Wood transcriptome analysis and expression variation of lignin biosynthetic pathway transcripts in Roxb., a multi-purpose tropical tree species.

Safety matches are an essential consumer commodity which faces considerable shortage of raw material due to specific requirements like color, wax stability, consistent burning and splinting ability in wood. Roxb. is a multi-purpose tropical tree species which is predominantly used for production of match splints.

Targeted re-sequencing and genome-wide association analysis for wood property traits in breeding population of Eucalyptus tereticornis × E. grandis.

Globally, Eucalyptus plantations occupy 22 million ha area and is one of the preferred hardwood species due to their short rotation, rapid growth, adaptability and wood properties. In this study, we present results of GWAS in parents and 100 hybrids of Eucalyptus tereticornis × E. grandis using 762 genes presumably involved in wood formation.

Quantitative genetic analysis of wood property traits in biparental population of × .

breeding programme mainly aims at increasing productivity associated with wood property traits which are suitable for different end uses. The principal challenge in this endeavor is to combine productivity with industrially relevant wood traits. In the present study, 23 hybrid clones derived from a biparental mapping population of × was assessed for six wood property traits across two sites in Tamil Nadu, India.

Genetic linkage map and QTL identification for adventitious rooting traits in red gum eucalypts.

The eucalypt species, and , show tolerance to drought and salinity conditions, respectively, and are widely cultivated in arid and semiarid regions of tropical countries. In this study, genetic linkage map was developed for interspecific cross  ×  using pseudo-testcross strategy with simple sequence repeats (SSRs), intersimple sequence repeats (ISSRs), and sequence-related amplified polymorphism (SRAP) markers. The consensus genetic map comprised totally 283 markers with 84 SSRs, 94 ISSRs, and 105 SRAP markers on 11 linkage groups spanning 1163.

Quantitative trait loci mapping for stomatal traits in interspecific hybrids of Eucalyptus.

Eucalyptus is an important industrial species with tolerance to drought and salt stress. Genetic improvement activities including quantitative trait loci (QTL) mapping for pulping and adventitious rooting traits are in progress, but no information is available on the genomic regions on adaptive traits such as stomatal characteristics. In this study, an interspecific cross between Eucalyptus tereticornis and E.
