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

Plant 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

Plant 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.

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

Plant 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.

TaRIP2 Positively Regulates Wheat Pollen Wall Formation Through MYB80‐Controlled Lipid Metabolism

Plant Biotechnology Journal, EarlyView.
ABSTRACT Male‐sterile genes and mutants are critical for hybrid seed production in monocotyledonous crops. Lipids are essential structural components of male reproductive organs, such as the anther and pollen. Here, we show that the pollen‐preferential gene TaRIP2 is essential for wheat anther development and pollen formation. RT‐qPCR analysis revealed
