“…An alternative is searching for genetically resistant organisms, mainly through the prospection of genes to subside genetic breeding. Qualitative resistance genes, known as R genes, are part of the detection mechanism of foreign organisms, such as pathogens, by interacting with the avirulent gene (Avr) after the attack [24,25]. Recognition proteins encoded by R genes are predominantly intracellular receptors with high target speci city.…”

I. Background: Plant phenotyping has been a bottleneck for selecting insect-resistant plants in breeding programs. Our objectives were to: use text-mining tools to investigate state of the art about Leptocybe invasa in Eucalyptus; identify associated molecular interactions involving genes as a candidate and their impact and associated metabolites pathways and determine how products are currently used to control this insect as patents. II. Methods and Results: The literature survey was explored by title, abstract, and keywords of scientific articles, a database of genes and protein sequences, and patents. Nucleotide and protein sequences were mined in public banks. In the literature, we searched for homology to known genes or predicted proteins with sequences described in Eucalyptus sp. To obtain a broad set of studies, we accessed literature data of the last 20 years conducted with combinations of search terms “Leptocybe invasa” OR “eucalyptus gall wasp” AND “control”. Patents were prospected and analyzed using Orbit Intelligence patent research software III. Conclusions: Succinct interpretation of results as well as significance of findings. Statement There are perspectives to access the genotype resistance; furthermore, it is critical managing the evaluable information as state of the art to overcome the damages of L. invasa beyond the genotype selection. The target genes found in this research can serve as a basis for further functional characterizations of Eucalyptus genes possibly related to response expression to L. invasa.

Our study aimed to enhance the current understanding of Leptocybe invasa, a pest affecting Eucalyptus trees, by exploring the intricate molecular interactions between plants and insects. Specifically, we sought to identify key genes and metabolic pathways involved in these plant-insect interactions to develop innovative strategies for effective pest control. To accomplish this, we embarked on a comprehensive investigation utilizing an array of scientific resources, including scientific articles, gene and protein sequence databases, and patents. This comprehensive search enabled us to gather valuable information on gene homology and predicted proteins specific to Eucalyptus species. Furthermore, we conducted an in-depth literature review that focused on the latest advancements in gene expression research and the intricate world of secondary metabolites. Through this exploration, we gained critical insights into the underlying mechanisms of plant resistance and the potential application of specific genes in selecting resilient Eucalyptus genotypes capable of withstanding the challenges posed by L. invasa. Our search for patents was facilitated by the utilization of the cutting-edge Orbit Intelligence patent research software, which allowed us to identify novel approaches and innovations in the field of pest control. This study underscores the significance of performing a meta-analysis that incorporates advancements in gene expression research and the exploration of secondary metabolite data. Such an approach deepens our understanding of plant resistance mechanisms, paving the way for the identification and selection of L. invasa resistant genotypes. Ultimately, our findings hold promise for the development of effective strategies to mitigate the impact of this destructive pest on Eucalyptus trees.

The present study measured the growth traits of 98 open-pollinated half-sibling families from the second-generation clonal seed orchard of Chinese fir for 6 consecutive years from age 2 to 7, the change patterns of genetic variation in growth traits and genetic parameters were analyzed, and best linear unbiased prediction (BLUP) was used for early selection to determine the excellent families. The growth traits of Chinese fir revealed highly significant differences between families, indicating that there was significant genetic variation at the family level, which serves as the foundation for exceptional family selection. The heritabilities of family and individual for H (height) ranged from 0.61 to 0.65 and 0.41 to 0.46, respectively; for DGH (the diameter at ground height)/DBH (the diameter at breast height), they were 0.55 to 0.66 and 0.35 to 0.46, respectively; and for V (tree volume), they were 0.66 to 0.70 and 0.48 to 0.49, respectively. The growth traits of genetic control were at a greater level at age 5. The findings of the coefficient of variation analysis demonstrated that the phenotypic variation coefficient were larger than the genetic variation coefficient for three growth traits at various ages. The juvenile-mature genetic and phenotypic correlations revealed an increasing tendency with age, and mainly controlled by genetic factors. Compared to other age groups for growth traits, age 5 had greater phenotypic and genetic association coefficients, as well as greater efficiency of early selection. Based on the selection method of breeding value, nine families were selected with a 9.2 % selection rate.
