Abstract:Rice is the staple food for about half of the world population. Rice grain yield and qualityare affected by climatic changes. Arguably, rice cultivars genetic diversity is diminished from decadesof breeding using narrow germplasm, requiring introgressions from otherOryzaspecies, weedy orwild. Weedy rice has high genetic diversity, which is an essential resource for rice crop improvement.Here, we analyzed the phenotypic, physiological, and molecular profiles of two rice cultivars (IRGA424 and SCS119 Rubi) and five weedy rice (WR), from five different Brazilian regions, in responseto heat and drought stress. Drought and heat stress affected the phenotype and photosyntheticparameters in different ways in rice and WR genotypes. A WR from Northern Brazil yielded betterunder heat stress than the non-stressed check. Drought stress upregulatedHSF7Awhile heat stressupregulatedHSF2a.HSP74.8,HSP80.2,andHSP24.1were upregulated in both conditions. Basedon all evaluated traits, we hypothesized that in drought conditions increasingHSFA7expressionis related to tiller number and that increase WUE (water use efficiency) andHSFA2aexpressionare associated with yield. In heat conditions, Gs(stomatal conductance) and Es increases may berelated to plant height; tiller number is inversely associated withHSPsexpression, and chlorophyllcontent and Ci(intercellular CO2concentration) may be related to yield. Based on morphology,physiology, and gene regulation in heat and drought stress, we can discriminate genotypes thatperform well under these stress conditions and utilize such genotypes as a source of genetic diversityfor rice breeding.Keywords:genetic diversity; photosynthesis; heat shock protein MenosAbstract:Rice is the staple food for about half of the world population.

ABSTRACT - The objective of this work was to describe the sexual dimorphism and mating behavior of Lobiopa insularis for the development of pest control and management programs. The morphological characteristics for separating males and females were described with the aid of a stereomicroscope. Mating sequence was recorded over 72 hours with a digital camera. There are differences between males and females in the last abdomen segments, and males maintain a guarding position after mating. The obtained data can be used in monitoring programs to precisely identify the sex of the insects, also shedding light on the ecological features of this pest and Nitidulidae. RESUMO - O objetivo deste trabalho foi descrever o dimorfismo sexual e o comportamento de cópula de Lobiopa insularis, para o desenvolvimento de programas de controle e manejo de pragas. As características morfológicas para separação de machos e fêmeas foram descritas com auxílio de estereomicroscópio. A sequência de cópula foi registrada por 72 horas com câmera digital. Há diferenças entre machos e fêmeas nos segmentos finais do abdômen, e os machos mantêm posição de guarda após a cópula. Os dados obtidos podem ser usados em programa de monitoramento para uma identificação precisa do sexo do inseto, além de lançarem luz sobre os traços ecológicos desta praga e de Nitidulidae. |
