmental stress, since the breathing frequency were higher. The animals Morada Nova were less sensitive to environmental stress than sheep Santa Ines in the environment conditions studied.

This work aimed to evaluate the drought tolerance of transformed plants of the cultivar BRSMG Curinga that overexpress the rice phospholipase D &1(OsPLD&1) gene. The productivity of independent transformation event plants of the OsPLD&1 gene was evaluated in an experiment where 19 days of water deficit were applied at the reproductive stage, a very strict growing condition for upland rice. The non-genetically modified cultivar (NGM) under drought treatment reduced productivity by 89% compared with that under irrigated treatment, whereas transformed plants (PLD&1_E2) reduced productivity by only 41%. After the drought treatment, the PLD&1_E2 plants productivity was five times greater than that of the NGM plant. Moreover, no adverse effects on growth and development of the transgenic plants were observed. Seven days after the resumption of irrigation, PLD&1_E2 plants had higher stomatal conductance, greater photosynthetic rate, and transpiration rate than did NGM plants, as well as a higher expression level of the OsPLD&1 gene. A delay in the senescence process was observed in these PLD&1_E2 plants, and this was determined for the recovery of photosynthesis, with greater expression of the Rubisco and lower expression of the SOD. This finding was suggestive of decreased oxidative stress, probably due to gas exchange by the partial closure of the stomata of these transformed plants, which prevented the formation of reactive oxygen species. OsPLD&1 gene overexpression resulted in a reduction in production loss under severe water deficit and revealed a possibility for the development of upland rice cultivars that are more tolerant to extreme drought conditions.
