Background- Aneuploidy is associated with add or lack of individual chromosomes. The knowledge regarding aneuploidy is still rare in wild and tropical populations. Lippia alba is a tropical polyploid complex naturally formed, with 2x, 3x, 4x, 6x, and aneuploid individuals. The species presents pharmacological and medicinal importance, due to its essential oil compounds, which are related to the ploidal level. Considering the singularity of aneuploids emergence and stability, we proposed to investigate putative cytotypes involved in the aneuploids formation. Methods and results - Molecular, cytogenetic, reproductive, and chemical approaches were adopted. The results showed that the aneuploids possibly have independent origin considering the genetic, chemical and karyotypical profiles. The chemical composition of aneuploids is related to genetic similarity. The aneuploid origin may involve 2x and 3x cytotypes being possible to rise four scenarios of crosses to explain that. Conclusions -The results, in general, contribute to the comprehension of the origin of aneuploids and highlight the genetic profile of these accessions as a key element on the understanding of the chemical profile of L. alba accessions. |

Ceropsylla pouteriae Burckhardt sp. nov. is described and illustrated from Brazil: Minas Gerais. It induces pit galls on the leaves of Pouteria ramiflora (Mart.) Radlk. (Sapotaceae), a characteristic tree of the Cerrado biome. The previously artificial genus Ceropsylla is redefined and six species are transferred from Ceropsylla to Trioza as Trioza angustirerta (Li, 2011), comb. nov., Trioza celticola (Li, 2011), comb. nov., Trioza cestolemba (Li, 2011), comb. nov., Trioza discrepans (Tuthill, 1945), comb. nov., Trioza martorelli (Caldwell, 1942), comb. nov. and Trioza pulchra (Tuthill, 1945), comb. nov. The psyllids on Sapotaceae are reviewed and the phylogenetic relationships of Ceropsylla briefly discussed. The Ceropsylla pouteriae gall develops from cellular hypertrophy and hyperplasia of the mesophyll leaf tissue, as well as neoformation of vascular tissues. The hypertrophy of the palisade parenchyma cells leads to the formation of the adaxial cortex of the gall. The abaxial cortex originates from the spongy parenchyma. The elongation of the adaxial and abaxial cortex is responsible for the intralaminar gall shape. The neoformation of vascular bundles is an important feature for the phloem feeding Ceropsylla pouteriae. The intralaminar morphotype of the C. pouteriae gall showed a simple anatomical structure. It lacks defence-related compounds and nutritive tissue. The structural simplicity contrasts with the presence of chemical substances in the gall tissue. |
