Summary: In this study, Bambusa changningensis, a new bamboo species, was identified as a natural hybrid through analysis of morphological characteristics, DNA markers, DNA barcoding, and chloroplast genomes. The results suggested that B. rigida might be the female parent of B. changningensis. This study provides evidence for natural hybridization in bamboo and is the first to confirm a natural bamboo hybrid and its parents through SSR and chloroplast genome sequence.

Summary: In this study, pulps from Bambusa vulgaris and Dendrocalamus asper were compared to industrially produced Eucalyptus spp. pulp in terms of morphology and mechanical properties. The pulping processes of Bambusa vulgaris and Dendrocalamus asper resulted in total yields of 71.3% and 77.0% respectively. Both bamboo species had higher mechanical properties compared to Eucalyptus spp. pulp. Bambusa vulgaris pulp showed superior mechanical properties and required less energy for refining, making it suitable for applications requiring high tensile strength. Dendrocalamus asper pulp demonstrated higher bulk and liquid absorption capacity, making it more suitable for certain applications.

Summary: This study examined the development of three stages of flowers in Dendrocalamus asper and Bambusa tuldoides. The gynoecium in these stages was analyzed using scanning electron microscopy and light microscopy techniques. The results revealed that B. tuldoides formed two megaspores in the first stage, while D. asper formed the megaspore mother cell in the second stage. The absence of caryopsis formation was found to be related to the failure in the development of pollen grains and early inbreeding depression. This absence of seeds negatively affects genetic variability, which is crucial for genetic improvement programs and conservation of plant genetic resources.

Summary: This study investigated the origin and spread of the Bemisia tabaci B mitotype outbreaks in Brazil in 1991. The results revealed a previously undocumented hybridization event, with the B mitotype likely being a hybrid between a B type parent related to Ethiopian endemism and an unidentified parent from the North Africa-Middle East region. The study also found evidence of two independent introductions of the B mitotype in Brazil in 1989 and 1990, which together led to the complete invasion of Brazil in just 30 generations.

This study examines the conservation genetics of economically exploited tree species in the vulnerable Atlantic Forest of Brazil. Genetic parameters of 10 species were compiled, revealing differences in genetic variability and unique alleles. Comparison of data between ontogenic stages suggests that habitat loss has not yet caused significant loss of genetic diversity.
