Pseudomonas turbinellae is a Gram-negative bacterium that causes bacterial leaf spot. It was first isolated on Cleome monophylla. [1] The type strain is ATCC 12446.
Blight refers to a specific symptom affecting plants in response to infection by a pathogenic organism.
Pinus monophylla, the single-leaf pinyon, is a pine in the pinyon pine group, native to North America. The range is in southernmost Idaho, western Utah, Arizona, southwest New Mexico, Nevada, eastern and southern California and northern Baja California.
A Leaf Spot is a limited, discoloured, diseased area of a leaf that is caused by fungal, bacterial or viral plant diseases, or by injuries from nematodes, insects, environmental factors, toxicity or herbicides. These discoloured spots or lesions often have a centre of necrosis or cell death. Symptoms can overlap across causal agents, however differing signs and symptoms of certain pathogens can lead to the diagnosis of the type of leaf spot disease. Prolonged wet and humid conditions promote leaf spot disease and most pathogens are spread by wind, splashing rain or irrigation that carry the disease to other leaves.
The Virgin Mountains are a mountain range of the northeastern Mojave Desert, located in Clark County, southeastern Nevada and Mohave County, northwestern Arizona.
Cleome is a genus of flowering plants in the family Cleomaceae, commonly known as spider flowers, spider plants, spider weeds, or bee plants. Previously, it had been placed in the family Capparaceae, until DNA studies found the Cleomaceae genera to be more closely related to the Brassicaceae than the Capparaceae. Cleome and clammyweed, can sometimes be confused. The simplest way to differentiate the two is to compare the seedpods which project out or down on cleome and up on clammyweed.
Cleome hassleriana, commonly known as spider flower, spider plant, pink queen, or grandfather's whiskers, is a species of flowering plant in the genus Cleome of the family Cleomaceae, native to southern South America in Argentina, Paraguay, Uruguay, and southeast Brazil. It has also been introduced to South Asia, including the Haor area of Bangladesh.
Bacterial blight is a disease of barley caused by the bacterial pathogen Xanthomonas campestris pv. translucens. It has been known as a disease since the late 19th century. It has a worldwide distribution.
Pseudomonas cichorii is a Gram-negative soil bacterium that is pathogenic to plants. It has a wide host range, and can have an important economical impact on lettuce, celery and chrysanthemum crops. P. cichorii was first isolated on endives, from which it derives its name. It produces 6-aminopenicillanic acid. Based on 16S rRNA analysis, P. cichorii has been placed in the P. syringae group.
Pseudomonas ficuserectae is a nonfluorescent, Gram-negative, soil bacterium that causes bacterial leaf spot on a Japanese fig, from which it derives its name. Based on 16S rRNA analysis, P. ficuserectae has been placed in the P. syringae group.
Xanthomonas fragariae is a species of proteobacteria. It is a leaf spot disease found in strawberries.
The White Pine Range Wilderness is a 40,013-acre (16,193 ha) wilderness area in southwestern White Pine County, in the U.S. state of Nevada.
Calochortus monophyllus is a North American species of flowering plants in the lily family known by the common name yellow star-tulip.
Cleome gynandra is a species of Cleome that is used as a green vegetable. It is known by many common names including Shona cabbage, African cabbage, spiderwisp, cat's whiskers, chinsaga and stinkweed. It is an annual wildflower native to Africa but has become widespread in many tropical and sub-tropical parts of the world. It is an erect, branching plant generally between 25 cm and 60 cm tall. Its sparse leaves are each made up of 3–5 oval-shaped leaflets. The flowers are white, sometimes changing to rose pink as they age. The seed is a brown 1.5 mm diameter sphere. The leaves and flowers are both edible. The leaves have a strong bitter, sometimes peppery flavor similar to mustard greens.
Cleome platycarpa is a species of flowering plant in the cleome family known by the common names golden bee plant and golden spiderflower. It is native to the western United States from northeastern California to Idaho, including the Modoc Plateau, where it grows on clay and volcanic soils in the sagebrush. It is an annual herb branching at the base into several erect stems up to about 60 centimeters tall. The stems are green tinted with purple, coated densely in glandular hairs, and lined with many leaves. Each leaf is divided into three small leaflets. The top of each stem is occupied by a raceme of many flowers. Each flower has generally four yellow sepals and four yellow petals around a center of many yellow stamens. The fruit is a flat, hairy capsule up to 2.5 centimeters long which hangs on the long, remaining flower receptacle.
Bacterial leaf scorch is a disease state affecting many crops, caused mainly by the xylem-plugging bacterium Xylella fastidiosa. It can be mistaken for ordinary leaf scorch caused by cultural practices such as over-fertilization.
The Waterman Mountains are a low mountainous landform in Pima County, United States. Notable among the tree species is the elephant tree which species exhibits a contorted multi-furcate architecture; most of these froze in the cold winter of 2011. The Waterman Mountain range is in the Ironwood Forest National Monument.
Oxystylis is a monotypic genus of flowering plants currently considered a part of the cleome family containing the single species Oxystylis lutea, which is known by the common name spiny caper. It is native to the Mojave Desert straddling the border between California and Nevada. It grows in rocky and sandy desert habitat, often on alkaline soils. This is an annual herb producing an erect, branching stem which may reach 1.5 meters in height. The leaf is made up of three thick, firm leaflets 2 to 6 centimeters long, borne on a stout, straight petiole. The inflorescence is a dense head of flowers clustered about the stem at the leaf axils, each flower with four small yellow petals. The fruit is a small white or purple nutlet bearing the spine-like remnant of the flower receptacle.
In botany, a fascicle is a bundle of leaves or flowers growing crowded together; alternatively the term might refer to the vascular tissues that supply such an organ with nutrients. However, vascular tissues may occur in fascicles even when the organs they supply are not fascicled.
Xanthomonas campestris pv. vesicatoria is a bacterium that causes bacterial leaf spot (BLS) on peppers and tomatoes. It is a gram-negative and rod-shaped. It causes symptoms throughout the above-ground portion of the plant including leaf spots, fruit spots and stem cankers. Since this bacterium cannot live in soil for more than a few weeks and survives as inoculum on plant debris, removal of dead plant material and chemical applications to living plants are considered effective control mechanisms.
