This Project Grant award, provided by the United States Department of Agriculture's National Institute of Food and Agriculture (NIFA) under the Specialty Crop Research Initiative (CFDA 10.309), funds research to develop commercial citrus varieties with genetic resistance to Huanglongbing (HLB) disease. The award of $1,499,123 supports the University of Florida's efforts to use traditional techniques and gene editing to create HLB-resistant citrus rootstocks and scions, while also consolidating...
This $4,115,736 Project Grant award from the United States Department of Agriculture's (USDA) National Institute of Food and Agriculture (NIFA) under the Specialty Crop Research Initiative (CFDA 10.309) program supports research and extension activities to address critical challenges for the citrus industry related to Huanglongbing (HLB) disease. The primary objectives are to: 1) rapidly select, assess and deliver new HLB-resistant/tolerant citrus cultivars (rootstocks and scions) for fresh...
This Project Grant award of $1,125,000 from the U.S. Department of Agriculture's Specialty Crop Research Initiative (CFDA 10.309) is designed to identify genetic pathways and components that regulate callose and reactive oxygen species (ROS) accumulation to understand HLB (citrus greening) tolerance in citrus and its close relatives. The key objectives are to: 1) Use basal callose levels as a selection marker to identify HLB-tolerant citrus varieties in large germplasm collections, 2)...
The University of Florida (UF) was awarded a $1,364,478 Project Grant from the United States Department of Agriculture's (USDA) Specialty Crop Research Initiative (CFDA 10.309) program, effective September 15, 2023 through September 14, 2026. The grant supports research to develop citrus scions (fruit-bearing branches) that are tolerant to Huanglongbing (HLB), also known as citrus greening disease, a major threat to the U.S. citrus industry. Key objectives include verifying HLB tolerance in...
This federal Project Grant award of $6,854,123.64 was provided by the United States Department of Agriculture's National Institute of Food and Agriculture (USDA-NIFA) through the Specialty Crop Research Initiative (SCRI) program (CFDA 10.309). The purpose of the SCRI program is to address critical needs of the specialty crop industry, including fruits, vegetables, tree nuts, floriculture, and nursery crops, through research and extension activities. The grant funds a large-scale breeding and...
This federal Project Grant award, funded by the U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA) under the Specialty Crop Research Initiative (SCRI) program (CFDA 10.309), aims to expedite the release of non-transgenic, HLB-resistant/tolerant citrus varieties. The $6,172,615 grant, awarded on December 15, 2024, will support a multi-tiered research approach including: 1) assessment of previously generated genome-edited citrus plants for HLB...
The University of California, Riverside received a $1,365,000 Project Grant award from the U.S. Department of Agriculture (USDA) National Institute of Food and Agriculture (NIFA) Specialty Crop Research Initiative (SCRI) program. The project aims to develop non-transgenic, disease-resistant citrus varieties that can systemically express a heat-stable antimicrobial peptide (SAMP) to control citrus greening disease (Huanglongbing or HLB). The key objectives are to: 1) Introduce the SAMP gene...
The National Institute of Food and Agriculture (NIFA) awarded the University of Florida $8,589,573 under the Specialty Crop Research Initiative (SCRI) federal grant program on September 15, 2022 for a project set to conclude on September 14, 2027. The project aims to develop, evaluate, and deliver citrus Huanglongbing (HLB) management approaches by targeting its nature as a pathogen-triggered immune disease. Key products and services include developing integrated horticultural approaches to...
This $1,499,445 Project Grant was awarded by the U.S. Department of Agriculture's National Institute of Food and Agriculture (NIFA) under the Specialty Crop Research Initiative (SCRI) program (CFDA 10.309). The grant aims to develop and test methods to improve the efficacy and reduce the risk of phytotoxicity when using oxytetracycline trunk injections to treat Huanglongbing (HLB) disease in citrus trees in Florida, Texas, and California. Key objectives include: 1) improving the distribution...
The University of Florida (UF), through its Division of Sponsored Research, has been awarded a $928,000 Project Grant from the U.S. Department of Agriculture's Specialty Crop Research Initiative (SCRI) program (CFDA 10.309). The funding will support research to develop citrus varieties that are resistant or tolerant to Huanglongbing (HLB) or "citrus greening" disease, which poses a critical threat to the U.S. citrus industry. Specifically, the project aims to rapidly create...

This Project Grant award from the U.S. Department of Agriculture's National Institute of Food and Agriculture (NIFA) Specialty Crop Research Initiative (CFDA 10.309) provides $1,490,862 to the University of Florida to assess HLB-tolerant citrus rootstocks and interstocks. The objectives are to: 1) establish and evaluate field trials of novel HLB-tolerant rootstocks and interstocks in California and Florida; 2) validate genetic factors underlying HLB tolerance using advanced molecular techniques; 3) employ multi-omics approaches to identify and validate genetic markers for HLB tolerance; and 4) engage stakeholders through outreach to disseminate research findings and promote industry adoption of HLB-tolerant citrus varieties.

As a sub-award, the Regents of the University of California at Riverside will receive funding to support this project. Their work will focus on generating data to help growers make informed decisions on planting new acreage using the newly developed Australian lime cultivars as rootstocks or interstocks, with the goal of providing robust field tolerance to HLB.
