Plant Biotechnology Journal, EarlyView.Conceptual overview of programmable de novo domestication from genetic diversity discovery to crop deployment. The framework connects diverse germplasm and genomic resources with three trajectory pathways. Adaptive Rescue, Agronomic Refinement and Novel Chassis defined by biological distance, engineering complexity and breeding objectives.

Plant Breeding, EarlyView.ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Plant Breeding, EarlyView.ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

Ploidy in cardiovascular development and regeneration
Seminars in Cell & Developmental BiologySomatic polyploidy, a non-inheritable form of genome multiplication, plays cell-type specific and context-dependent roles in organ development and regeneration. In the mammalian heart, embryonic cardiomyocytes are primarily diploid, which lose their ability to complete cell division and become polyploid as they mature.

Plant Breeding, EarlyView.ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Plant Breeding, EarlyView.ABSTRACT Peanut (Arachis hypogaea L., 2n = 4x = 40, AABB) is an important legume crop worldwide. Wild peanuts (Arachis spp.) represent a valuable secondary gene pool with diverse disease resistances. However, most wild peanut species are diploid (2n = 2x = 20) and this ploidy barrier is a major obstacle to hybridization and gene introgression.

Plant Breeding, EarlyView.ABSTRACT Unreduced gametes naturally promote polyploidization and are valuable in breeding polyploid offspring. Bigleaf hydrangea (Hydrangea macrophylla ssp. macrophylla), a major ornamental crop, has shown spontaneous polyploidization rates ranging from 0% to 94% in previous crosses.

Plant, Cell &Environment, EarlyView.ABSTRACT The anaphase‐promoting complex/cyclosome (APC/C) is a multi‐subunit E3 ubiquitin ligase that regulates cell cycle progression, but its role in plant‐pathogen interactions is poorly understood. Here, we demonstrate that regulation of the ubiquitin–proteasome system, involving APC/C‐associated components, is critical for coordinating host cell ...

Effects of crossing distance on components of fitness in two rare rock plants
Plant Biology, EarlyView.Crossing experiments between populations of the rare rock species Saxifraga rosacea ssp. rosacea (8×) and S. rosacea ssp. sponhemica (6×) resulted in heterosis for some traits and outbreeding depression for others. Crossing the two subspecies resulted in sterile hybrids indicating that mixing populations of rare species is not always beneficial ...
