Yet, this trait raises a fundamental question: how are seed-specific abscisic acid (ABA) responses modulated to support continuous embryonic growth without compromising ABA-dependent vegetative stress tolerance? Here, integrating phylogenomic analyses of independently evolved (crypto)viviparous lineages with spatiotemporal transcriptomics and functional validation, we show that (crypto)vivipary evolved via a convergent \u201cless-is-more\u201d strategy rather than through novel genes or single master loci (e.g.,\n                    <jats:italic toggle=\"yes\">DOG1<\/jats:italic>\n                    ). While upstream hormonal cores (e.g., ABA\/GA signaling) are largely conserved, downstream seed desiccation and dormancy effectors are asymmetrically dismantled across cryptoviviparous and viviparous lineages. This remodeling, encompassing 38 shared contracted orthogroups and hundreds of lineage-specific losses, converges on eliminating the execution machinery for seed desiccation tolerance and dormancy maintenance. Consistently, orthologs of the contracted genes are enriched for dry-seed\u2013specific expression and ABA responsiveness in non-(crypto)viviparous species. Furthermore, disrupting representative\n                    <jats:italic toggle=\"yes\">Arabidopsis<\/jats:italic>\n                    orthologs (e.g.,\n                    <jats:italic toggle=\"yes\">SESA1<\/jats:italic>\n                    ,\n                    <jats:italic toggle=\"yes\">TIP3.2<\/jats:italic>\n                    ,\n                    <jats:italic toggle=\"yes\">LEA25<\/jats:italic>\n                    ,\n                    <jats:italic toggle=\"yes\">ECP63<\/jats:italic>\n                    ) recapitulates (crypto)viviparous-like phenotypes, including precocious germination, elevated seed moisture, and in most mutants, compromised storage longevity. Together, our findings demonstrate how structured contraction of terminal seed-specific modules uncouples seed developmental fate from systemic stress signaling, illuminating the molecular architecture of (crypto)vivipary.\n
