Allelic Diversity at Abiotic Stress Responsive Genes in Relationship to Ecological Drought Indices for Cultivated Tepary Bean, Phaseolus acutifolius A. Gray, and Its Wild Relatives.

Some of the major impacts of climate change are expected in regions where drought stress is already an issue. Grain legumes are generally drought susceptible. However, tepary bean and its wild relatives within Phaseolus acutifolius or P. parvifolius are from arid areas between Mexico and the United States. Therefore, we hypothesize that these bean accessions have diversity signals indicative of adaptation to drought at key candidate genes such as: Asr2, Dreb2B, and ERECTA. By sequencing alleles of these genes and comparing to estimates of drought tolerance indices from climate data for the collection site of geo-referenced, tepary bean accessions, we determined the genotype x environmental association (GEA) of each gene. Diversity analysis found that cultivated and wild P. acutifolius were intermingled with var. tenuifolius and P. parvifolius, signifying that allele diversity was ample in the wild and cultivated clade over a broad sense (sensu lato) evaluation. Genes Dreb2B and ERECTA harbored signatures of directional selection, represented by six SNPs correlated with the environmental drought indices. This suggests that wild tepary bean is a reservoir of novel alleles at genes for drought tolerance, as expected for a species that originated in arid environments. Our study corroborated that candidate gene approach was effective for marker validation across a broad genetic base of wild tepary accessions.

Reference evapotranspiration for Londrina, Paraná, Brazil: performance of different estimation methods / Evapotranspiração de referência para Londrina, Paraná: desempenho de diferentes métodos de estimativa

Aiming at assessing the performance of alternative methods to Penman-Monteith FAO56 for estimating the reference evapotranspiration (ETo) for Londrina, Paraná, Brazil, the methods temperature radiation, Hicks-Hess, Hargreaves-Samani (1982), Turc, Priestley-Taylor, Tanner-Pelton, Jensen-Haise, Makkink, modified Hargreaves, Stephens-Stewart, Abtew, global radiation, Ivanov, Lungeon, Hargreaves-Samani (1985), Benavides-Lopez, original Penman, Linacre, Blaney-Morin, Romanenko, Hargreaves (1974), McCloud, Camargo, Hamon, Kharrufa, McGuiness-Bordne, and Blaney-Criddle were compared to that standard method recommended by FAO. The estimations were correlated by linear regression and assessed by using the Persons correlation coefficient (r), concordance index (d), and performance index (c) using a set of meteorological data of approximately 40 years. The methods modified Hargreaves, Stephens-Stewart, Abtew, global radiation, Ivanov, Lungeon, Hargreaves-Samani (1985), Benavides-Lopez, original Penman, and Linacre should be avoided, as they did not present excellent results. The methods McCloud, Camargo, Hamon, Kharrufa, McGuinness-Bordne, Blaney-Criddle, Hargreaves (1974), Romanenko, and Blaney-Morin were classified as very bad, not being recommended. In contrast, the methods temperature radiation, Hicks-Hess, Hargreaves-Samani (1982), Turc, Priestley-Taylor, Tenner-Pelton, Jensen-Haise, and Makkink presented excellent performance indices and can beapplied in the study region.(AU)

Com objetivo de avaliar o desempenho de métodos alternativos ao Penmam-Monteith-FAO56 para a estimativa da evapotranspiração de referência (ETo) para a cidade de Londrina, Paraná, foram comparados a este método padrão recomendado pela FAO os seguintes métodos: Radiação-Temperatura, Hicks-Hess, Hargreaves-Samani-1982,Turc, Priestley-Taylor, Tanner-pelton, Jensen-Haise,Makkink, Hargreaves-Modificado, Stephens-Stewart, Abtew, Radiação-Global, Ivanov, Lungeon, Hargreaves-Samani-1985, Banavides-Lopez, Penman-Original, Linacre, Blaney-Morin, Romanenko, Hargreaves-1974, McCloud, Camargo, Hamon, Kharrufa, McGuiness-Bordne e Blaney-Criddle. Utilizando um conjunto de dados meteorológicos de aproximadamente 40 anos, as estimativas foram correlacionadas por regressão linear e avaliadas através do coeficiente de correlação de Person r, índice de concordância d e do índice de desempenho c. Os métodos Hargreaves Modificado, Stephens-Stewart, Abtew, Radiação-Global, Ivanov, Lungeon, Hargreaves-Samani-1985, Banvides-Lopez, Penman-Original e Linacre devem ser evitados, pois não apresentaram resultados ótimos. Classificado como péssimo os métodos McCloud, Camargo, Hamon, Kharrufa, McGuinness-Bordne, Blaney-Criddle, Hargreaves-1974, Romanenko e Blaney-Morin não são recomendados.
