Abstract : Ongoing soil salinization drastically threatens crop growth, development, and yield worldwide. It is therefore crucial that we improve salt tolerance in rice by exploiting natural genetic variation. However, many salt-responsive genes confer undesirable phenotypes and therefore cannot be effectively applied to practical agricultural production. Here we successfully identified a quantitative trait locus (QTL) for salt tolerance from the African rice species Oryza glaberrima that we have named STH1. As an integration hub for salt tolerance and heading date, we found that STH1 regulates fatty acid metabolic homeostasis, probably through catalyzing the hydrolytic degradation of fatty acid, which contributes to salt tolerance. Meanwhile, we demonstrated that STH1 forms a protein complex with D3 and a vital regulatory factor in salt tolerance, OsHAL3, to affect the protein abundance of OsHAL3 by ubiquitination pathway. Furthermore, we revealed that STH1 also serves as a co-activator of the floral integrator gene Heading date 1 (Hd1) to balance the expression of the florigen gene Heading date 3a (Hd3a) under different circumstances, thus coordinating the regulation of salt tolerance and heading date. It is worth noting that the allele of STH1 associated with enhanced salt tolerance and high yield is partially found in African rice, but is hardly detected in Asian cultivars. Introgression of the allele of STH1(HP46) from African rice into modern rice cultivars is a desirable approach for boosting grain yield under salt stress. Collectively, our discoveries not only show basic conceptual advances about the mechanism for salt tolerance and synergetic regulation between salt tolerance and flowering time, but also provide strategies to overcome the challenges that result from increasingly serious soil salinization.

Abstract : Cultivated peanut (Arachis hypogaea) is an allotetraploid with closely related subgenomes of a total size of -2.7 Gb. This makes the assembly of chromosomal pseudomolecules very challenging. As a foundation to understanding the genome of cultivated peanut, we report the genome sequences of its diploid ancestors (Arachis duranensis and Arachis ipaensis). We show that these genomes are similar to cultivated peanut's A and B subgenomes and use them to identify candidate disease resistance genes, to guide tetraploid transcript assemblies and to detect genetic exchange between cultivated peanut's subgenomes. On the basis of remarkably high DNA identity of the A. ipaensis genome and the B subgenome of cultivated peanut and biogeographic evidence, we conclude that A. ipaensis may be a direct descendant of the same population that contributed the B subgenome to cultivated peanut.
