Bacillus subtilis strains lacking penicillin-binding protein 1 (PBP1), encoded by ponA, required greater amounts of Mg2+ or Ca2+ for vegetative growth or spore outgrowth than the wild-type strain and strains lacking other high-molecular-weight (HMW) PBPs. Growth of ponA cells in a medium low in Mg2+ also resulted in greatly increased cell bending compared to wild-type cells or cells lacking oth...

The experiments were conducted a protected environment city Jaguari-RS, two growing seasons years 2019 2020. Italian Gaucho cultivars used, rootstock was chosen f...

BACKGROUND AND AIMS Stinging nettle (Urtica dioica) is a herbaceous, dioecious perennial that is widely distributed around the world, reproduces both sexually and asexually, and is characterized by rapid growth. This work was aimed at evaluating the effects of plant maturity, shoot reproduction and sex on the growth of leaves and shoots. METHODS Growth rates of apical shoots, together with fo...

mungbean (vigna radiata (l.) wilczek) or green gram as a dryland grain legume is exposed to varied timings and severity of drought stress, resulting in variability in photoassimilate production. in order to evaluate some physiological responses in one mungbean cultivar to timing and severity of drought stress, a 3-replicate rcbd (randomized complete block design) field experiment was carried ou...

Persea schiedeana, a close relative of avocado (Persea americana), is an important part of agroforestry systems and diets in parts of Mesoamerica, particularly in the coffee growing areas of southeastern Mexico and Guatemala, where it is known as chinene, coyo, and yas. Little research attention has been given to this species, other than as a rootstock for avocado. Research carried out in six v...

Grafting techniques represent an efficient tool to enhance plant growth and development. The study aims explore the effects of different grafting combinations on eggplants under diverse greenhouse conditions. Eggplant cultivar Black bell (Bb) was employed as scion, while hybrid F1 Beaufort (Be) Solanum torvum (To) were utilized rootstock. hypothesis behind this pertains incompatibility with F1....

The relationshipbetween secondary metabolites content and antioxidant activity was studied in aerial parts of Nasturtium officinale R. Br., at various altitudes and periods of growth in north of Iran. Total phenolics (TP), and total flavonoids (TF) contentsin aerial parts of the plantwere investigated spectrophotometrically and their antioxidant activitieswere obtained byTotal Antioxidant Capac...
