A Step-by-step Protocol for Crossing and Marker-Assisted Breeding of Asian and African Rice Varieties.

Improving desirable traits of popular rice varieties is of particular importance for small-scale food producers. Breeding is considered the most ecological and economic approach to improve yield, especially in the context of pest and pathogen-resistant varieties development. Being able to cross rice lines is also a critical step when using current transgene-based genome editing technologies, e.

Closing the information gap between the field and scientific literature for improved disease management- with a focus on rice and bacterial blight.

A path to sustainably reduce world hunger, food insecurity, and malnutrition is to close the crop yield gap, particularly, losses due to pathogens. Breeding resistant crops is key to achieving this goal, an effort requiring collaboration among stakeholders, scientists, breeders, farmers and policymakers. During a disease outbreak, epidemiologists survey the occurrence of a disease after which pathologists investigate mechanisms to stop an infection.

Genome editing of an African elite rice variety confers resistance against endemic and emerging pv. strains.

Bacterial leaf blight (BB) of rice, caused by pv. (), threatens global food security and the livelihood of small-scale rice producers. Analyses of collections from Asia, Africa and the Americas demonstrated complete continental segregation, despite robust global rice trade.

Recognition of Microbe- and Damage-Associated Molecular Patterns by Leucine-Rich Repeat Pattern Recognition Receptor Kinases Confers Salt Tolerance in Plants.

In plants, a first layer of inducible immunity is conferred by pattern recognition receptors (PRRs) that bind microbe- and damage-associated molecular patterns to activate pattern-triggered immunity (PTI). PTI is strengthened or followed by another potent form of immunity when intracellular receptors recognize pathogen effectors, termed effector-triggered immunity. Immunity signaling regulators have been reported to influence abiotic stress responses as well, yet the governing principles and mechanisms remain ambiguous.

Cellular export of sugars and amino acids: role in feeding other cells and organisms.

Sucrose, hexoses, and raffinose play key roles in the plant metabolism. Sucrose and raffinose, produced by photosynthesis, are translocated from leaves to flowers, developing seeds and roots. Translocation occurs in the sieve elements or sieve tubes of angiosperms.
