The high temperature stress-induced changes in chlorophyll a fluorescence parameters were used to study heat tolerance in nine accessions of common bean (Phaseolus vulgaris L.) received from the germplasm collection of “Maritsa” Vegetable Crops Research Institute and the Invstitute for Introduction and Plant Genetic Resources. The bean plants were treated for 2h at two temperatures, 23oC and 45...

Adult tomato psyllid, Bactericerca (Paratrioza) cockerelli (Sulc) (Homoptera: Psyllidae), behavioral responses were evaluated for five tomato plant lines and for the interactions of insecticides with four commercial cultivars. Plant lines tested included the commercial 'Shady Lady', 'Yellow Pear', '7718 VFN', 'QualiT 21', and the plant introduction line PI 134417. Insecticides included a kaolin...

Here we examined the properties of endosperm starches and the physical properties of cooked rice from four cultivars of Japanese upland rice containing M-type amylopectin (Chikanarijyun1, Kairyo13, Mogamichikanari1 and Hokkaiakage); S-type Nipponbare and L-type Kasalath served as standards. The amylopectin chain ratio (ACR ; ratio of the short chains of DP ≤ 10 to the short and intermediate cha...

In Arabidopsis, the regulation network of the seed maturation program controls the induction of seed dormancy. Wheat EST sequences showing homology with the master regulators of seed maturation, leafy cotyledon1 (LEC1), LEC2 and FUSCA3 (FUS3), were searched from databases and designated respectively as TaL1L (LEC1-LIKE), TaL2L (LEC2-LIKE), and TaFUS3. TaL1LA, TaL2LA and TaFUS3 mainly expressed ...

Plants are frequently exposed to microorganisms like fungi, bacteria, and viruses that cause biotic stresses. Fusarium head blight (FHB) is an economically risky wheat disease, which occurs upon Fusarium graminearum (Fg) infection. Moderately susceptible (cv. "Mizrak 98") and susceptible (cv. "Gun 91") winter type bread wheat cultivars were subjected to transcriptional profiling after exposure ...

Hydroponic greenhouse-grown and store-bought cultivars of tomato (cherry and beefsteak), cucumbers, bibb lettuce, and arugula were investigated to see if they could be distinguished based on sensory qualities and phytonutrient composition. Only the more dominant sensory criteriawere sufficiently robust to distinguish between cultivars and could form the core of a consolidated number of criteria...
