The first mitochondrial genome of Calophyllum soulattri Burm.f.

Calophyllum soulattri Burm.f. is traditionally used to treat skin infections and reduce rheumatic pain, yet genetic and genomic studies are still limited.

The complete chloroplast genome of Burm. f. (Calophyllaceae).

Burm. f. (1768) is an evergreen tree native to Southeast Asia, Australia, and the Solomon Islands.

Simultaneous improvement and genetic dissection of drought and submergence tolerances in rice ( L.) by selective introgression.

Introduction: Drought and submergence are contrasting abiotic stresses that often occur in the same rice crop season and cause complete crop failure in many rain-fed lowland areas of Asia.

Methods: To develop rice varieties with good tolerances to drought and submergence, 260 introgression lines (ILs) selected for drought tolerance (DT) from nine BC populations were screened for submergence tolerance (ST), resulting in 124 ILs with significantly improved ST.

Results: Genetic characterization of the 260 ILs with DNA markers identified 59 DT quantitative trait loci (QTLs) and 68 ST QTLs with an average 55% of the identified QTLs associated with both DT and ST.
