Artificial Mutations in the Nuclear Gene Encoding Mitochondrial RNA Polymerase Restore Pollen Fertility in Cytoplasmic Male Sterile Tomato

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Cytoplasmic male sterility (CMS) and restorer of fertility (Rf) are important traits in F1 hybrid breeding. However, the CMS/Rf system has not been used in tomatoes because of the limited resources of Rf lines. In this study, we performed mutagenesis in tomato CMS seeds and successfully obtained 13 suppressor mutants with pollen fertility ...

Perturbation of Anion/Cation Transport Leads to Apical Panicle Abortion in Rice by Disrupting Ca2+ Homeostasis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Calcium ion (Ca2+) is an essential plant nutrient required for cell structure establishment, as well as a counter‐cation of an anion and an intracellular messenger. Calcium is absorbed from soil by roots and delivered to shoots through the xylem. The process must be finely balanced to avoid excessive accumulation.

Induction of Synthetic Apomixis in Two Sorghum Hybrids Enables Seed Yield and Genotype Preservation Over Multiple Generations

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Induction of apomixis, or clonal reproduction through seed, could economise commercial hybrid seed production and enable smallholder farmers to save and sow hybrid seed. Here, we demonstrate the synthetic induction of apomixis in two sorghum hybrids and show that the clonal hybrid seed can be maintained across multiple seed generations.

Developing an Efficient System for Hybrid Rice Seed Production Using Partial Male Sterility

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Efficient production of hybrid rice seeds requires male sterility systems to overcome the challenges of self‐pollination. In this study, we identified male gametic transfer defect (GTrD)5 and GTrD9 as essential genes for the process of male gamete transmission in rice.

Transcriptional Regulation of SWEET15_A01 by MYB44/bHLH3 Modulates Carbon Allocation in Cotton Ovule and Fibre to Affect Seed and Fibre Traits

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The allocation of carbon sources between cotton ovule and fibre significantly influences the yield and quality of seed and fibre. SWEET15 (Sugars Will Eventually be Exported Transporter 15) plays a key role in sucrose transport; however, the transcriptional regulation of SWEET15 in cotton remains unclear.

The Evolution and Origin of Allotetraploid Aegilops geniculata Revealed by the Homoeolog‐Resolved Genome Assembly

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Aegilops geniculata Roth is a tetraploid (MgMgUgUg; 2n = 4x = 28) wild relative of wheat and a valuable source of genetic diversity for improving agronomic traits. We present a high‐quality homoeolog‐resolved assembly and annotation of the Ae.

Heat Shock Transcription Factor OsHsfc1a Enhances Rice Seedling Thermotolerance by Regulating OsMFT1 and Preserving Chloroplast Structure Under Heat Stress

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT High‐temperature stress severely threatens rice (Oryza sativa L.) growth and productivity, particularly during the seedling stage, making heat tolerance an essential breeding target. In this study, we identified the heat shock transcription factor OsHsfc1a as a positive regulator of thermotolerance in rice seedlings.

TKC‐MC: An Effective Strategy for Generating Heritable Heterozygous Mutations in Essential Genes in Rice

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The CRISPR/Cas9 gene‐editing technology has been widely used in defining gene functions and crop improvement. However, some genes are essential for plant growth and development. Loss‐of‐function homozygous mutations in essential genes lead to plant death or sterility.
