Priming maritime pine megagametophytes during somatic embryogenesis improved plant adaptation to heat stress

WRKY11 was upregulated in priming-derived embryonal masses, and also derived from primed embryogenic masses, that also showed better osmotic adjustment. These improved plants can be obtained by heat priming

On remarkable properties of primes near factorials and primorials

The distribution of primes is quite irregular. However, it is conjectured that if p is the smallest prime greater than n! + 1, then p – n! is also prime. We give prove that if a prime number p satisfies n! + 1 > p ...

Euclidean Primes Have the Minimum Number of Primitive Roots

Denote by A(p) the number of primitive roots modulo a prime p. We show that for an arbitrary .epsilon. > 0 there exists a prime p such that A(p)/p < .epsilon. . Moreover, for an arbitrary Euclidean prime p we prove that A(q...

On distribution of primes around factorials

The distribution of primes is quite irregular. We prove the following theorem which however allows some relularity: If a prime number p satisfies n!+1prime larger than a given natural numb...

Straddled numbers: numbers equal to the sum of powers of consecutive primes from the least prime factor to the largest prime factor

Positive integers equal to the sum of powers of consecutive primes from the least prime factor to the largest prime factor are studied. They are called the straddled numbers and their properties are derived. There are also ...

Prime filters of hyperlattices

The purpose of this paper is the study of prime ideals and prime filters in hyperlattices. I-filter and the filter generated by a in L are introduced. Moreover, we introduce dual distributive hyperlattices, and I-filter in dual dis...

Primitive root biases for prime pairs I: Existence and non-totality of biases

We study the difference between the number of primitive roots modulo p and modulo p+k for prime pairs p, p+k. Assuming the Bateman Horn conjecture, we prove the existence of strong sign biases for such pairs. More importantly, we prove that ...
