Xylella fastidiosa, the causal agent of almond leaf scorch disease (ALSD), is currently re-emerging as a serious concern in California. Efficient pathogen detection is critical for ALSD epidemiological studies, particularly when a large sample size is involved. We here report a PCR procedure to detect X. fastidiosa directly from infected almond tissue without the laborious DNA extraction. Plant...

The use of biostimulants has become a common practice in agriculture. However, there is little peer-reviewed research on this topic. In this study we tested, under controlled and replicated conditions, the effect of one biostimulant derived from seaweed extraction (Bio-1) and another biostimulant derived from microbial fermentation (Bio-2). This experiment utilized 2-years-old almond plants ove...

Recently, our laboratory reported the isolation of Cryptococcus neoformans var. gattii, serotype C for the first time from almond trees (Terminalia catappa) detritus. The aim of the present study was to establish the survival of C. neoformans in almond trees seedlings. Thirty seedlings were infected in the stems and samples were taken and processed at different times and by different techniques...

Sir,?At page 191 of Valentine Baker's Clouds in the East, he mentions, that when suffering from dysentery, near Meshed, he got from an official, Abbas Khan, a remedy "called in Persia barhangIt consisted of a small seed somewhat resembling linse ed, and was made into a tea like linseed tea, with the addition of a teaspoonful of oil of sweet almonds." "Diet was restricted to rice and a wash of s...

The seeds of the almond tree [(Prunus dulcis (Mill.) D. A. Webb. (syn. Prunus amygdalus)] were collected in two different periods of maturity and were studied for their lipid content. The total lipids (TL) were extracted by the Bligh-Dyer method and the lipid classes have been isolated by chromatographic techniques and were analyzed by HPTLC coupled with a flame ionization detector (HPTLC/FID) ...

Amygdalin is a cyanogenic diglucoside and constitutes the bitter component in bitter almond (Prunus dulcis). Amygdalin concentration increases in the course of fruit formation. The monoglucoside prunasin is the precursor of amygdalin. Prunasin may be degraded to hydrogen cyanide, glucose, and benzaldehyde by the action of the β-glucosidase prunasin hydrolase (PH) and mandelonitirile lyase or be...
