TLDR
This review presents an alternative approach to increase lodging resistance by improving the quality of the culm by identifying genes related to culm quality and introducing these genes into high-yielding rice cultivars through molecular breeding technique.Abstract:
Traditional breeding for high-yielding rice has been dependent on the widespread cultivation of gibberellin (GA)-deficient semi-dwarf varieties. Dwarfism lowers the "center of gravity" of the plant body, which increases resistance against lodging and enables plants to support high grain yield. Although this approach was successful in latter half of the 20th century in rice and wheat breeding, this may no longer be enough to sustain rice with even higher yields. This is because relying solely on the semi-dwarf trait is subject to certain limitations, making it necessary to use other important traits to reinforce it. In this review, we present an alternative approach to increase lodging resistance by improving the quality of the culm by identifying genes related to culm quality and introducing these genes into high-yielding rice cultivars through molecular breeding technique.read more

Submergence and Waterlogging Stress in Plants: A Review Highlighting Research Opportunities and Understudied Aspects
TL;DR: Parts of submergence/waterlogging stress that have not yet been thoroughly studied at the molecular level in this context are highlighted, such as miRNA and retrotransposon expression, the influence of light/dark cycles, protein isoforms, root architecture, sugar sensing and signaling, post-stress molecular events, heavy-metal and salinity stress, and mRNA dynamics.

Revolutions in agriculture chart a course for targeted breeding of old and new crops
TL;DR: It is argued that in the short term, more legumes such as beans are the best option, and in such plants targeted changes in antiflorigen genes were and will continue to be key for large-scale production.

TL;DR: It is shown that Rht-B1/Rht-D1 and maize dwarf-8 (d8), are orthologues of the Arabidopsis Gibberellin Insensitive (GAI) gene, which encode proteins that resemble nuclear transcription factors and contain an SH2-like domain, indicating that phosphotyrosine may participate in gibberelli signalling.

TL;DR: It is shown that a QTL that increases grain productivity in rice, Gn1a, is a gene for cytokinin oxidase/dehydrogenase (OsCKX2), an enzyme that degrades the phytohormone cytokinIn.

GS3, a major QTL for grain length and weight and minor QTL for grain width and thickness in rice, encodes a putative transmembrane protein

TL;DR: Analysis of a random subpopulation of 201 individuals from the BC3F2 progeny confirmed that the GS3 locus explained 80–90% of the variation for grain weight and length in this population, and this locus was resolved as a minor QTL for grain width and thickness.

TL;DR: It is demonstrated that a point mutation in OsSPL14 perturbs OsmiR156-directed regulation of OsSPl14, generating an 'ideal' rice plant with a reduced tiller number, increased lodging resistance and enhanced grain yield.

TL;DR: The chronic food shortage that was feared after the rapid expansion of the world population in the 1960s was averted largely by the development of a high-yielding semi-dwarf variety of rice known as IR8, the so-called rice 'green revolution'; this gene is identified as encoding an oxidase enzyme involved in the biosynthesis of gibberellin, a plant growth hormone.
