Abstract
Genes related to the response to drought stress in leaf and root tissue of
drought-susceptible (DS) and tolerant (DT) genotypes were characterized by
RNA-Seq. In total, 54,750 transcripts, representative of 28,590 genes, were
identified; of these, 1,648 were of high-fidelity (merge of 12 libraries) and
described for the first time in the Andean germplasm. From the 1,239
differentially expressed genes (DEGs), 458 were identified in DT, with a
predominance of genes in categories of oxidative stress, response to stimulus
and kinase activity. Most genes related to oxidation-reduction terms in roots
were early triggered in DT (T75) compared to DS (T150) suggestive of a mechanism
of tolerance by reducing the damage from ROS. Among the KEGG enriched by DEGs
up-regulated in DT leaves, two related to the formation of Sulfur-containing
compounds, which are known for their involvement in tolerance to abiotic
stresses, were common to all treatments. Through qPCR, 88.64% of the DEGs were
validated. A total of 151,283 variants were identified and functional effects
estimated for 85,780. The raw data files were submitted to the NCBI database. A
transcriptome map revealed new genes and isoforms under drought. These results
supports a better understanding of the drought tolerance mechanisms in
beans.

Abstract
Eighty-one Rhizoctonia-like isolates were identified based on morphology and nuclei-staining methods from natural and agricultural soils of the Cerrado (Brazilian savanna). The nucleotide similarity analysis of ITS1-5.8S-ITS2 regions identified 14 different taxa, with 39.5% of isolates assigned to Waitea circinata (zeae, oryzae, and circinata varieties), while 37.0% belonged to Thanatephorus cucumeris anastomosis groups (AGs) AG1-IB, AG1-ID, AG1-IE, AG4-HGI, and AG4-HGIII. Ceratobasidium spp. AG-A, AG-F, AG-Fa, AG-P, and AG-R comprised 23.5%. Rhizoctonia zeae (19.8%), R. solani AG1-IE (18.6%), and binucleate Rhizoctonia AG-A (8.6%) were the most frequent anamorphic states found. Root rot severity caused by the different taxa varied from low to high on common beans, and tended to be low to average in maize. Twenty-two isolates were pathogenic to both hosts, suggesting difficulties in managing Rhizoctonia root rots with crop rotation. These results suggest that cropping history affects the geographical arrangement of AGs, with a prevalence of AG1 in the tropical zone from central to north Brazil while the AG4 group was most prevalent from central to subtropical south. W. circinata var. zeae was predominant in soils under maize production. To our knowledge, this is the first report on the occurrence of W. circinata var. circinata in Brazil.
