In April-August 2018, samples of galled roots with rhizosphere soil were collected from almond orchards in Atwater, Merced County and Bakersfield, Kern County, California. Almond trees () grafted on 'Hansen 536' and 'Brights Hybrid5' (peach-almond hybrid) rootstocks showed strong symptoms of growth decline. Extracted root-knot nematodes were identified by both morphological and molecular methods as . was initially found in Florida, USA, and has not been reported from any other states and countries. This is a first report of in California and outside of Florida.

Fine-root and leaf acquisitive traits decoupled from chloride accumulation in reflecting the differential salinity tolerance among hybrids.

Improving crop salinity management requires enhanced understanding of salinity responses of leaf and fine-root traits governing resource acquisition, ideally in relation to ion accumulation at intra- or inter-specific levels. We hypothesized that these responses are coupled towards integrated resource conservation for plants under prolonged salt treatment. We tested the hypothesis with a glasshouse experiment on saplings of six contrasting hybrids, subjected to either control or salt treatment (reverse osmosis water versus 3.

Agricultural Research Service, U.S. Horticultural Research Laboratory, 2001 South Rock Road, Ft. Pierce, FL, USA.
The data are aerial images and ground tree measurement data of 3 citrus rootstock trials. Developing new citrus rootstock varieties requires field trials to test to identify selections with improved horticultural performance. A bud from a scion variety is grafted onto the rootstock and grown in a nursery until the grafted plant is ready to be planted in the field, which is in about one year.

Peach-associated luteovirus (PaLV) belongs to the genus Luteovirus, family Tombusviridae. To date, PaLV has only been reported in peach (Prunus persica) and its presence detected in the Republic of Georgia (Wu et al., 2017), China (Zhou et al.

Article Synopsis
- Huanglongbing (HLB) disease, triggered by the bacterium Liberibacter asiaticus, poses a serious threat to citrus production with no existing cure, making the development of resistant cultivars essential.
- Researchers focused on the NONEXPRESSOR OF PATHOGENESIS-RELATED GENES (NPR) family, specifically modifying NPR1 and NPR3 genes in sweet orange trees to improve HLB resistance.
- The genome-edited sweet orange varieties showed enhanced vigor compared to wild-type trees under greenhouse conditions, suggesting that targeted gene editing can help in developing HLB-tolerant citrus plants, although further field tests are required to confirm these results.
